Yamaha PortaTone PSR-400, Owner'S Manual

Page: 6 / 48

Using An Optional AC Power Adaptor
Plug the DC output cable from an optional Yamaha PA-5 AC Power Adaptor
into the DC IN jack on the rear panel of the PSR-400/PSR-500, then plug the AC
cable of the Power Adaptor into a convenient wall AC power socket.
The internal batteries are automatically disconnected when an AC Power Adap-
tor is used.
• Use ONLY a Yamaha PA-5 AC Power Adaptor to power your instrument from the AC mains.
Other adaptors may be damaged by use with the PSR-400/PSR-500, and they may even
cause serious damage to your PSR-400/PSR-500.

Caution:
1. When the batteries run down, replace them with a complete set of six new batteries.
NEVER mix old and new batteries.
2. Do not use different kinds of batteries at the same time
.
3. To prevent possible damage due to battery leakage, remove the batteries from the instru-
ment if it is not to be used for an extended period of time.
* If fresh batteries or an AC adaptor are not immediately available, it may be possible to use
the PSR-400/PSR-500 for a little while longer by turning the power off and then on again,
and playing at a low volume setting.
Using Batteries
The PSR-400/PSR-500 is initially supplied with a set of batteries. Depending on
storage conditions, the supplied batteries may not last as long as a fresh set.
When the batteries need to be replaced, "batt" will appear on the MULTI DIS-
PLAY. When this display appears the PSR-400/PSR-500 will not operate, and the
power must be turned off while either the batteries are replaced or an AC adaptor is
connected.* Internal data will be retained for up to about 10 minutes while the
batteries are changed or an AC adaptor is connected.
When the batteries fail, replace them with six 1.5V SUM-1, "D" size, R-20 or
equivalent batteries, as follows:
1 . Open the battery compartment cover located on the instrument's bottom panel
and remove the old batteries.
2. Insert the six new batteries, being careful to follow the polarity markings on the
inside of the compartment.
3. Replace the compartment cover, making sure that it locks firmly in place.
Your PSR-400 or PSR-500 will run either from batteries* or an optional power
adaptor. Follow the instructions below according to the power source you intend to
use.
* When batteries are used the sound of the PSR-400/PSR-500 may be distorted at high vol-
ume levels. This is because the power of the amplifier is reduced when batteries are used.
CAUTI0N!
Never interrupt the power supply (e.g. remove the batteries or unplug the AC adaptor) dur-
ing any PSR-400/PSR-500 record operation! Doing so can result in a loss of data.
This section contains information about setting up your PSR-
400/PSR-500 and preparing to play. Be sure to go through this
