This unit charges ATW-T220a handheld transmitters and/or ATW-T210a UniPak transmitters (in any combination). Batteries are charged within the transmitters, and the ATW-CHG2 has protective features to preserve the integrity of the transmitters. A built-in safety feature monitors cell voltage and automatically turns off the unit if problems are detected. The unit will also automatically shut off if damaged or alkaline (non-rechargeable) batteries are installed. Maintenance charging prevents battery self-discharge until the transmitter is removed from the charger. Two AA 2000mAh Ni-MH rechargeable batteries are included.

Other recent enhancements to the 2000 Series include the addition of a second operating frequency band for greater flexibility and increased number of simultaneous usages (Band I: 487.125MHz to 506.600MHz). The transmitters’ designs have also been updated with charging contacts. Additionally, a two-position switch on the receiver turns on/off the 12V AC antenna power for use with powered antennas or other in-line RF devices and accessories.
