Sennheiser SH350 manual Inserting / replacing the the batteries

2.Connecting the headset to the battery pack (except HMEC 352, HMEC 355 and HMEC 356)

The NoiseGard™ electronics of the HMEC 350, HMEC 355-C, HMEC 372, HMEC 450 and HMDC 372 headsets can also be powered via the BP-04 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.

￿Insert four AA size alkaline-manganese batteries (IEC LR 6). Observe correct polarity when inserting the batteries.
