第二步 · 設定內容 Step two — set up what it shows 用手機就可以 · Works on your phone

按住綠色掣，直到「嘀」一聲。 Hold the green button until it beeps.

不用數秒：聽到「嘀」一聲才放手（通常 5–10 秒）。然後給它一分鐘 —— 靜一靜、響三聲、慢慢畫出一個新畫面，接著螢幕會告訴你下一步。設定頁是裝置自己開的，不用插線，用手機就可以。以後想改，按同一個掣。

Don't count seconds — hold the green button until you hear the beep, usually 5 to 10 seconds. Then give it a full minute: it goes quiet, plays three rising tones, redraws slowly, and tells you what to do next on its own screen. That settings page is served by the device itself — no cable, works from a phone. Same button any time you want to change something.

這一頁只是說明 · This page is only the instructions 這一頁連不到你的裝置，也沒有儲存任何東西 —— 真正的設定頁在裝置自己上面運行，你的手機要和它在同一個 WiFi（或者連上它自己的熱點）才開得到。 This page never talks to your device and stores nothing. The real settings page runs on the device itself; your phone reaches it over your home Wi-Fi, or the device's own hotspot.
01

怎樣進入設定Getting in

  1. 按住綠色掣，直到聽到「嘀」一聲才放手。通常 5–10 秒，不要數秒，聽到聲音才算。（按一下不同 —— 那個是聲控。）Press and hold the green button until you hear the beep. Usually 5 to 10 seconds — wait for the sound, don't let go on a count. A short tap does something else — that's the voice button.
  2. 「嘀」聲響起時你的手還按住 —— 意思是「夠時間了，可以放手」。That tone sounds while the button is still down. It means “long enough — you can let go now”.
  3. 放手之後會靜一靜（幾秒，慢的話二十秒）—— 它正在連 WiFi 和對時。沒有聲音、螢幕又不動，都是正常的。After you release there's a silent pause — a few seconds, up to twenty on a slow network — while it joins Wi-Fi and syncs the clock. No sound, no movement: still fine.
  4. 接著會響三聲，一聲高過一聲 —— 那就是真的進入了設定模式，開始畫新畫面。Then three rising tones: it's in setup mode and has started drawing.
  5. 畫螢幕還要大約 30 秒，期間停在舊畫面。由放手到見到 QR，一分鐘都正常。Drawing takes about another 30 seconds, with the panel still holding the old image. A full minute from letting go to seeing the QR is normal.
  6. 新畫面出現之後，看看是下面哪一個。When it appears, check which of the two below it is.
電量不足的時候 · When the battery is low 電量低過 3.50 V 就不會進入設定，改為顯示一個紅色的「叉住電先設定　Plug in to set up」畫面，上面寫著實際電壓。插上 USB-C 電源，再按住綠色掣直到「嘀」一聲就可以。那個畫面大約五分鐘就會自動變回平時的內容 —— 不是壞了。 Below 3.50 V the device refuses to open setup mode and draws a red “plug in to set up” screen with its actual voltage. Connect USB-C power, then hold the green button until it beeps again. That screen clears itself after about five minutes and normal content returns — nothing is broken.
02

裝置會出其中一個畫面One of two screens

第一次用，裝置還不認得你家中的 WiFi，會出畫面 A 叫你設定。設定好之後，每次進入設定都是畫面 B。

下面兩幅是示意圖，QR 都是畫出來的 —— 真的在你裝置的螢幕上。Both panels below are drawings, not screenshots, and the QR blocks are decorative — the real ones are on your device.

A螢幕上寫著「設定 WiFi」 · The screen says “設定 WiFi / Set up WiFi”

