Rechargeable lithium-ion batteries provide up to 20 hours of beltpack or all-in-one wireless headset operation with each charge. Voice prompts inform users of status changes through the headset, such as "change battery" or "out of range." Electronic mic gain and sidetone adjustments allow for easy, tool-free settings.Sidetone adjustment is not required on the WH200. Selectable momentary or latching button mode allows better management of system resources.

The Beltpack Pouch with internal clip is constructed with santoprene rubber to provide maximum protection on HME DX Series beltpacks. The beltpack is securely locked into the pouch and worn at the user's hip position. All buttons on the beltpack are bump-proofed by the pouch and yet still easily accessible.

The BAT41 is a Li-ion rechargeable battery, used to operate the HME BP200 beltpacks and the WH200 COMMUNICATOR.
