Hardware error. The mains
supply line failure signal is
constantly high
Switch off ISM-3, wait for 10 seconds and
switch it on again. If an error is still indicated,
ISM-3 should be returned for repair.
It is possible to continue by pressing .
However, the mains supply unit is defective and
should be replaced / repaired (possibly a bad
wire connection).

Switch off ISM-3, wait for ten seconds and
switch it on again. If an error is still indicated,
ISM-3 should be returned for repair.
