The units in this man ual contain a self-diagnostic function.
If an error occurs , the STANDBY/TIMER indicator will auto-
matically begin to flash.
The n umber of times the indicator flashes tr
The n umber of times the indicator flashes tr
anslates to a probab
le source of the prob
lem. A definition of the
STANDBY/
TIMER flash indicators is listed in the instr
uction man ual f or the user’ s kno wledge and ref erence . If an error symptom
cannot be reproduced, the remote commander can be used to re
view the f ailure occurrence data stored in memor
y to
reveal past prob lems and ho w often these prob
lems occur .
1. DIAGNOSTIC TEST INDICATORS
When an errors occurs
, the STANDBY/TIMER indicator will flash a set n
umber of times to indicate the possib
le cause of
the prob lem. If there is more than one error
, the indicator will identify the first of the prob
lem areas .
Result f or all of the f ollo wing diagnostic items are displa
yed on screen. No error has occured if the screen displa
ys a “0”.
