Getting Started; Setting Up The Power Supply; Hook-Up Terminals For Attachments - Yamaha PortaSound PSS-790 Owner's Manual

Getting Started
a. Setting up the power supply
The PSS-790 can be operated using either batteries or a
standard outlet.
a) When you are using batteries
Flip the PSS-790 over and open the battery case. Insert six
batteries (dry cells: 1.5V SUM-2 or R-14) all facing the
same direction as shown. Replace cover.
* In case batteries' voltage are low, you hear the sounds distorted. If you
go on using the PortaSound, <bt chn> indication will be shown. In this
case, it's the time to replace all of 6 batteries with new ones.
* Do not use the batteries of different types other than listed above.
b) When using an electrical outlet
An authorized optional AC adaptor (YAMAHA PA-3, PA-4 or
PA-40) must be used. The adaptor is plugged into the DC
9-12V IN terminal located on the back of the instrument.
* There are different types of AC adaptors, be careful to use only the
models mentioned above.
* |f you leave the instrument without any power supply (batteries or
adaptor) for a long period, your record in the Song Memory (explained
later) will be lost, and the PSS-790 will be in the original status when
shipped. But you don't mind the amount of time for changing batteries —
1 minute at most. This short period will not cause this to occur.
b. Hook-up terminals for
attatchments
To use headphones: Plug the jack of the headphones into
the terminal marked HEADPHONES/AUX. OUT. When the
jack is plugged in, the speakers will no longer play out ,
thereby enabling you to enjoy making music without
disturbing those around you.
To connect to keyboard amplifier or stereo: ( in using a
keyboard or stereo amplifier you will enhance greatly the
overall sound) Plug in an Audio connection cord from the
PSS-790's HEADPHONES/AUX. OUT terminal to the
keyboard or stereo amplifier's LINE IN, AUX IN, etc.
"рд
* Before inserting plugs in, MAKE SURE the volume controls on the
amplifiers are turned all the way down to prevent damage to the
speakers.
Note: In both cases of attatchments (headphones and
amplifiers), the Master Volume control located on the PSS-
790 can be used in controlling levels of volume.
