EPS-J6 PLUS Test Procedure
EPS-16
PLUS
TEST PROCEDURE
The
following procedure will ensure the thorough testing
of
the EPS-16 PLUS and
also
will aid
in
troubleshooting
the
unit
To
do the following tests you will need a
M1DI
cable, a
Dual
Footswitch
(model
SW-5),
and
a Control Voltage Pedal (model CVP-l). The EPS-16 PLUS should be
connected to a sound system in stereo.
If
it
is
not
known
whether the KeypadlDisplay board is good, it can cause confusion
in
tracking
down the problem.
If
