Changing The Battery - Boss Phase Shifter PH-3 Owner's Manual

Changing the Battery

When the CHECK 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.
* A battery was installed in the unit before it left the factory. The life
of this battery may be limited, however, since its primary purpose
was to enable testing. If operating this unit on batteries, please use
alkaline batteries.

1. Hold down the pedal and loosen the thumbscrew,
then open the pedal upward.
* The pedal can be opened without detaching the thumbscrew
completely.
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.
5. Finally, insert the thumbscrew into the guide bush
hole and fasten it securely.
