DESCRIPTION
Many mobile radio users prefer the feel, use, and privacy of
a telephone style handset over that of a standard mobile
microphone. The GMUN1006 Telephone Style Handset Kit
provides a slimline telephone style handset with PTT and
two function buttons as well as a hang-up cup, and
mounting hardware for use with the mobile radio. Table 1
lists the items included in this installation kit.
INSTALLATION
Carefully select the installation location for the GMUN1006
Telephone Style Handset. Plan the installation so that the
handset’s location is within convenient reach of the user,
but will not interfere with the vehicle’s operation. Also,
consider seating, leg space, and the operation of other
vehicle accessories. The location chosen for a handset
should be similar to the location chosen for a standard
mobile microphone and hang-up clip.

and the unit could break free on collision.
Mount the bracket only in a location which
allows the self tapping screws to solidly
anchor into a metal surface.

The mounting screws can damage cables
and wires that run under some mounting
surfaces in the vehicle. Be careful to avoid
mounting the bracket above those
locations.

Mounting the Adjustable Angle Bracket
Once an installation location has been decided, refer to
Figure 1 and perform the following steps:
1. Verify that the selected mounting surface is strong
enough to support the mounting hardware and handset.
2. Use the base of the adjustable angle bracket as a
template to center punch and drill four 3.2 mm (0.136”)
diameter holes. Be careful not to damage any wires or
any other vehicle components when drilling the holes.
3. Use the four 8-18 x 3/4” tapping screws and the internal
lockwashers provided to mount and secure the bracket.
4. Place the hang-up cup on top of the bracket mounting
surface and secure it using the four M4 x 6 mm
machine screws and lockwashers provided.
5. Select the angle between the two bases of the
adjustable angle bracket (from 0° to 110°) and tighten
the two adjusting screws.

the handset from the hang up cup will disconnect the radio
speakers and the receive audio will only be heard in the
earpiece of the handset. With the functional button (F1 or
F2) the external speaker may additonally be switched ON/
OFF. Adjust the handset’s speaker volume using the
radio’s volume control. Press and hold the handset’s PTT
to transmit, and release it to receive.
