CHP SERIES

HEAVY DUTY EAR DEFENDER HEADSET

Quick Start User Guide

Version: V1.5

Designed in the United Kingdom

Introduction

Thank you for purchasing the Entel CHP ear defender headset. This user guide will explain the features of your headset, which with care should provide many years of trouble-free operation.

The CHP Series headset provides hands-free communications in high ambient noise environments.

Fitting

Place the ear defenders over your ear with the comfort headband (or hardhat) on top of your head. Position the adjustable boom microphone to sit as close to your mouth as possible. Attach the remote PTT unit to your clothing around the lapel area.

Operating Instructions

Ensure the radio is switched off, remove the rubber dust cover and insert the CHP connector onto the accessory socket. Secure by turning the connector screw clockwise until finger-tight (do not over tighten). You can now turn on your radio.
Press the PTT button to transmit and release to receive.
If you detach the CHP accessory, please always replace the dust cover to protect your radio's accessory connector.

Important

Always switch the radio off before attaching an audio accessory. Models that are certified to ATEX and IECEx have been clearly labelled. Should, in the course of use, any labels be removed or become illegible please return the accessory to Entel for relabelling.