那就去設定 WiFiThen: set up Wi-Fi

  1. 用手機相機掃左邊那個 QR，加入裝置自己的 WiFi「YAT-xxxx」。掃不到就去手機的 WiFi 設定手動揀 —— 密碼印在螢幕上。Scan the left QR with your phone's camera to join the device's own network, “YAT-xxxx”. Can't scan? Pick it by hand in your Wi-Fi settings — the password is on the screen.
  2. 加入之後，設定頁通常會自己彈出。等一等，不用即刻自己輸入網址；等了大半分鐘都未見，才掃右邊那個 QR。Once you join, the page usually pops up by itself. Give it a moment. Only if nothing appears after ~30 seconds, scan the right-hand QR.
  3. 揀你家中的 WiFi，輸入密碼，按儲存。要揀 2.4 GHz 那個 —— 裝置連不到只有 5 GHz 的網絡，這是最常見的失敗原因。Pick your home Wi-Fi, type the password, save. It must be the 2.4 GHz network — the chip cannot join 5 GHz-only networks, by far the most common failure.
  4. 按了儲存之後，螢幕還會停在這個 WiFi 畫面大約半分鐘，沒有「儲存中…」之類的提示。它正在關掉設定網絡、對時、畫下一個畫面。不要按任何東西，等它。After you tap Save, this same Wi-Fi screen stays up for about half a minute, with no “saving…” message. It is closing the setup network, syncing the clock, and drawing the next screen. Don't tap anything, just wait.
  5. 螢幕自己變成畫面 B，就代表 WiFi 設定好了，不用再按掣。When the screen changes to screen B on its own, the Wi-Fi is saved — no second button press needed.
B螢幕上寫著「揀內容」 · The screen says “揀內容 / Choose what it shows”

那就開設定頁Then: open the settings page

  1. 用手機：相機掃那個大 QR，設定頁就會在瀏覽器打開 —— 手機要連著同一個家中 WiFi。On a phone: point the camera at the big QR and the page opens in your browser. Your phone needs to be on the same home Wi-Fi as the device.
  2. 用電腦：照螢幕印著那個名字輸入瀏覽器，例如 http://yat-a13c.local。下面那格幫你少打幾個字。On a computer: type the name printed on the screen, like http://yat-a13c.local. The box below saves you the typing.
  3. 這個 .local 名字每次都一樣，可以收藏做書籤。開不到（有些網絡不支援 .local）就照抄螢幕上那串數字網址。The .local name never changes, so it's safe to bookmark. If it won't open (some networks don't support .local), type the numeric address the screen also prints.
  4. 家中的路由器不讓兩部裝置互相看到（有些會這樣）？就照螢幕的藍色後備區做：手動連 WiFi「YAT-xxxx」輸入密碼，再開 http://192.168.4.1，一樣進到同一個設定頁。If your router isolates devices from each other (some do), follow the blue fallback block on the screen: join the device's own Wi-Fi「YAT-xxxx」by hand with the password shown, then open http://192.168.4.1 — same page, other route.
螢幕紅字寫著「屋企 WiFi 連唔上」 · If the screen says it can't reach your Wi-Fi 意思是記住了的那個 WiFi 今次連不上（改了密碼、換了路由器，或者一時收不到）。大 QR 會變成連去裝置自己的 WiFi，掃完在瀏覽器輸入 http://192.168.4.1 就進到設定。想改 WiFi 就按住綠色掣直到「嘀」一聲，再做一次 —— 螢幕上也是這樣寫。 The saved network didn't come up this time — a changed password, a new router, or just a bad moment. The big QR becomes the device's own Wi-Fi instead; join it and open http://192.168.4.1. To change the saved network, hold the green button until it beeps again, as the screen says.

瀏覽器說「不安全 Not Secure」 · Your browser will say “Not Secure” 這是正常的，不用擔心。網址是 http:// 開頭，沒有加密證書 —— 因為它根本沒有離開過你家中的網絡，只是你的手機和裝置之間對話，不經任何公司的伺服器。 Expected, and safe here. The address is plain http:// because a device on your own network cannot hold a certificate for a name only your house knows. Nothing you type leaves your home network — no server in the middle.
03

進入設定頁之後Once you're in

揀你想看的內容Pick your pages

整個頁面庫就在設定頁裡面 —— 天氣、警告、巴士和港鐵、潮汐、新聞、家庭告示板。一部裝置最多放 16 版，按掣就轉到。

The whole pack library is in there — weather, warnings, bus and MTR, tides, news, a family noticeboard. Up to 16 pages per device; the buttons flip between them.

按儲存，等它畫Save, then let it draw

按儲存之後，裝置要大約 30 秒重畫螢幕。這 30 秒它不會回應你，連自己的熱點都會斷一斷 —— 設定頁會自己等，完成會告訴你。不要重複刷新，不要關掉頁面。

Saving triggers a ~30 second redraw during which the device answers nothing and its own hotspot briefly drops. The page waits it out and tells you when it's done. Don't refresh, don't close the tab.

