SELECTING AN EFFECT/MEMORY LOCATION
1. Effects and memory locations can only be selected when
the utility mode is not active (the UTILITY KEY indicator
is not lit). If the UTILITY key indicator is lit. press and
hold the UTILITY key until its indicator goes out and the
utility mode is exited.
2. Press the program select or
key to increment or
decrement the memory location number shown on the LED
display. Hold either of these keys down for continuous
incrementing or decrementing. The name of the program
corresponding to the currently selected memory location
will be shown on the LCD. Note that at this stage the LED
memory number display is flashing, indicating that
although a new location has been selected. its contents
have not yet been recalled.

3. When the desired memory location/effect has been
selected. press the RECALL key. The LED memory
number display will stop flashing and the selected effect
will be engaged.
BYPASSING THE EFFECT
There are two ways to switch the selected effect in and out: 1)
with the control panel BYPASS switch and 2) with a
footswitch connected to the connector-panel BYPASS
footswitch jack. An optional Yamaha FC5 Footswitch can be
used for foot-bypass control. In either case – when the
control-panel BYPASS key or BYPASS footswitch is pressed
-the LED in the BYPASS key will light to indicate that the
selected program is currently being bypassed and the input
signal is directly routed to the output terminals (i.e. the effect
is OFF). Press the BYPASS key or footswitch a second time
to turn off the BYPASS Key LED and turn the effect back
ON.
