4.2 User Routine Maintenance
4.2.1 Quarterly
y
Dust should be removed from the air filters. This may be performed by
removing the two left hand front panel fans, and the power supply mounting
bracket, in order to remove and clean or replacing the fan filters. Alternatively,
the air filters may be cleaned with a strong vacuum cleaner, by applying the
vacuum cleaner’s hose over the air intakes and removing built up dust and
residue.
y
The station should be “keyed” (placed into transmit mode) and all fans
observed for normal operation. Replace any fans that may have failed.
y
Using a DV/IP compatible mobile or portable radio (“the test radio”), place the
test radio into “ECHO” mode and “TECHNICIAN” display mode, and make
several ten second voice transmissions through the station from a location
where normal or better coverage is routinely experienced. The test may be
performed at the station’s installation (tower) location. Observe the two frame
error readings on the front panel of the test radio. Typically 1 or less frame
errors should be observed. If an unusually high number of errors are
observed, contact your factory authorized service person or the factory.
4.2.2 Annually
y
The transmitter frequency and power output should be checked by a factory
trained service technician using service procedures recommended by the
factory.
y
The receiver temperature controlled crystal oscillator should be checked by a
factory trained service technician using service procedures recommended by
the factory.
