Troubleshooting
Power won’t come on /
CHECK indicator doesn’t light:
● Is the specified adaptor (PSA-series;
sold separately) properly connected?
Check the connection once more (p. 8).
* Never use any AC adapter other than one
specified for use with the AC-3.
● Is the battery low or dead?
Replace with a new battery (p. 16).
* The battery that was supplied with the unit is
for temporary use, intended primarily for
testing its operation.
* The use of an AC adaptor is recommended as
the unit's power consumption is relatively
high. Should you prefer to use batteries,
please use the alkaline type.
*
To prevent unnecessary battery consumption,
be sure to disconnect the plug from the INPUT
jack when not using the effects unit (
p. 6
).
● Is your guitar properly connected to the
INPUT jack?
Check the connection once more (p. 8).
* The power is switched on only when a cable is
plugged in to the INPUT jack.
* The CHECK indicator shows whether the
effect is being applied or not. It does not
indicate whether the power to the device is on
or not.
Sound is distorted:
● Is the battery low?
As the battery is drained, the CHECK in-
dicator dims, and the AC-3 may start to
function incorrectly. Replace with a new
battery (p. 16).
