4. Setup Instructions

Figure 3: Visual guide for setting up the timer.

1. Set Programmed Times: The timer dial has segments around its edge. Each segment represents 30 minutes. To set a period when the connected device should be ON, push the corresponding segments down towards the center of the dial. For periods when the device should be OFF, leave the segments in the up position.
2. Set Current Time: Rotate the entire dial clockwise until the 'TIME NOW' arrow on the timer's face points to the current time of day. The dial is marked with hours (1-12) and AM/PM indicators (sun for AM, moon for PM).
3. Set Master Switch: Locate the ON/TIMER switch on the top of the unit. Slide this switch to the 'TIMER' position for automatic operation based on your programmed settings. Slide to 'ON' for continuous power, or 'OFF' to cut power.
4. Plug In: Plug the timer into a standard indoor polarized wall outlet. Then, plug your device into the polarized outlet on the side of the timer.

5. Operating Instructions

Once set up, the timer will automatically turn your connected device on and off according to your programmed schedule. The dial will continuously rotate, indicating the current time.

• Manual Override: To temporarily bypass the timer's schedule, slide the ON/TIMER switch to the 'ON' position for continuous power, or 'OFF' to cut power to the device. Remember to slide it back to 'TIMER' for automatic operation.
• Power Outage: In the event of a power outage, the timer will stop. Once power is restored, you will need to reset the current time on the dial to ensure accurate scheduling.

6. Maintenance

• Cleaning: Disconnect the timer from the wall outlet before cleaning. Wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners or immerse in water.
• Storage: Store the timer in a cool, dry place when not in use.

7. Troubleshooting

• Device does not turn ON/OFF at programmed times:
  • Ensure the ON/TIMER switch is in the 'TIMER' position.
  • Verify that the 'TIME NOW' arrow is correctly aligned with the current time of day.
  • Check that the segments corresponding to the desired ON times are pushed down.
  • Confirm the device plugged into the timer is functioning correctly when directly plugged into a wall outlet.
• Timer is not running:
  • Ensure the timer is securely plugged into a live wall outlet.
  • Check the wall outlet with another device to confirm it has power.
• Timer makes a clicking sound: A faint clicking sound is normal for mechanical timers as the internal mechanism operates. If the sound is excessively loud or unusual, discontinue use and contact support.
