Introduction The UHW/ FHW series offers highly reliable wireless communication headsets for fire and emergency truck operator applications. The UHW/ FHW series provides secured, digitally encoded interference free communications. When operated as part of a wireless system, up to 40 headsets can operate interference free in close proximity to each other1. 1- Although not recommended, under certain circumstances, it may be possible to operate up to 50 head sets in close proximity.
Proper Fit When worn properly, this headset will provide significant hearing protection. If it is not worn properly, the headset’s effectiveness in reducing harmful noise is severely compromised. • The length or vertical fit of the headset ear dome is adjusted by the headband or head strap. Adjust as necessary to achieve a fit that ensures the headset ear dome completely covers the ear. • This headset is intended to be a left dress headset.
Headset Power Switch and Volume Control A power switch with non detented volume control is provided. This control is located on the bottom side of the right ear dome on the UHW-10/ 20 headsets, and on the top side of the left ear dome on the FHW-10 headset. Volume should be set at a comfortably high audio level to optimize performance but not so high as to cause audio distortion and hearing discomfort.
Mic Muffs The headset microphone is covered with a washable, replaceable foam mic muff. This mic muff helps prevent the “pops” and “hisses” that can occur from speaking into a microphone that is close to the mouth. Mic muff To clean or replace the mic muff: O-ring 1. Remove the o-ring. 2. Slip the mic muff off the microphone. 3. At this time, you can decide whether to clean or replace the mic muff.
