Preparation

This section contains information about setting up your PSR-410 and preparing to play.
Be sure to go through this section carefully before using your PSR-410.

Power Supply

Your PSR-410 will run either from an optional power adaptor or batteries*. Follow the instructions below
according to the power source you intend to use.

For battery operation the PSR-410 requires six 1.5V SUM-l, "D" size, R-20 or equivalent batteries.
When the batteries need to be replaced the volume may be reduced, the sound may be distorted, and other
problems may occur. When this happens, turn the power off while either the batteries are replaced or an AC
adaptor is connected.
* When batteries are used the sound of the PSR-410 may be distorted at high volume
levels. This is because the power of the amplifier is reduced when batteries are used.
•
Never interrupt the power supply (e.g. remove the batteries or un-
plug the AC adaptor) during any PSR-410 record operation! Doing so
can result in a loss of data.
Plug the DC output cable from an optional Yamaha PA-3, PA-4, PA-5, or
PA-40 AC Power Adaptor into the DC IN jack on the rear panel of the PSR-
410, then plug the Power Adaptor (or the AC cable of the Power Adaptor) into
a convenient wall AC power socket. The internal batteries are automatically
disconnected when an AC Power Adaptor is used.
•
Use ONLY a Yamaha PA-3, PA-4, PA-5, or PA-40 AC Power Adaptor
to power your instrument from the AC mains. The use of other adap-
tors may result in irreparable damage to both the adaptor and the
PSR-410.
•
Using the PA-5 with the PSR-410 will provide a slight increase in the
overall volume.
When the batteries fail, replace them as follows:
Open the battery compartment cover located on the instrument's bottom
panel.
Insert the six new batteries, being careful to follow the polarity markings on
the inside of the compartment.
Replace the compartment cover, making sure that it locks firmly in place.
•
When the batteries run down, replace them with a complete set of
six new batteries. NEVER mix old and new batteries.
• Do not use different kinds of batteries (e.g. alkaline and manganese)
at the same time.
• To prevent possible damage due to battery leakage, remove the bat-
teries from the instrument if it is not to be used for an extended pe-
riod of time.
