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).
