Changing The Battery - Boss AC-3 Owner's Manual

Changing the Battery

When the indicator goes dim or no longer lights while an effect
is on, it means that the battery is nearly dead and must be
replaced. Replace the battery following the steps below.
* 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.

1. Loosen the thumbscrew at the front of the pedal,
then lift the pedal upwards to open the unit.
The thumbscrew can be left in the pedal while changing the
battery.
2. Remove the old battery from the battery housing,
and remove the snap cord connected to it.
3. Connect the snap cord to the new battery, and place
the battery inside the battery housing.
* Be sure to carefully observe the battery's polarity (+ versus -).
4. Slip the coil spring onto the spring base on the back
of the pedal, and then close the pedal.
* Carefully avoid getting the snap cord caught in the pedal, coil
spring, and battery housing.

hole and fasten it securely.
