LINE CORD (15)
(120V products only)
For your safely, we have in¬
corporated a 3-wire line (mains)
cable with proper grounding
facilities. It is not advisable to
remove the ground pin under any
circumstances. If it is necessary to
use the equipment without proper
grounding facilities, suitable
grounding adaptors should be used.
Less noise and greatly reduced
shock hazard exists when the unit is
operated with the proper grounded
receptacles.
KEMOTE SWITCH JACK (16)
Provided for the connection of the
optional remote foots witch. Foot-
switch is used to select the Lead or
Normal channels and defeat reverb.
When using remote footswitch,
always insert the plug fully (second
click) to ensure proper operation.
