Operation

Overview

Insert a 9V battery (2) or connect a regulated 9V power supply adaptor to the DC jack (4).
Connecting a cable to the jack (3) will automatically switch the unit on.
Pressing the pedal (1) switches the unit on or off.
Instead of using this unit on the frontstage, you can place it with your equipment and control it with a standard momentary footswitch connected to the remote jack (7).
Before changing the battery (2) always unplug the jack (3) to switch the unit off.
We suggest to use a regulated 9V power supply adaptor to keep our environment clean.
Power supply specifications: see imprint on bottom of unit.
- Thank you.

Avoid using this unit in extreme humidity, heat or dust environment.
When the unit is not in use for longer periods, remove the battery (2) to prevent damages by battery leakage.
Also unplug the jack (3) to prevent wasting battery life when the unit is not in use.
