FM53/FM54 VOICE PROJECTION UNIT
The VPU is designed for the Avon FM53/FM54 APR to allow non-obstructed weapon sighting and easier operation. The VPU is attached to the front of the VREU (Variable Resistance Exhalation Unit), and can be removed to allow for APR exhalation resistance changes. The pass-through lead provides an interface to the APR connector, and houses a second connector to attach additional communication equipment while the VPU is being worn. The VPU must be used with the Voice Projection Unit Microphone or Microphone Assembly. Additional communication kits are available on request. The unit requires a single Lithium Ion battery (123A not supplied), and the microphone is powered by the VPU.
