3. Press H+ to set the hour for the "1 ON" time.
4. Press M+ to set the minute for the "1 ON" time.
5. Press the Timer (P) button again. The display will show "1 OFF" (the first OFF program).
6. Press D+ to select the day(s) for this OFF program (usually matching the ON program).
7. Press H+ to set the hour for the "1 OFF" time.
8. Press M+ to set the minute for the "1 OFF" time.
9. Repeat steps 1-8 for additional ON/OFF programs (up to 28).
10. After setting all desired programs, press the Clock (⏰) button to exit program mode and return to the current time display.

7.2. Manual Override

The Manual button allows you to cycle through different operating modes:

• ON: The output is continuously ON, ignoring all programs.
• AUTO: The timer operates according to the programmed ON/OFF settings.
• OFF: The output is continuously OFF, ignoring all programs.

Press the Manual button repeatedly to switch between these modes. Ensure the timer is in AUTO mode for programmed operation.

8. Maintenance

• Clean the timer switch periodically with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Ensure the terminals are free from dust and debris to maintain good electrical contact.
• The internal battery provides backup for program settings during power outages. If the display remains blank after a power outage, a full reset and reprogramming may be necessary.

9. Troubleshooting

9.1. Timer Not Responding / Blank Display

• Solution: Perform a full reset by pressing the recessed C/R button with a pointed object. This often resolves initial setup issues or unresponsive behavior.
• Check Power: Ensure the timer is receiving power.

9.2. Programs Not Activating

• Check Mode: Ensure the timer is set to AUTO mode using the Manual button.
• Verify Settings: Double-check all programmed ON/OFF times and selected days for accuracy.
• Current Time: Confirm the current day and time are set correctly.

9.3. Incorrect Voltage / Model

• Verify Model: Ensure the specific model you have (e.g., 12V DC, 220V AC) matches your power supply and intended load. Using an incorrect voltage model can lead to malfunction or damage.

10. User Tips

• If the timer appears unresponsive upon first use, a quick reset using the C/R button can often resolve the issue and get it working correctly.
• Always double-check your programmed ON/OFF times and selected days to avoid unexpected operation.
