This unit has a replaceable battery.
To access the battery compartment, turn the unit over and
rest it on a soft surface.
Remove the screw that secures the battery door and lift
the door off. The battery rests inside a bracket within the
opening.
It is OK to use an alkaline, cabon-zinc, lithium, or
rechargeable battery.
After servicing the battery, immediately replace the
battery door to avoid misplaced parts.
** To prevent damage from corroded / leaking batteries, always remove the battery before putting the unit in storage.
Battery installation and replacement
The power is on whenever a cable is plugged in to the 1/4” audio output jack.
To save battery life, unplug the audio output cable when the unit is not in use. (This is not necessary while an AC adapter is connected)
Using an AC adapter
This unit requires a BOSS-type AC adapter with 9 volts DC
output and tip negative polarity.
Its current requirement is only 15mA, and it is OK to share
power with other FX pedals using a daisy-chain cable.
It is protected against reverse polarity and overvoltage.
If the LEDs don’t ash after connecting an AC adapter:
Be sure a mono-type cable is plugged in to Audio Out
Verify the AC adapter has tip-negative polarity
Check for damage to the AC adapter cable
Using a daisy-chain power cable (not included)
