* Inserting a plug into the INPUT Jack will automatically switch the unit on.
* 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, 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.
* 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.
