LEAKAGE CURRENT CHECK
Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis
resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the
power cord is less than 460 kohms, the unit is defective.

CAUTION IN SERVICING
When you have replaced the 1U-3291 Unit, or changed the CPU, DSP, or their peripheral parts, be sure to perform “RESET”
by pressing S803 on the DSP Unit Ass’y in the state of Standby or Power-on.
Q
WIRE ARRANGEMENT
If wire bundles are untied or moved to perform adjustment or parts replacement etc.,be sure to rearrange them neatly as they
were originally bundled or placed afterward.
Otherwise, incorrect arrangement can be a cause of noise generation.

CAUTION:
Before returning the unit to the customer, make sure you make either (1) a

WARNING:
Parts marked with this symbol have critical characteristics.
Use ONLY replacement parts recommended by the manufacture.
CAUTION:
Before returning the unit to the customer, make sure you make either (1) a
leakage current check or (2) a line to chassis resistance check. If the leakage
current exceeds 0.5 milliamps, or if the resistance from chassis to either side
of the power card is less than 460 kohms, the unit is defective.
WARNING:

CAUTION:
c
Before returning the unit to the customer, make sure you make either (1) a
leakage current check or (2) a line to chassis resistance check. If the leakage
current exceeds 0.5 milliamps, or if the resistance from chassis to either side
of the power card is less than 460 kohms, the unit is defective.
