The ATW-CHG3EXP bundles the ATW-CHG3 two-bay charging station with an AT8687 link kit.<BR><BR>The charging station works with 3000 Series (fourth generation) handheld (ATW-T3202) and body-pack (ATW-T3201) transmitters, charging NiMH batteries (not included) while they are housed within the transmitters. The station will automatically shut off if alkaline or damaged batteries are detected.

The ATW-CHG3 is equipped with power and charging status indicator LEDs for easy monitoring.<BR><BR>The AT8687 kit includes a link cable, link plate, and four plate screws that link the ATW-CHG3 charging station to another ATW-CHG3 or ATW-CHG3N charging station. Additional AT8687 kits can be purchased to link up to five charging stations, all of which can be powered by a single AD-SA1230XA AC adapter (sold separately).
