2-8 Care to be Taken in the Field
1) Check for trouble symptoms.
2) Check for connection to optional devices and other peripheral devices.
3) Record the contents of the battery backup memory.
4) After working, restore the equipment according to the above mentioned contents of memory if
necessary.
5) After completion of work, put back the peripheral devices to the original condition.
2-9 Precaution for Monitor repairing
1) Subjecting the unit to strong shocks may result in damage to the CRT or malfunction, therefore
care must be taken when transporting or installing the unit.
#
DANGER
#
High voltages are present inside the display chassis. Only experienced
technicians should touch internal parts.
#
DANGER
#
The electric charge has remained in CRT after the power switch is turned off.
Because the high voltage is usually used for CRT. So make the electric
charge escape with a grounding stick which is connected to the ground of the
chassis and through the resistance for high voltage (Approx. 1M " ) before
removing the anode cap.
Some electric charge remains in CRT after escaping with a grounding stick.
Do not touch the metallic part of anode cap with bare hands, when detaching
the anode cap directly.
2) CRT with the deflecting yoke is already adjusted to the best condition. Do not touch the
deflecting yoke and the magnet of the neck part.
3) Be sure to detach the metallic goods such as a wrist watch from your body before doing the repair
work.
To prevent the secondary damage and the electrical shock, the matters above should be taken into
careful consideration.
