Troubleshooting - Boss Super Octave OC-3 Owner's Manual

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 OC-3.
● Is the battery low or dead?
Replace with a new battery (p. 12).
* The battery that was supplied with the unit is for
temporary use, intended primarily for testing its
operation. For extended use, we suggest replacing it
with an alkaline battery.
● Is your guitar (or bass) properly connect-
ed to the GUITAR IN (or BASS IN) jack?
Check the connection once more (p. 8).
* To prevent useless depletion of the battery when the
unit is running on battery power, the power is
switched on only when a cable is plugged in to the
GUITAR IN or BASS IN 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.
