5. Setup and Installation
- Unpack: Carefully remove the timer from its packaging.
- Initial Charge: Plug the timer into a standard 120V AC grounded wall outlet for at least 30 minutes to charge the internal battery backup. The display should illuminate.
- Set Current Time: Before programming, set the current time and day. Refer to the "Operating Instructions" section for details on using the SET and +/- buttons.
- Connect Devices: Plug the appliances you wish to control into the two grounded outlets on the timer. Ensure the appliances' power switches are in the "ON" position if you want the timer to control their power.
6. Operating Instructions
The timer features a digital display and four control buttons:
- ON/OFF: Manually turns the connected devices on or off, overriding current program settings temporarily.
- SET: Used to enter programming mode for setting time, day, and on/off schedules.
- -/RDM: Decreases values during setting. Also activates/deactivates Random mode (RDM) for security lighting.
- +/AUTO: Increases values during setting. Also switches between Manual ON, Manual OFF, and AUTO modes.
6.1. Setting Current Time and Day
- Press and hold the SET button until the display flashes.
- Use the +/AUTO or -/RDM buttons to adjust the current hour. Press SET to confirm.
- Repeat for minutes and then for the current day of the week.
- Press SET again to exit time setting mode.
6.2. Manual Override
Press the ON/OFF button to cycle through ON, OFF, and AUTO modes. In AUTO mode, the timer follows its programmed schedule. In ON or OFF mode, the timer will remain in that state until manually changed or the next programmed event occurs (depending on model specifics).
7. Programming the Timer
The CJ Tech 605 allows for multiple ON/OFF programs over a 7-day cycle. The exact number of programs may vary. Follow these general steps:
- Press the SET button repeatedly until "PROG" or "PROGRAM" appears on the display, along with a program number (e.g., "1 ON").
- Use the +/AUTO or -/RDM buttons to select the desired day(s) for this program (e.g., MON-FRI, SAT-SUN, or individual days). Press SET to confirm.
- Set the desired ON time using the +/AUTO or -/RDM buttons for hours and minutes. Press SET to confirm.
- The display will then show "1 OFF". Set the desired OFF time for the same program using the +/AUTO or -/RDM buttons. Press SET to confirm.
- Repeat steps 2-4 for additional programs (e.g., "2 ON", "2 OFF", etc.).
- Once all programs are set, press the ON/OFF button to return to normal operating mode. Ensure the timer is in "AUTO" mode for programs to execute.
7.1. Astronomical Feature (Dusk/Dawn)
If your model supports astronomical features, it will automatically adjust ON/OFF times based on local sunrise and sunset. This feature is typically enabled or configured within the programming mode. Consult the display for specific indicators (e.g., "DUSK", "DAWN") when setting programs. You may need to set your geographical region or zip code for accurate operation, though this model's interface suggests a simpler implementation.
8. Maintenance
- Cleaning: Disconnect the timer from the wall outlet before cleaning. Wipe the exterior with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
- Storage: If storing the timer for an extended period, ensure the internal battery is charged periodically to maintain its life. Store in a cool, dry place.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Timer display is blank. | No power to the outlet or internal battery is depleted. | Check the wall outlet with another device. Plug the timer in for at least 30 minutes to charge the battery. |
| Connected device does not turn on/off as programmed. | Timer is not in AUTO mode. Device's power switch is off. Incorrect program settings. | Press +/AUTO until "AUTO" is displayed. Ensure the connected device's power switch is ON. Review and correct program settings. |
