8.9  OPTIONAL MMB-84 FLUSH MOUNT INSTALLATION
1. To assist in flush mounting, a template has been included. Use this tem-
plate to find the mounting location.
2. Use the template to mark the location where the rectangular hole is to be
cut. Confirm the space behind the dash or panel is deep enough to accom-
modate the transceiver (at least 6 inches or 15 cm deep).
There should be at least 1/2 inch (1.3 cm) between the transceiver’s heatsink
and any wiring, cables or structures.
3. Cut out the rectangular hole and insert the transceiver.
4. Fasten the brackets to the sides of the transceiver with the lock washer nut
combination; so that the mounting screw base faces the mounting surface
(see Figure 2).
5. Turn the adjusting screw to adjust the tension so that the transceiver is tight
against the mounting surface.

8.10  OPTIONAL ENHANCED RAM+ SECOND STATION MIC INSTALLATION
The GX3500S is capable of using up to 2 Enhanced RAM+ mics to remotely
control the Radio, DSC and PA/Fog functions. In addition the GX3500S can
operate as a full function intercom system. With 2 RAM+ mics connected the
GX3500S or RAM+ mics can selective call each station individually or all at one
time.
1. Connect the RAM+ MIC Cable to the RAM MIC CONNECTOR on the rear
panel, then tighten the Cable Nut (See Figure 3).
2. Referring to Figure 3, make a 1.2” (30 mm) hole in the wall, then insert  the
RAM+ MIC Cable into this hole. Connect the Gasket and Mount Base to the
RAM+ MIC Cable Connector using the Nut.
3. Drill the four Screw holes (approx. 2 mm) on the wall, then install the Mounting
Base to the wall using four screws.
4. Put the Rubber Cap on to the Nut. The installation is now complete.
5. Wires for a external speaker are provided on the RAM+ mic cable. Connect
any 8 Ohm external speaker. When connected the RAM+ controls the vol-
ume level of this speaker.
RAM+ or External Speaker Selection
By default the RAM+ internal speaker is turned on, however using the RAM+
mic this speaker can be turned off so the external speaker can be used.
1. Press and hold the [
CALL/SET]
 key on the RAM+ Mic.

9  CONTROLS AND INDICATORS
NOTE
This section defines each control of the transceiver. See Figure 4 for
location of controls. For detailed operating instructions refer to section
“10 BASIC OPERATION.”
VOLUME CONTROL (
VOL)
Adjusting this control clockwise, increases the audio volume level.
SQUELCH CONTROL (
SQL)
Adjusting this control clockwise, sets the point at which random noise on
the channel does not activate the audio circuits but a received signal does.
This point is called the squelch threshold. Further adjustment of the squelch
control will degrade reception of wanted transmissions.
MICROPHONE CONNECTOR
Connect the supplied MH-63
A6 Hand Microphone to this jack.
KEY BUTTON
[
16/9]
