Buttons Overview
The X-JSQ016 features a left button (multi-function) and an upper right rotation button (primary control for timing).
| Button | Functions |
|---|---|
| Left Button | – Power: Turn the device on/off. – ECO: Adjust backlight brightness (bright ↔ dark). – Volume: Adjust sound (max → min → mute). |
| Upper Right Rotation Button | Controls timing (start/pause/reset for forward/countdown timers). |
1. Power Button (Left Button)
- Turn On: Press the left button to power up the device.
- Turn Off: Press the left button again to power down.
2. Forward Timing (Count-Up Timer)
Use this mode to track elapsed time (e.g., 1s, 2s, 3s, 5s, 10s, 20s, 30s, minutes, hours).
- Start:
- Power on the device.
- Briefly press the upper right rotation button to begin counting up from “00:00:00” (hours:minutes:seconds).
- Pause: Press the upper right rotation button again to stop counting.
- Reset:
- With the timer paused, hold down the upper right rotation button.
- Release to reset the timer back to “00:00:00”.
3. Countdown Timer
Set a specific time to count down (e.g., 30s, 1min, 5min, 10min, 30min, 1h, etc.).
- Set Time:
- 5-Second Increments: Slowly rotate the upper right rotation button clockwise (→) to add 5 seconds at a time (e.g., 5s → 10s → 15s…).
- Minutes/Hours: Rotate the button quickly clockwise to skip to larger increments (e.g., 1min, 5min, 10min, 1h, etc.).
- Initial State Limit: If starting from the initial (unadjusted) state, rotate the button slowly counterclockwise (←) to set a maximum of 11 hours and 59 minutes (11:59:00 max).
- Start: After setting the desired countdown time, press the upper right rotation button to begin the countdown.
- Pause: Press the upper right rotation button again to pause the countdown.
- Reset:
- With the countdown paused, hold down the upper right rotation button.
- Release to reset to the previously set countdown time (or return to the initial state if no prior setting).
4. ECO Button (Left Button – Backlight Control)
- Press the left button to toggle the backlight between bright (full illumination) and dark (dimmed) modes. Useful for low-light environments.
5. Volume Button (Left Button – Sound Control)
Adjust the device’s sound (e.g., alarm/beep volume):
- First Press: Increase volume to maximum.
- Second Press: Decrease volume to minimum.
- Third Press: Mute the sound (press again to unmute).
Key Notes:
- The upper right rotation button is the primary control for all timing functions (start/pause/reset). Use slow/counterclockwise rotation for precise adjustments (5s increments or max 11:59:00 in initial state).
- The left button cycles through power, ECO, and volume functions—press it to switch between these modes.
- Forward timing always starts from “00:00:00” and counts upward until paused or powered off.
