Solar power charging
The radio can also be charged with solar power.

1. Expose the solar panel on the top in direct sunlight.
2. The solar power will charge the internal battery when the receiving light intensity reaches its starting point. The CHARGE indicator will turn red when charging.

Note:

• The solar power charging is for maintaining or extending the internal battery life only.
• Do not use solar power for regular charging.

Installing 3 x “AAA” batteries
You can install 3 x “AAA” batteries for emergency power backup.

1. Press on the battery compartment cover and slide it in the direction of the marked arrow.
2. Insert three “AAA” batteries into the battery compartment. Make sure that you match the+ and – symbols on the batteries with the+ and – symbols in the battery compartment.

Note:

• Between the inserted “AAA” batteries and the internal battery, the radio will automatically detect and use either one having the higher power supply voltage.
• If your radio is not to be used for a long period of time, remove the “AAA” batteries to prevent damage or injury from possible battery leakage.
• The radio does not support charging “AAA” batteries.

Tips:

• The unit of frequency of tuned stations is MHz for the FM/WB band and kHz for the AM band.
• Location, conditions of weather, and terrain affect the reception. To improve radio reception, use the radio in a place where radio signals can be easily received such as near a window. Also, adjust the antenna (FM/WB) or reorient the unit itself (AM) for good reception. If the reception problem persists, try changing the installation location.
• Typical broadcasts are within reception distance of 25-40 miles of the weather broadcast station.

• VOLUME dial clockwise to increase the volume.
• Unplug the headphones when listening through speakers. Make sure the appropriate radio band is selected.

The sound is weak, or the reception is poor

• Fully charge the internal battery.
• Replace all the AAA batteries with new ones.
• For FM/WB reception, extend the antenna to its full length, and reorient it for best reception. For AM reception, reorient the unit itself to find the best reception.
• If you are in a building, listen near a window.
• If a mobile phone is placed close to the radio, a loud noise may be heard from the unit. Keep the phone away from the radio.

A small humming noise is heard from the radio
This is not a malfunction. You may hear a small humming noise from the radio depending on the status of the power supply.

the indicator flashes when charging external device
Stop charging external devices, and fully charge the internal battery or insert new AAA batteries before charging out again. This indicates that the battery power drops to a certain level when charging an external device.

Charging out does not work

• Make sure the connector of the charging cable is inserted into the USB OUT SV port securely.
• Check if the Civil indicator is off. In case the internal battery power is too low, the radio won’t start charging out and the indicator won’t light up. Fully charge the internal battery or insert new AAA batteries before charging out.
