From a device that has never been flashed to pressing one button to change the page: every step, with a photograph of what you should be looking at. The written versions live on the flash page and the setup page.
相片陸續加緊 · Photographs are still being taken
未影到嘅位會出一個虛線框，寫住嗰張相要影乜。框係暫時嘅，相片放上去就會自動變返張相。
Where a photograph is still missing you will see a dashed box describing the shot. The box is temporary: as soon as the picture is added it takes its place automatically.

用電腦燒一次Flash it once, from a computer
電腦 Computer
一世人做一次。用電腦開 Chrome 或者 Edge，去燒錄頁，揀型號，撳「安裝」。條線暫時唔好插住。Once in the device's life. On a computer running Chrome or Edge, open the flash page, pick the model, press Install — with the cable still unplugged.
相片準備中 Photo coming soon要影：電腦全螢幕影燒錄頁，睇到型號揀咗 reTerminal E1002、紅色「安裝 Install」掣，同埋枱面上仲未插嘅 USB-C 線。
To photograph: the flash page on a laptop screen, model set to reTerminal E1002, the red Install button clearly visible, and the USB-C cable lying unplugged on the desk beside it.assets/guide/flash.jpg
撳「安裝」之前，線係唔使插嘅。Before you press Install, nothing is plugged in.
要留意 · Worth knowing
燒錄一定要用電腦 —— iPhone、iPad、Android 同 Safari 都做唔到，唔係你做錯嘢。燒完之後部電腦就冇嘢做，之後全部用電話。
Flashing needs a desktop browser; phones, tablets and Safari cannot do it at all. After this one step the computer is finished — everything else happens on a phone.

個窗開咗，先插線Plug in only after the picker opens
電腦 Computer
撳完「安裝」，瀏覽器頂會彈一個叫你揀 port 嘅細窗。就係嗰陣先插 USB-C 線落部機 —— 個窗會即時多咗一個新項目，嗰個新出現嘅就係你部機。揀佢，撳「連接 Connect」。Pressing Install opens a small port-picker window at the top of the browser. That is the moment to plug the USB-C cable into the device: a new entry appears in the list the instant you do, and the one that just appeared is yours. Pick it and press Connect.
相片準備中 Photo coming soon要影：瀏覽器頂嗰個揀 port 嘅細窗開住，同一格相入面見到一隻手正在將 USB-C 線插落部機。窗入面應該見到一項 wchusbserial 或者 CH340。
To photograph: the browser's port-picker window open at the top of the screen, with a hand in the same frame in the act of plugging the USB-C cable into the device. The list should show one entry named wchusbserial… or CH340.assets/guide/plug-in.jpg
個窗開住嗰陣插線，個新項目即刻彈出嚟。Plug in while the window is open and the new entry appears at once.
相片準備中 Photo coming soon要影：撳咗「連接」之後嘅燒錄畫面 —— 進度條跑到大約一半，下面嘅記錄框見到 Writing… 之類嘅字。
To photograph: the flashing screen after Connect — progress bar around halfway, with the log box below showing lines like Writing….assets/guide/flashing.jpg
大約一分鐘。行到 100% 就自己重新開機，條線唔好住住拔。About a minute. At 100% it reboots by itself — leave the cable in.
插咗都冇新項目？ · Nothing appeared when you plugged in?
多數係條 USB-C 線淨係叉到電、傳唔到資料（好多平價線都係咁）。換一條確定傳到資料嘅線，或者換個 USB 插口再試。
Almost always a charge-only cable — plenty of cheap USB-C leads carry power and no data. Swap in a known data cable, or try another USB port.

