The optical output is set ON or OFF. The illuminated key is located on the front
panel of the unit.
Operation Remarks
Press the Opt. On key.
Every time the Opt. On key is pressed, the mode switches ON and OFF alternately.
When the light is output, the Opt. On key remains lit. Even when the mode is set
ON, if a safety device such as remote interlock is working to shade light, the key
flickers.
When the mode is set OFF, the key is unlit.
POINT
The MT9812B incorporates the remote interlock con-
nector and optical output modifier key as light safety
devices to be used when the light source is used. Un-
less the remote interlock connector is in the state of
short circuit or the optical output modifier switch is
ON, no light will be output even if the optical output key
is switched ON.
See “3.5 Connection of Remote Interlock Connector”
for more information on how to use the remote inter-
lock connector.
