FOREWORD
RF Energy Exposure and Product Safety
Guide for Portable Two-Way Radios
ATTENTION!
Before using this product, read the RF Energy
Exposure and Product Safety Guide that ships with
the radio which contains instructions for safe usage
and RF energy awareness and control for
compliance with applicable standards and
regulation.
ACOUSTIC SAFETY
Exposure to loud noises from any source for
extended periods of time may temporarily or
permanently affect your hearing. The louder the
radio’s volume, the less time is required before your
hearing could be affected. Hearing damage from
loud noise is sometimes undetectable at first and
can have a cumulative effect.
To protect your hearing:
• Use the lowest volume necessary to do your job.
• Turn up the volume only if you are in noisy
surroudings.
• Turn down the volume before connecting
headset or earpiece.
• Limit the amount of time you use headsets or
earpieces at high volume.
• When using the radio without a headset or
earpiece, do not place the radio’s speaker
directly against your ear.

DESCRIPTION
The Tactical PTT/VOX Interface Module with Ear
Microphone consists of two parts, the Push-To-Talk
(PTT) / Voice Operated Transmission (VOX)
Interface Module and the Bone Conduction Ear
Microphone.
The PTT / VOX Interface Module is equipped with
high performance VOX interface and a large PTT
button. The guarded ring around the PTT button
secures the PTT button from any accidental actuate
and can be removed when situations require.
The superior VOX interface is enhanced by high
speed Digital Signal Processor (DSP) and detects
only signal matching to human voices. The VOX
circuit will be set off and recognized steady and
trouble-free VOX transmission even under intense
noise.
The module ensures transmission without clipping
the initial part of the speech by temporarily storing
the voice in memory and release it in tune with the
radio’s ready to transmit state. The built-in digital
audio amplifier helps to increase the radio’s volume
with a lower audio output. The module operates on
electrical power supplied from the radio.
The Bone Conduction Ear Microphone is equipped
with a high performance bone conduction
microphone and receiver built into the ear piece.
Unlike the conventional boom microphone, the bone
conduction microphone picks up your voice directly
from the ear canal, so ambient noise is minimized to
its lowest level.

into the ear canal and place
the cable behind the ear as
shown in the picture. The
Bone Conduction Ear
Microphone can be worn in
the right or left ear.
Note: Once the kit has been installed, the radio
microphone and the radio speaker will be
disabled. The user must use the Bone
Conduction Ear Microphone to transmit and
receive calls.
Performance
To minimize interference and optimize the Bone
Conduction Ear Microphone performance, make
sure the accessory cable does not coil around the
radio antenna during use.
DO NOT set the volume level too loud.