按「完成」就結束Press “done” when you're finished

畫完，你揀的版就會回來，底下有一條藍色帶寫著「設定緊 · 喺手機撳「完成」收工」。按「完成」，那條帶就會消失，裝置照舊去睡。忘記按也不要緊 —— 十分鐘沒有動作它會自己結束，一樣畫回正常畫面。

Your page comes back with a blue band across the bottom reading “Setup mode — tap Done on your phone”. Pressing Done clears the band and returns the device to its normal cycle. Forgot to press it? After ten idle minutes it does the same thing by itself.

它會自動結束 · Both screens close themselves 設定不會一直開著，開著就等於一直亮著 WiFi 電台耗電。十分鐘沒有人碰過，兩個畫面都會自動結束：
  • 畫面 B（揀內容）—— 螢幕畫回你揀的版，藍色帶消失，裝置照舊去睡。
  • 畫面 A（設定 WiFi）—— 裝置去睡，半小時後自己再試連舊網絡（不會抹走記住了的 WiFi）。
自動結束不是壞了，也不會有東西不見。想再進去，同一個動作：按住綠色掣直到「嘀」一聲。（在設定頁上每按一下都會重新計十分鐘，不會做到一半關掉。） Setup doesn't stay open — that would keep the Wi-Fi radio lit. After ten minutes with nobody touching it, both screens close by themselves: screen B goes back to drawing your pages and drops the blue band; screen A sleeps and quietly retries the saved network half an hour later, without forgetting it. Nothing is lost. To get back in, the same gesture as always: hold the green button until it beeps. Using the settings page keeps resetting the ten minutes, so it won't close under you mid-job.
之後想改 · Changing it later 以後想加版、改設定、調次序，都是同一招：按住綠色掣直到「嘀」一聲，掃那個 QR。不用插線、不用開電腦、不用開帳戶。 Adding a page, changing settings or reordering later is the same gesture: hold the green button until it beeps and scan the QR. No cable, no computer, no account.
04

按一下，跟它說話Tap it and talk

同一個綠色掣：按住到「嘀」一聲是進入設定，按一下就放手是告訴它你想看哪一版。

忘記可以說什麼？· Forgot what you can say? 同時按兩個箭嘴掣（← ＋ →）會出一頁幫助，列出你的版和可以說的話。按任何一個掣就回去。 Press both arrow buttons together for a help page listing your pages and what you can say. Any button takes you back. Day to day, each page also prints its own words along the bottom edge.

怎樣用How

按一下綠色掣，等它「嘀」一聲高音才開口 —— 那一聲就是「可以說了」。說出你想看那一版的名字，例如「天氣」、「新聞」、「小巴」、「潮汐」、「恒指」。它錄大約四秒，然後低一度「嘀」一聲，就轉版，再用大約 30 秒重畫。

Tap the green button and wait for the high beep before speaking — that beep means “go”. Say the name of a page: “天氣”, “news”, “minibus”, “tides”. It records about four seconds, chirps lower to say it has you, then switches page and takes ~30 seconds to redraw.

要先輸入一條語音 keyIt needs a voice key first

聲音要交給聽寫服務轉成文字，所以要一條你自己的 key。在設定頁捲到「部機嘅設定」→「語音 key」，貼上去按「存落部機」（不用按大的那個「儲存」）。沒有 key 一樣看得到所有版，只是不能用聲音轉版。

Speech is turned into words by a transcription service, so it needs a key of your own. In the settings page, scroll to Device settings → Voice key, paste it, and press Save key. Everything else works without one.

聽聲音就知道The sounds tell you

輕輕「嘀嘀」兩下 —— 收到你按，但做不到：未輸入 key，或者未設定 WiFi，麥克風根本沒有開過。
高音一聲 —— 可以說了。接著低一度那一聲 —— 錄完，正在處理。
兩聲由低升高 —— 認到了，正在轉版，然後重畫。
一下低沉長「嘟」 —— 認不出，或者一時上不到網，版面不會變。可以試頁面庫裡面那個名字。

Two soft chirps on the same note: heard the press, can't act — no key yet, or no Wi-Fi; the microphone never powered. One high beep: speak. A lower one: recording done. A rising pair: recognised, switching. One long low buzz: not recognised, or it couldn't reach the network — the page is left alone.

