4. Consumption current measu r ement
o Supply voltage: 5.8 V
o Consumption current :
400 µA max . when ON (after pushing of the
ON key).
45 µA max . when OFF ( a fte r pushing of the
OFF key).
Be sure to press the ALL RESET sw i tch
before the measurement .
3. If the lithum battery is not installed properly and
with good electrical contact problems such as
flickering display o r damage to other parts could
result. Be sure the battery is properly installed.
2. When the memory module PWB is replaced it
could be installed slightly out of alignment due
to the play in the screw holes . Since this could
l ead to improper operation , replace the PWB
again and press the ALL RESET switch befor
resuming operation.
1. Since it is difficult to troubleshoot the main PWB because of chassis mounted on top of it, it is suggested that
you use the service tool chassi s (LCHSS1134CCZZ) which is smaller in size. Install this chassis for trouble-
sho o ting purposes only . When unit is repaired, replace with original chassis.
