How to Disable Panel Operations (Key Lock Function)
Operation
It is possible to disable the front panel keys by
pressing the FAST/LOCK(3s)/LOCAL key on the
left of the encoder. Hold this key for three or more
seconds to lock the panel keys. The keys are locked
when the LED beside the key turns red. To cancel
the key lock function, hold the
FAST/LOCK(3s)/LOCAL key for 3 or more
seconds.
CAUTION
This key serves as the FAST, LOCK (3s), and
LOCAL keys. When putting the power supply into
the locked state, it will also automatically cancel
the FAST mode setting (if set) and restore the
power supply to the SLOW mode.
In the key-locked state, the OUTPUT key is still
functional so that the output can be turned off for
safety reasons.
