SECTION 4

General

It is necessary to perform the maintenance services listed below to keep the
RADAR 1800 in good working conditions.
Proper maintenance of the RADAR 1800 minimizes the possibility of
machine failures.
The maintenance operations that are common to all components of the
RADAR 1800 are listed below.
q Cleaning
Remove dirt, dust, or water-spray from the RADAR 1800 enclosure and
keep it as clean as possible. Use a dry lint-free cloth.
w Screw inspection
Check the screws used to assemble and secure the components of the
RADAR 1800 for loose connection.
e Cabling check
Check the cables connecting between the components (between the scanner
unit and display unit, display unit and power supply, and display unit and
optional devices) for poor connection.
When servicing the RADAR 1800, be sure to turn it
off to prevent electric shock. If a rectifier unit is
used, in particular, turn off power to the display unit.
Note that voltages from the rectifier unit are always
present even if the radar is stopped.

Scanner Unit

When inspecting the scanner unit of the RADAR 1800, be sure to turn off
power to the display unit.
Keep watches or magnetic cards away from the modulator block as it
contains a magnetron having a strong magnetic force.
