CAUTION

Danger of short circuit!

Technical defects can cause a short circuit.

￿Before putting the headset into operation, ensure that the socket of the on- board DC power supply system is protected by a 1 A fuse.

There are different options for powering the headset:

• Connection to the on-board DC power supply system (12 – 35 VDC) via a mounted 3-pole XLR socket or the cigarette lighter socket

• Power supply via two batteries/rechargeable batteries inserted in the control unit (to be ordered separately)

Connection via a 3-pole XLR socket

The Adapter-P-XLR-3adapter cable (optional accessory available from your Sennheiser partner) allows you to connect the headset to the on-board DC power supply system (12 – 35 VDC) via a mounted 3-pole XLR socket.

￿Have a 3-pole XLR socket (optional accessory) mounted by a technician qualified to perform this

type of installation.

￿ Connect the Adapter-P-XLR-3adapter cable to the mounted 3-pole XLR socket.

￿Connect the hollow jack plug of the adapter cable to the hollow jack socket on the control unit.
