5.2 INSPECTION AND MAINTENANCE/TROUBLE SHOOTING
5.2.1 GENERAL
To maintain the originally designed functions and the life cycle, regular check and
maintenance are required. As inappropriate inspection and maintenance rather deteriorate
the equipment and shorten the life cycle, the following instructions should be kept in
user's mind.
5.2.2 TOOLS & TEST APPARATUS
For the purpose of the correct inspection, the below measuring tools should be prepared
and used.
(1) Necessary measuring tools for each test item
Test item Measuring tools Others
General voltage, currency, resistance for which do
not require any precision such as for power feature.
Multi-Tester
5.2.3 DAILY CHECK AND MAINTENANCE
■
Inspection of input power voltage(12V - 35V): 24V recommendable.
In order for the voltage to be available, work on maintaining the batter of the power supply.
In case of 12V, there are possibilities of the power failure and malfunction occurrence when in operation
and in case of 35V, there are possibilities of fuse brokage and circuit damage.
■
Tightened status of back connectors
In case of poorly tightened power connector, there are possibilities of power down and
malfuction occurrence and in case of poorly tightened antenna, it is impossible to receive the
satellite signal.
■
Get rid of LCD dust
5.2.4 6 months check up(Adjusting period by position)
* When checking the inside of the equipment, separate the power input connector (SCN-16-2P) and check.
■
Get rid of dust inside the equipment
Brush off dust with compressed air - Wet dust may be the cause of circuit damage or malfunction.
5.2.5 2 years check up(Adjusting period by position)
■
Wash circuit board and contact points of connectors.
Wash the surroundings of contact point wiring with activators (LPS cleaner).
* Only skilled personnel are allowed to do the work.
