2. To initialize the unit
This device employs a microprocessor to perform various
functions and operations. If interference generated by an external
power supply, radio wave, or other electrical source results in
accident which causes the specified operations and functions to
operate abnormally.
To perform a result, please follow the procedure below.
1.Set the unit to the standby mode
2.Press and hold down the MEMORY button, then press the
DISPLAY button.
3.The segments of the F.L.tube light on and the unit is set to the
test mode.
4.'Clear' is displayed when the power switch is pressed in the
state of the test mode and the memory is cleared.
1. Replacing the fuse
This symbol located near the fuses indicates that the
fuse used is fast operating type. For continued protection against
fire hazard, replace with same type fuse. For fuse rating refer to
the marking adjacent to the symbol.
Ce symbole indique que le fusible utlise est a rapide.
Pour une protection permanente, n'untiliser que fusibles de
meme type. Ce darnier est la qu le present symbol est
appse.
