5. Setup

5.1 Initial Charging

Before first use, it is recommended to fully charge the radio's internal battery using the USB charging cable.

  1. Connect the micro USB end of the provided cable to the Micro USB Input Port on the radio.
  2. Connect the standard USB end to a USB power adapter (not included) or a computer's USB port.
  3. The battery indicator lights will show charging progress. Once all lights are solid, the radio is fully charged.

6. Operation

6.1 Powering On/Off and Volume Control

Rotate the Volume Control / Power Switch clockwise to turn the radio on and increase the volume. Rotate counter-clockwise to decrease volume and turn the radio off.

6.2 Radio Function (AM/FM/WB)

  1. Extend the Telescopic Antenna fully for optimal reception.
  2. Use the Band Selector to choose between AM, FM, or WB (Weather Band).
  3. Rotate the Tuning Dial to scan for radio stations.
  4. Adjust the Volume Control to your desired listening level.

Note: Weather Band (WB) provides access to NOAA weather alerts and broadcasts in applicable regions.

6.3 Flashlight

Press the dedicated Flashlight Button (usually located on the side or front) to turn the flashlight on. Press again to turn it off.

6.4 SOS Alarm

In an emergency, press and hold the SOS Button (often yellow) to activate a loud siren and a flashing light. Press it again to deactivate the alarm.

6.5 Charging the Radio (Internal Battery)

The radio can be charged using three methods:

  • USB Charging: As described in Section 5.1. This is the fastest and most efficient method.
  • Hand Crank Charging: Unfold the Hand Crank and rotate it clockwise or counter-clockwise at a steady pace (approximately 130-150 RPM). A few minutes of cranking can provide enough power for a short period of radio use or flashlight operation.
  • Solar Charging: Place the radio with the Solar Panel facing direct sunlight. This method is ideal for maintaining charge or slow charging in emergency situations. It is less efficient than USB or hand cranking for rapid charging.

6.6 Charging External Devices (Power Bank Function)

The radio can act as a power bank to charge small electronic devices like smartphones.

  1. Connect your device's charging cable to the USB Output Port on the radio.
  2. The radio's internal battery will begin charging your external device.
  3. Note: This will drain the radio's internal battery. Use this function judiciously, especially in emergency situations.

7. Maintenance

  • Cleaning: Wipe the radio with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
  • Storage: Store the radio in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, it is recommended to fully charge the battery every 3-6 months to maintain battery health.
  • Battery Care: Avoid fully discharging the battery frequently. Recharge it when the battery indicator shows low power.
