   • Note: The USB port supports charging only and does not support programming.
2. Base Charging:
   • Connect the US plug adapter to the charging base.
   • Place the radio into the charging base, ensuring proper contact with the charging terminals.
   • The indicator light on the base will typically turn red during charging and green when fully charged.

4. Operating Instructions

4.1. Power On/Off and Volume Control

• To power on the radio, rotate the Power/Volume knob clockwise until you hear a click.
• To power off, rotate the knob counter-clockwise until it clicks.
• Adjust the volume by rotating the same knob clockwise to increase and counter-clockwise to decrease.

4.2. Channel Selection and Frequency Input

• The UV-21R supports 999 channels. Use the Up/Down navigation keys to scroll through programmed channels.
