4.1 Initial Charging

Before first use, it is recommended to fully charge the radio's internal battery. You have several charging options:

USB Charging: Connect the provided USB cable to the DC IN port on the radio and to a standard USB power adapter (not included) or a computer USB port. The charging indicator will illuminate.
Hand Crank Dynamo: Fold out the hand crank from the back of the radio (Figure 3.4). Rotate the crank clockwise or counter-clockwise at a steady pace for 3-5 minutes to provide initial power or emergency charge.
Solar Charging: Place the radio with the solar panel (on top) facing direct sunlight. This method is ideal for maintaining charge or slow charging over longer periods.

4.2 Antenna Extension

For optimal radio reception, extend the telescopic antenna fully when listening to FM or Shortwave bands. For AM reception, the internal antenna is generally sufficient, but adjusting the radio's orientation may improve signal.
