The ATW-CHG3 is a two-bay charging station for use with 3000 Series (fourth generation) handheld (ATW-T3202) and body-pack (ATW-T3201) transmitters. The station charges NiMH batteries (not included) while they are housed within a transmitter. It will automatically shut off if alkaline or damaged batteries are detected. Once fully charged, a maintenance charging function ensures that batteries retain their full power for as long as the transmitter remains in the charging station. 
 
The ATW-CHG3 is equipped with power and charging status indicator LEDs for easy monitoring. 
 
Using the AT8687 link kit and AD-SA1230XA AC adapter, up to five ATW-CHG3 charging stations can be linked and powered by a single power supply. The AT8687 and AD-SA1230XA may be purchased separately or bundled with an ATW-CHG3 charging station: ATW-CHG3EXP (charger and link kit), ATW-CHG3AD (charger and AC adapter).
