INSTALLATION
LOCATION
It is advisable to spend a little time selecting the best location 
for your TX2700. The mounting bracket can be rotated above, 
below or behind the radio enabling the radio to be mounted 
in a wide range of locations. In addition, an optional fl ush 
mounting kit allows the radio to be fl ush mounted in a panel 
or dashboard.
When choosing a location:
• Select a location that won’t expose your radio to
continuous direct sunlight which could cause overheating.
• Ensure the location allows a free fl ow of air around the
heat sink on the back of the radio.
• The microphone and all controls should be readily
accessible and the loud speaker easily heard from the 
normal driving position. An extension speaker can be 
installed if required.
• Electronic interference caused by other electronic devices is
best minimized by mounting your TX2700 at least 300 mm 
from such devices, including all wiring and cables. 
INSTALLING THE UNIT
After choosing a location, hold the unit with the mounting 
bracket attached, to the desired position and mark the 
location with a pencil. Remove the mounting bracket from 
the radio and drill the mounting holes. Bolt or screw the 
bracket in place using hardware suitable for the mounting 
surface. The unit is supplied with steel screws, however, if the 
mounting surface is unsuitable for screws you may need to 
replace these with bolts. Remember the fi xings for overhead 
mounted units may have to withstand being driven on 
unsealed roads.
The TX2700 mounting bracket is designed with a unique dual 
position gimbal mounting slot. This design not only allows 
the TX2700 to be tilted over a much greater range, but also 
provides a slim, low profi le mounting position for installations 
where space is very limited.

DC CONNECTIONS
Connect the RED power lead to the positive (+) side of the 
battery or to an accessory point in the vehicle’s fuse box.
Connect the BLACK power lead to the negative (-) side of the 
battery or to a ground point in your vehicle.
NOTE:
The DC Connector is not waterproof. If installed in
an exposed location, the connector should be protected with 
waterproof tape to prevent water ingress.
IMPORTANT:
The RED power lead is fi tted with a 2 Amp
fuse. If the fuse blows, use only a standard 2 Amp (3AG) fuse 
as a replacement. Use of a higher rated fuse or a slow-blow 
type could result in damage to your radio which would void 
the warranty.
If required, an extension speaker may be installed to improve 
sound levels in noisy environments or in locations further 
away from the driving position. For locations exposed to wa-
ter we recommend the SPK45B which will fi t to the supplied 
adaptor that connects to the extension speaker socket on the 
rear of the radio.

ANTENNA INSTALLATION
It is essential to select a good quality, high effi ciency, 
27 MHz antenna. A poor quality antenna or one not designed 
for the specifi c frequency band you are using 
will give very poor performance.
