TMAA10-11 Electret Handset
Installation Instructions
Introduction
The TMAA10-11 handset improves the audio quality in
noisy environments, and provides the user with privacy
(‘private handset mode’ programmed).
When your radio receives a call and the handset is mounted
in its locking cradle, you can hear the call from your radio’s
internal speaker, and also from any connected remote
speaker.
If you remove the handset from its cradle when you receive
a call, you can hear the call from your radio’s internal
speaker, from any connected remote speaker, and from the
handset earpiece.
If private handset mode is programmed, the radio’s internal
and external speakers are muted, and the call can only be
heard from the handset earpiece.
The TMAA10-11 uses an electret microphone, and comes
with the handset to radio cord pre-wired to the handset
mounting plate.
If fitting the TMAA10-11 handset to a TM8200 remote installation that uses components
from kit TMAA03-16, the existing head and body remote interfaces don’t support audio
feed to the microphone socket and therefore can’t be used with the handset. If fitted on
the radio, the TMAA03-16 kit can be identified by radio body interface, which doesn’t
have a connector fitted on the right-hand port. For correct operation, the installation
should be upgraded to one of the enhanced remote kits such as TMAA03-19.
Handset Installation
1 Press the push-button and remove the handset from the locking cradle.
2 Disassemble the locking cradle by removing the four locking cradle screws.
3 Drill a hole for the handset to radio cord in the chosen mounting surface, and pass the
cord through the hole. The hole must be large enough for the grommet to fit through.
If a smaller hole is required, remove the handset to radio cord from the handset PCB
connector, and drill a hole in the mounting surface just large enough to fit the handset to
radio cord.
Pass the cord through the hole, then reconnect the cord to the handset PCB connector
using the wiring instructions in the diagram “Handset PCB connector wiring”, on
page 2.

4 Screw the handset mounting plate to the required mounting surface. Note that mount-
ing screws are not provided in this kit.
5 Clamp the top part of the locking cradle onto the mounting plate, and secure it with the
four locking cradle screws.
Connecting the Handset to the Radio
Notice The microphone-socket grommet must be installed whenever the handset to
radio cord is plugged into the microphone socket. When installed, the grommet has two
functions:
■to prevent damage to the microphone socket when there is movement of the
handset to radio cord, and
■to ensure that the control head is sealed against water, dust and other
environmental hazards.
1 Plug the handset to radio cord into the microphone socket on the radio control head.
2 Slide the grommet along the cord and push two adjacent corners of the grommet into
the microphone socket cavity.
3 Squeeze the grommet and push the remaining corners into position.
4 Check that the grommet is seated correctly in the cavity, as shown in the following dia-
gram.

Radio Programming for Private Handset Mode
If private handset mode is required, the radio needs to be programmed to mute the audio
power amplifier when the handset is out of the cradle. The audio path is then only through
the RX AUDIO line to the handset earpiece.
The following table shows the settings required in the Programmable I/O form of the
radio’s programming application. Refer to the online help of the programming application
for more information.
If private handset mode is programmed, then no audio will be heard from the speakers if
the handset is unplugged.