這一步會離開你家 · This is the one part that leaves your home YAT 其他功能都不經中介，聲控不同：你說的那四秒會上傳到你自己揀的聽寫服務。不想就不要輸入 key —— 沒有 key，麥克風永遠不會開，按多少次都只是那兩聲。 Everything else YAT does goes straight to public APIs with nothing in between. Voice is the exception: those four seconds are uploaded to the transcription service whose key you supplied. Don't want that? Don't add a key — the microphone is then never powered at all, and the button just chirps.

出問題的時候When something goes wrong

徵狀 Symptom通常是什麼事 What it usually is
按了一段時間，還未有「嘀」聲Held it a while — still no beep不要放手，繼續按住。裝置要先醒過來才開始計時，所以由你按下去那一刻計，隨時七、八秒才響（十秒都試過）。聽到聲音才放手 —— 數著秒數就放手，是最常見的失手。再不是就是按錯了掣，或者電量不足（插上 USB-C 電源再試）。Keep holding. The device needs a moment to wake before it starts counting, so from your finger's side it can take seven or eight seconds, sometimes ten. Release only on the sound — letting go on a count is the single most common miss. Otherwise it's the wrong button, or the battery: plug in USB-C power and retry.
放了手，一分鐘都靜悄悄、螢幕又不動Silence and a still screen for a minute after letting go正常。放手之後它靜靜地連 WiFi 和對時（幾秒到二十秒），再響三聲，然後畫大約 30 秒。由放手計一分鐘都還正常，過了一分半鐘都沒有變，才當它沒有進入設定。Expected. After you let go it silently joins Wi-Fi and syncs the clock (a few seconds, up to ~20), then plays three tones, then spends ~30 seconds drawing. A full minute from release is still normal. Only treat it as failed after about 90 seconds.
掃了 QR，頁面開不到Scanned the QR, the page won't open手機要連著同一個 WiFi。還是不行就照螢幕的藍色後備區做：手動連裝置自己的熱點，再開 http://192.168.4.1。Your phone must be on the same Wi-Fi. If it still fails, follow the screen's blue fallback block: join the device's own hotspot by hand and open http://192.168.4.1.
掃到 QR，但頁面只有白底黑字，寫著「介面載入唔到 — 檢查手機有冇上網」The QR works, but the page is a plain page reading “介面載入唔到 / Couldn't load the interface — check your phone has internet”裝置沒有壞，它正在好好回應你 —— 這一版就是它自己的後備版。完整的介面要即場由這個網站取回來，所以問題是你的手機上不到網（或者一時連不到這個網站）。裝置的狀態和版清單照樣看得到，只是暫時揀不到新版。讓手機重新上網，再開同一條網址就可以。The device is fine — it is answering you, and this plain page is its own built-in fallback. The richer interface is fetched live from this website, so what failed is your phone's internet (or its route to this site). Status and page list still work; only browsing the library is unavailable. Get the phone back online and open the same address again.
設定頁做到一半沒有反應The settings page stops responding halfway多數是裝置正在畫螢幕（30 秒）。等它。真的沒有反應，就再按一次綠色掣、聽到「嘀」一聲才放手，重新進入設定 —— 已經儲存的東西不會不見。Almost always the ~30 second redraw. Wait it out. If it really is gone, hold the green button until it beeps again — anything already saved is still saved.
按一下綠色掣，只有輕輕「嘀嘀」兩聲，之後什麼都沒有A tap on the green button gives two soft chirps and nothing else這兩聲的意思是「收到，但做不到」。多數是還未輸入語音 key（設定頁 →「部機嘅設定」→「語音 key」，看第 04 節），再不是就是未設定過 WiFi。同樣兩聲也代表「只有一版，沒有別的可以轉」—— 先加多一版再用左右掣。Those two chirps mean “heard you, can't act”. Usually there is no voice key yet — settings page → Device settings → Voice key, see section 04 — or the device has no Wi-Fi saved. The same pair also means “only one page is installed, nowhere to step”; add a second page first.
裡面完全沒有版There are no pages at all新機就是這樣 —— 它會出一版歡迎頁，等你揀第一版內容。That's a brand-new device. It shows a welcome page until you choose your first one.
裝置根本未燒錄過The device has no firmware yet要先用電腦（Chrome / Edge）燒一次韌體：燒錄頁。Flash it once from a computer running Chrome or Edge — see the flash page.
