Page: 3 / 28

Getting Started
Power Requirments
Your PortaTone can run either on batteries (sold
separately) 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.

Connecting a Keyboard Amplifier
or Stereo System
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 batter-
ies. Never mix old and new or different types of
batteries (e.g., alkaline and manganese).
Auto Power OFF
The PSR-185/77 features an Auto Power OFF func-
tion 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.
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.
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-185/77 control
panel.
