Installation Verification
After completing the installation of the vehicular adapter, check all electrical
wiring for tight connections. Also, check all mechanical parts and wiring for tight
and secure mounting. Check for proper operation of the console, microphone,
speaker, and radio as described in the User Guide, Motorola Solutions
publication MN000350A01-AA. Before placing the radio in the APX VA, check
to see that the universal connector cover has been removed from the radio’s
universal connector. Check existing equipment (sirens, lights, and other radio
equipment) for proper operation.
Note: If alternator or other vehicular noise is present in the received signal or
in the transmission, refer to “Reducing Noise Interference in Mobile
Two-Way Radios,” Motorola Solutions publication 68P81109E33. This
publication may be ordered separately from Motorola Solutions
