Radio Installation Considerations
All Uniden radios and associated accessories are tested before
shipment to ensure operational status. However, since vehicle
configuration in which Uniden radios and accessories are installed are
non-standard, Uniden recommends the following installations
considerations.
Power Requirements
The SMH250D and SMU250K require a 13.6V DC, 10 ampere power
source with a negative ground. Install a fuse in the power leads
near the power source to protect the power source compartment
and passenger compartment from fire and electrical hazards. (The
AMX 120A Power Cable is equipped with an in-line 15 ampere fuse.)
If the radio is connected directly to the vehicle battery, a fuse must be
installed as close to the battery terminal as possible.
Route power leads to minimize proximity to other electrical systems
such as instruments, engine electrical components, braking systems,
entertainment systems, etc.
Secure power leads to supporting structures or components with
insulated clamps that completely isolate the power leads from the
supporting structures or components. When power leads are routed
through a firewall, bulkhead, or similar structure, use a rubber
grommet to protect power leads from chafing.
Antenna
Follow antenna manufacturer’s mounting instructions. Mount antenna
in a location which gives the highest unrestricted radiation pattern. Use
low loss, 95% shielded, Teflon coaxial cable between antenna and
radio antenna jack. Keep antenna cable length short to insure
maximum power output.
Mounting
Mount the equipment with your safety and the safety of others in
mind. Do not obstruct the operator's physical or visual access to the
controls. Ensure easy access to the microphone and radio
