Boss Super Octave OC-3 Owner's Manual page 9

* When running the unit on battery power, inserting a plug into the GUITAR IN or BASS IN
Jack will automatically switch the unit on.
* 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 malfunction and/or damage to speakers or other devices, always turn down the
volume, and turn off the power on all devices before making any connections.
* If there are batteries in the unit while an AC adaptor is being used, normal operation will
continue should the line voltage be interrupted (power blackout or power cord disconnection).
* Once the connections have been completed (p. 8), turn on power to your various devices in
the order specified. By turning on devices in the wrong order, you risk causing malfunction
and/or damage to speakers and other devices.
When powering up:
When powering down:
* Always make sure to have the volume level turned down before switching on power. Even
with the volume all the way down, you may still hear some sound when the power is switched
on, but this is normal, and does not indicate a malfunction.
* When operating on battery power only, the unit's indicator will become dim when battery
power gets too low. Replace the battery as soon as possible.
Turn on the power to your guitar amp last.
