4. While holding the CLOCK button, press UP repeatedly to set the current minute.
5. Release the CLOCK button. The time is now set.

4. Press UP to set the minute for "1 ON".
5. Press PROG again. The display will show "1 OFF" and the time will flash.

7. Press PROG to move to the next program ("2 ON") or to exit programming mode if you have finished.
8. To clear a specific program, navigate to that program (e.g., "3 ON") and press the CLEAR button.

2. Manual Override Function

You can manually switch the timer's output ON or OFF, overriding the current program without deleting it.

• Press the SET button (when not in programming mode) to cycle through the modes: AUTO ON, ON, AUTO OFF, OFF.
• Select ON to keep the connected device continuously on.
• Select OFF to keep the connected device continuously off.
• Select AUTO ON or AUTO OFF to resume programmed operation. The timer will follow the next scheduled ON or OFF event.

3. Random Function

The random function can be used to deter intruders by switching connected lights or other devices on and off at irregular intervals.

• Press the PROG button (when not in programming mode) to activate or deactivate the random function. The "RANDOM" indicator will appear on the display.
• When active, the timer will randomly switch the output ON and OFF within a set period (typically between 6 PM and 6 AM, but refer to specific model details if available).

4. Countdown Function

The countdown function allows you to set a specific duration after which the connected device will switch ON or OFF.

• Press the UP button (when not in programming mode) to enter countdown mode. The "COUNTDOWN" indicator will appear.
• Use the PROG and UP buttons to set the desired countdown duration (hours and minutes).
• Press SET to start the countdown. The display will show the remaining time.
• Once the countdown finishes, the device will switch its state (e.g., if it was OFF, it will turn ON; if it was ON, it will turn OFF).
• To cancel the countdown, press the UP button again.

5. Summer/Winter Time Function

This function allows for quick adjustment for daylight saving time.

• Press and hold the CLOCK button, then press the SET button to toggle between standard time and summer time. The "SUMMER" indicator will appear when summer time is active, and the clock will adjust by one hour.

Maintenance

• Cleaning: Disconnect the timer from the power outlet before cleaning. Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Battery: The built-in rechargeable battery is designed to maintain settings during power outages. If the display becomes dim or settings are frequently lost, ensure the timer is plugged in for several hours to allow the battery to fully charge. The battery is not user-replaceable.
• Storage: Store the timer in a cool, dry place when not in use.

Troubleshooting

• Display is blank or dim: The internal battery may be depleted. Plug the timer into a live socket for at least 30 minutes to charge it. If the issue persists, perform a full reset.
• Timer does not switch ON/OFF as programmed:
  • Ensure the current time and day are set correctly.
  • Verify that the programs are correctly entered (ON and OFF times for each program).
  • Check if the timer is in AUTO ON or AUTO OFF mode (not manual ON/OFF or RANDOM).
  • Confirm that the connected appliance is working and properly plugged into the timer.
• Buttons are unresponsive: Perform a full reset by pressing the RESET button with a pointed object.
• Settings are lost after unplugging: The internal rechargeable battery may not be holding a charge. Ensure the timer is plugged in for an extended period (e.g., 24 hours) to fully charge the battery. If settings are still lost, the battery may need replacement (service required).
