Boss Super Octave OC-3 Owner's Manual page 14

Troubleshooting
No sound / Low volume:
● Is the OC-3 properly connected to your
instrument?
Check the connection once more (p. 8).
● Is the volume turned down on any guitar
amp or effects device you have connected?
Check the settings of the connected device.
● Is DIRECT OUT connected?
Sounds are output only from the DIRECT
OUT jack when the effect is switched off
while a plug is connected to the DIRECT
OUT jack. When the effect is off, the out-
put from the OUTPUT (MONO) jack is
muted, with no sounds being output (p.
11).

Sound is distorted:
● Is the battery low?
As the battery is drained, the CHECK in-
dicator dims, and the OC-3 may start to
function incorrectly. 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.
● Could the level of the sound being input
be excessive?
With some guitars, distortion may be pro-
duced. Be careful of your guitar's output
level.
