The NoiseGard™ electronics of the HMEC 300, HMEC 305-C, HMEC 322, HMEC 400 and
HMDC 322 headsets can also be powered via the BP-03 battery pack (see
"Recommended accessories" on page 9). The battery pack can be operated either on
standard or rechargeable batteries (not included in the delivery). However, to ensure a
longer operating time, we would recommend using standard AA size alkaline
manganese batteries (IEC LR 6) or NiMH rechargeable batteries.
