5. Setup
5.1 Initial Reset
Upon first use or after a prolonged period without power, the timer may need to be reset. Use a pointed object (like a toothpick) to press the 'C' (Reset) button located on the front panel. This will clear all previous settings and restore the timer to its factory default state.
Video 1: Demonstrates how to reset the timer switch using the 'C' button. This video features a similar model (CN101A) but the reset procedure is identical.
5.2 Setting Current Time
To set the current day and time:
- Press and hold the Clock button (usually labeled with a clock icon).
- While holding the Clock button, press the D+ button to adjust the current day (MO, TU, WE, TH, FR, SA, SU).
- While holding the Clock button, press the H+ button to adjust the current hour (0-23 for 24-hour format).
- While holding the Clock button, press the M+ button to adjust the current minute (0-59).
- Release the Clock button to save the current time.

6. Operating Instructions
6.1 Programming ON/OFF Times
The timer switch supports up to 16 ON/OFF programs. To set a program:
- Press the P button to enter programming mode. The display will show '1 ON'.
- Use the D+, H+, and M+ buttons to set the desired ON time for the first program. You can select specific days or a block of days using D+.
- Press the P button again. The display will show '1 OFF'.
- Use the D+, H+, and M+ buttons to set the desired OFF time for the first program.
- Repeat steps 1-4 for additional programs (up to 16 ON/OFF pairs).
- After setting all desired programs, press the Clock button to exit programming mode and save the settings. The timer will return to normal operation.

6.2 Manual Mode
The MANUAL button allows you to override programmed settings temporarily. Pressing it cycles through different modes:
- ON: Keeps the output permanently ON.
- OFF: Keeps the output permanently OFF.
- AUTO: Follows the programmed ON/OFF schedules.
To temporarily turn off the display and save battery, press and hold the MANUAL button for 5 seconds. To turn it back on, press and hold for another 5 seconds. Settings are retained.
7. Maintenance
7.1 Battery Backup
The timer switch includes a built-in rechargeable NiMH lithium battery. This battery maintains the time, display, and programmed data for up to 180 days in the event of a power loss. No user maintenance is typically required for this internal battery.
7.2 Cleaning
Clean the exterior of the timer switch with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these may damage the casing or display.
8. Troubleshooting
8.1 Common Issues and Solutions
- Display is blank: Check the power supply connections. If power is present, the internal battery might be fully discharged. Allow time for it to recharge when connected to power.
- Timer not switching: Verify that the timer is in AUTO mode. Check your programmed ON/OFF times for accuracy. Ensure the load is within the specified capacity.
- Incorrect time: Reset the current time as described in Section 5.2.
8.2 Error Codes
If there are setting errors, the LCD may display the following codes:
- E1: Indicates that the START time has not been set for a program.
- E2: Indicates that the END time has not been set for a program.
To cancel or reset programs if settings are incorrect, press the C/R button. If all buttons are locked (no response), press and hold C/R for 8 seconds to unlock.
