Should your Canon CR-1 MKII fail to illuminate the power lamp when the power is turned to the ‘on’ position, the following may have occurred:
a). The power cable is disconnected.
b). An indoor circuit breaker has been tripped.
c). The Instrument has suffered a catastrophic failure.
Ensure that the power cord is properly connected, and that all indoor circuit breakers are currently feeding power. If these remedies fail to power the instrument, your Canon CR-1 has most likely suffered a catastrophic failure to its internal power supply. A repair will be necessary.
