Installation - Uniden SMH 4000 Service Manual

Planning the Installation
The SMH 4000 radio can perform reliably
if you install all the parts properly. A bad in-
stallation may result in adverse vehicle
operation. Before you start installation
make sure that you have all of the parts,
tools, and test equipment used in the instal- ly. All Uniden transceivers are factory
lation. Also make sure that all the parts
operate properly and that you have
thoroughly planned the mounting loca-
tions. If you do this, you can avoid
problems and save time. Remember that
planning is the key to a good installation.

tain vehicles may adversely affect vehicle
operations, such as:

Uniden America Corporation is not respon­

Operational Tests
Before you install the transceiver in a
vehicle, make sure that it operates proper-
tested and are in working order when
shipped; however, shipping may affect the
unit's alignment. Perform an operating test
with all parts connected that are used in
the final installation. Check the
transmitter's output power, frequency, and
deviation; the receiver's sensitivity,
squelch operation, audio power, and distor­
tion; and CTCSS. Do not install any part
that has a problem. Correct any problems
before installing the transceiver.
