Caution:
1. When the batteries run down, replace them with a complete set of six new bat-
teries. NEVER mix old and new batteries.
2. To prevent possible damage due to battery leakage, remove the batteries from
the instrument if it is not to be used for an extended period of time.
9 Using An Optional Power Adaptor
Plug the DC output cable from an optional PA-1, PA-1B or PA-3 Power Adap-
tor into the DC(9-12V)IN jack on the rear panel, then plug the adaptor into a
convenient wall AC power socket.
Use ONLY a Yamaha PA-1, PA-1B or PA-3 Power Adaptor to power your in-
strument from the AC mains. Attempting to use other AC adaptors could result
in serious damage to your PSR-2.
Using Headphones or an External
Sound System
The Rear-panel HEADPHONES/AUX. OUT Jack H
A standard pair of stereo headphones can be plugged in here for private practice
or late-night playing. The internal speaker system is automatically shut off when
a pair of headphones is plugged into the HEADPHONES/AUX. OUT jack. The
HEADPHONES/AUX. OUT jack can also be used to deliver the output of the
PSR-2 to a keyboard amplifier, stereo sound system, mixing console or tape
recorder. Use the optional Yamaha connecting cord to connect the HEAD-
PHONES/AUX. OUT jack to your sound system.
