9.9.6 Adjustment
When you have finished installing the scanner and display units and connecting
cables, turn on the power to the display and scanner units and check to see if they
operate normally without problem. Then make adjustments according to details
in section 7.2.2 Initial radar display setup in the user manual. Be sure to follow
these adjustments or the radar picture will not display a true image.
9.10 Preventive maintenance
Surface cleaning
– to keep the CRXX cabinet and display screen clean, wipe the
surfaces with a clean damp cloth. For heavier cleaning, use a clean, damp cloth
which has been dipped in a solution of a mild dish detergent and water. Wring
out firmly before wiping the unit.
)
Never use cleaning solutions containing spirit or alcohol.
Electrical connections
– periodically check the electrical connections. Make
sure that connections are tight and that no cables are frayed or worn.
Radar antenna
– periodically check that the scanner’s fitting bolts are tight and
not corroded. Every 6 to 12 months an even coating of grease should be applied
to the entire surface of the antenna drive gear with a spatula or brush.
Most of the maintenance of the radar antenna should be left to qualified person-
nel. If there are problems with the performance, please contact your authorized
dealer.
)
Warning! Do not open the radome before the cable between the radar antenna
and CRXX has been disconnected. It is
not
sufficient just to turn off the power
by the switch, as the radar antenna is still supplied power inside.
