Getting Started - Yamaha PSR-75 portatone Product Manual

Getting Started

Power Requirements
Your PortaTone can run either on batteries
(sold separately) or on normal household
current by using one of the optional Yamaha
PA-3/4/40 Power Adaptors.
Using an AC Power Adaptor
To connect your PortaTone to a wall socket,
you will need the optionally available
Yamaha PA-3/4/40 Power Adaptors. Use of
other AC adaptors could result in damage
to the PortaTone and/or Power Adaptor, so
be sure to ask for the right kind. Plug the
adaptor into a convenient wall socket and its
connector into the DC 9-12V IN jack on the
back of your PortaTone.
Inserting Batteries
Turn the instrument upside-down and remove
the battery compartment lid. Insert six 1.5-
volt size "D" batteries as shown in the illus-
tration, making sure that the positive and
negative terminals are properly aligned.
Replace the lid.
When the Batteries Run Down
When the batteries run low and the battery voltage
drops below a certain level, the PortaTone may
not sound or function properly. As soon as this
happens, replace them with a complete set of six
new batteries. NEVER mix old and new batteries.
Accessory Jacks
Using Headphones
For private practicing and playing without disturb-
ing others, connect a set of stereo headphones to
the rear panel HEADPHONES/AUX. OUT jack.
Sound from the built-in speaker system is auto-
matically cut off when you insert a headphone
plug into this jack.
Connecting a Keyboard
Amplifier or Stereo System
After making sure the PortaTone and any external
devices are turned off, connect one end of a stereo
audio cable to the LINE IN or AUX. IN jack(s) of
the other device and the other end to the HEAD-
PHONES/AUX. OUT jack of the PortaTone.
