Power Requirements

Your PortaTone can run either on batteries (sold sepa-

rately) or on normal household current by using the

optional Yamaha PA-3/4/40 Power Adaptor.

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

Adaptor. Use of other AC adaptors could result in

damage to the instrument, so be sure to ask for the

right kind. Plug the adaptor into a convenient wall

outlet and its connector into the DC 10-12V IN jack on

the back of your PortaTone.

Using Batteries

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 illustration, making sure that

the positive and negative terminals are properly aligned.

Replace the lid.

Accessory Jacks

Using Headphones

For private practicing and playing without disturbing

others, connect a set of stereo headphones to the rear

panel HEADPHONES/AUX OUT jack. Sound from the

built-in speaker system is automatically cut off when

you insert a headphone plug into this jack.

Getting Started

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 or different types of batteries

(e.g., alkaline and manganese).

Auto Power OFF

The PSR-73 features an Auto Power OFF function that

automatically turns the power OFF if the instrument is

not used for approximately 30 minutes. This functions

whether batteries or the AC power adaptor is used.

HEADPHONES/

AUX OUT

DC IN 10-12V

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 HEADPHONES/AUX OUT

jack of the PortaTone.

The Music Stand

Insert the bottom edge of the music stand into the slot

located at the top rear of the PSR-73 control panel.
