4.3 Manual ON/OFF Control

The "ON/OFF" button allows you to manually change the current output state of the timer jack without affecting the programmed schedule.

1. If the timer jack is currently ON and you wish to turn it OFF manually, press the "ON/OFF" button. The display will change to "OFF".
2. If the timer jack is currently OFF and you wish to turn it ON manually, press the "ON/OFF" button. The display will change to "ON".
3. After changing the state, press the "OK" button to confirm the manual override. The timer's programmed functions will continue to execute as planned, and the manual override will be temporary until the next programmed event.

5. Maintenance

• Battery: The timer features an internal rechargeable battery that does not require replacement.
• Cleaning: Wipe the device with a dry, soft cloth. Do not use liquid cleaners or immerse the device in water.
• Storage: Store the timer in a cool, dry place away from direct sunlight and extreme temperatures.

6. Troubleshooting

• Screen is blank/Timer not responding:

  This may occur after long periods of non-use due to the internal battery discharging. Plug the timer into a power supply for at least 30 minutes to charge. Then, press the "RES" button to restore the display and functionality.

• Timer not executing programs:

  Ensure that all timing settings were confirmed by pressing the "OK" button after programming. Also, check the current time setting to ensure it is accurate.

• Difficulty in programming:

  The timer uses a cursor operating system. Ensure you are using the "L/R" buttons to move the cursor and the "+/-" buttons to change values. Always press "OK" to confirm each step or group.
• Indicator light is off but device is ON (or vice versa):

  The indicator light corresponds to the electrical output of the jack. If the screen displays "ON" and the light is off, or "OFF" and the light is on, there might be an internal issue. Ensure the device is properly plugged in and the appliance is functional. If the issue persists, contact support.
