Operating Instructions

The iH402B features two independent alarms. Follow these steps for each alarm:

1. Press and hold the Alarm 1 or Alarm 2 button until the alarm time flashes on the display.
2. Use the + or - buttons to adjust the desired alarm hour. Ensure the AM/PM indicator is correct.
3. Press the respective Alarm button again to confirm the hour and proceed to minute adjustment.

5. Press the Alarm button one last time to save the alarm time. The alarm indicator will light up, confirming the alarm is active.
6. To turn off an active alarm, press the corresponding Alarm button once. The alarm indicator will turn off.

An alarm volume switch (High/Low) is located on the back of the unit to adjust the buzzer volume.

2. Snooze Function

When an alarm sounds, press the Snooze button (typically a large button on top of the unit) to temporarily silence the alarm. The alarm will sound again after a preset interval (usually 9 minutes).

3. Display Brightness

The display brightness can be adjusted. Locate the Dimmer or Brightness button (refer to unit for exact location). Press it repeatedly to cycle through various brightness levels, including an option to turn the display off entirely.

4. USB Charging

The iH402B offers two ways to charge your mobile devices:

• Built-in USB Port: Connect your device's USB charging cable to the USB port located on the side or back of the main unit.
• Removable USB Battery Pack: The unit includes a pop-out lithium-ion battery pack with its own USB port. To use it, press the release button (typically on the back) to eject the pack. Connect your device's USB charging cable to the port on the battery pack. To recharge the battery pack, reinsert it into the main unit.

Maintenance

1. Cleaning

Wipe the unit with a soft, dry cloth. Do not use liquid cleaners or abrasive materials, as they may damage the finish.

2. Battery Replacement (Backup)

If the display flickers or settings are lost during a power interruption, the AA backup batteries may need replacement. Open the battery compartment on the bottom of the unit, remove the old batteries, and insert two new AA batteries, observing correct polarity.

Troubleshooting

• Unit does not power on: Ensure the power adapter is securely plugged into both the unit and a working wall outlet. Check the power source.
• Alarm does not sound: Verify that the alarm is set and activated (alarm indicator lit). Check the alarm volume switch on the back of the unit.
• USB charging not working: Ensure the unit is powered on. Check the USB cable connection to both the alarm clock/battery pack and your device. Some devices may require more power than the removable pack can provide for a full charge.
• Time/settings lost during power outage: Replace the AA backup batteries.
• Display is too dim or off: Adjust the display brightness using the dedicated button.