撳住綠色掣，掃 QR 入 WiFiHold the green button, scan the QR, join Wi-Fi
部機 + 電話 Device + phone
撳住個綠色掣，直到聽到「嘀」一聲先放手（通常 5–10 秒）。唔好數秒數 —— 聽到聲先算。放手之後畀成一分鐘佢：先靜一靜，再響三聲，跟住慢慢畫個新畫面出嚟。Hold the green button until you hear the beep — usually 5 to 10 seconds. Don't count; wait for the sound. After you let go, give it a full minute: a silent pause, then three rising tones, then a slow redraw.
相片準備中 Photo coming soon要影：影實部機側邊個綠色掣，一隻手指撳住佢，近鏡到睇得出係邊個掣（唔好影到成部機縮到好細）。最好見到部機其餘兩個掣，令人知綠色嗰個係邊個。
To photograph: a close shot of the green button on the side of the device with a finger holding it down — close enough that there is no doubt which button it is, and ideally with the other two buttons in frame for comparison.assets/guide/hold-button.jpg
撳到聽見「嘀」一聲先放手。Let go on the beep, not on a count.
相片準備中 Photo coming soon要影：部機個芒出咗「設定 WiFi Set up WiFi」嗰版（兩個 QR），一部電話攞住喺前面掃緊左邊嗰個 QR，電話芒見到相機同個掃描框。個芒上面啲字要睇得清楚。
To photograph: the device showing the “設定 WiFi / Set up WiFi” screen with its two QR codes, and a phone held in front of it scanning the left-hand one — the phone's camera view visible, and the words on the panel legible.assets/guide/wifi-qr.jpg
掃左邊嗰個 QR，加入部機自己嘅 WiFi「YAT-xxxx」。The left QR joins the device's own network, “YAT-xxxx”.
加入咗之後，設定頁通常會自己彈出嚟。等一等，唔使即刻去揸網址。Once you join, the page usually pops up on its own — give it a moment.
揀你屋企個 WiFi，入密碼，撳儲存。要揀 2.4 GHz 嗰個 —— 部機連唔到淨係得 5 GHz 嘅網絡。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.
撳咗儲存之後個芒會停住大半分鐘先變 —— 正常嚟嘅，等佢。The screen sits unchanged for about half a minute after you save. That is normal; wait it out.
呢一步嘅逐句解釋喺設定頁。The line-by-line version of this step is on the setup page.
04
喺電話揀你想睇嘅嘢Choose what it shows, on your phone
電話 Phone
WiFi 入好之後，個芒會出「揀內容」嗰版同一個大 QR。掃佢，部機自己嘅設定頁就開喺你電話度。撳「加版」揀你想睇嘅，填好設定，最後撳「儲存落部機」。With Wi-Fi saved, the panel shows the “揀內容 / Choose what it shows” screen and a large QR. Scan it and the device's own settings page opens on your phone. Add a page, fill in its settings, then press Save.
相片準備中 Photo coming soon要影：一部手機直度攞住，芒上面係部機嘅設定頁打開咗頁面庫（一格格預覽圖），最好連部機喺後面做背景。要見到底部「儲存落部機」條橫額。
To photograph: a phone held upright showing the device's settings page with the pack library open (the grid of page previews), ideally with the device itself out of focus behind it. The “儲存落部機 / Save” bar at the bottom should be visible.assets/guide/library.jpg
同一版可以加多過一次 —— 想睇兩區天氣，就加兩版，每版各揀各嘅地區。The same page can be added more than once: two districts' weather means two copies, each with its own district.
撳咗「儲存落部機」之後，個芒要成 30 秒先畫完。呢段時間部機唔會覆你部電話 —— 正常嚟嘅，唔好熄個頁。After you save, the panel takes about 30 seconds to redraw and stops answering your phone while it does. That is expected — keep the page open.
05
平時點用：三個掣Day to day: the three buttons
部機 Device
設定好咗之後，平時唔使再開電話。Once it is set up, the everyday moves are all on the device itself.
相片準備中 Photo coming soon要影：部機側邊三個掣嘅近照，睇得清楚邊個係綠色嗰個、邊個喺上、邊個喺下。（標註可以事後加，張相本身只需要影清楚三個掣同佢哋嘅相對位置。）
To photograph: a close shot of all three buttons on the side of the device, clear enough to tell which is the green one and how they are arranged. Labels can be added afterwards; the photograph only needs the buttons and their positions.assets/guide/buttons.jpg
三個掣，三件事。Three buttons, three jobs.
撳一下綠色掣就放手 —— 同佢講你想睇邊版（「天氣」、「巴士」…）。A short tap on the green button: say which page you want.
上下兩個掣 —— 上一版 / 下一版。The other two step to the previous and next page.
撳住綠色掣，直到「嘀」一聲 —— 入設定，改版或者改 WiFi。Hold the green button until it beeps to get back into setup and change things.
撳一下之後淨係「嘀嘀」兩聲、之後乜都冇？即係「收到，但做唔到」 —— 通常係仲未入語音 key，或者部機得一版嘢。Two soft chirps and nothing else means “heard you, can't act” — usually no voice key yet, or only one page installed.
06
部機嘅設定The device's own settings
電話 Phone
同一個設定頁落面，仲有成部機嘅設定：自動輪播、唔更新嘅時間（夜晚唔好嘈）、嘀嘀聲，同埋語音 key。改完一樣要撳「儲存落部機」。Below the page list on the same settings page: auto-rotate, quiet hours, the beeps, and the voice key. These are device-wide rather than per page, and they ride the same Save.
相片準備中 Photo coming soon要影：手機芒轆到「部機嘅設定」嗰段：自動輪播、唔更新嘅時間、嘀嘀聲、語音 key 幾格一齊入鏡。語音 key 嗰格唔好影到真 key（留空，或者用假字）。
To photograph: the phone scrolled to the “部機嘅設定 / Device settings” section, with auto-rotate, quiet hours, beeps and the voice key all in frame. The key field must be empty or hold obvious dummy text — never a real key.assets/guide/settings.jpg
設定頁十分鐘冇人撳就會自己收工。想再入返去，同一個動作：撳住綠色掣直到「嘀」一聲。Setup closes itself after ten idle minutes. To get back in, the same gesture as always.
之後想改 · Changing it later
加版、改設定、換次序，做法一模一樣：撳住綠色掣直到「嘀」一聲，掃個 QR。唔使插線，唔使開電腦，唔使開帳戶。
Adding a page, changing a setting or reordering later is the same gesture every time: hold the green button until it beeps and scan the QR. No cable, no computer, no account.
※
出問題嘅時候When something goes wrong
兩頁都有一張「徵狀 → 通常係乜事」嘅表：燒錄相關嘅喺燒錄頁，設定同日常使用嘅喺設定頁。
Both pages carry a symptom-and-cause table: flashing problems on the flash page, setup and everyday problems on the setup page.
