Setting Up This section contains information about setting up your PSR-620 and preparing to play. Be sure to go through this section carefully before using your PSR-620. Power Supply Your PSR-620 will run either from batteries or an optional power adaptor. Follow the instructions below according to the power source you intend to use. s Using An Optional AC Power Adaptor Plug the DC output cable from an optional Yamaha PA-5, PA-5B, or PA5C AC Power Adaptor into the DC IN jack on the rear panel of the PSR620, 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.

Doing so can result in a loss of data. • Use ONLY a Yamaha PA-5, PA5B, or PA-5C AC Power Adaptor to power your instrument from the AC mains. The use of other adaptors may result in irreparable damage to both the adaptor and the PSR-620. s Using Batteries ...For battery operation the PSR-620 requires six 1.5V SUM-1, "D" size, R-20 or equivalent batteries.

Power Supply
Your PSR-620 will run either from batteries or an optional power adaptor.
Follow the instructions below according to the power source you intend to use.
•
Never interrupt the power
supply (e.g. remove the batter-
ies or unplug the AC adaptor)
during any PSR-620 record
operation! Doing so can result
in a loss of data.
■
Using Batteries
...............................................................................................................................................
For battery operation the PSR-620 requires six 1.5V SUM-1, “D” size,
R-20 or equivalent batteries.
When the batteries need to be replaced “Btry Low” will appear on the
display. Also the volume may be reduced, the sound may be distorted, and
other problems may occur. When this happens, turn the power OFF and ei-
ther replace the batteries or connect an AC adaptor.
Replace the batteries as follows:
Z
Open the battery compartment cover located on the instrument’s bottom
panel.
X
Insert the six new batteries, being careful to follow the polarity markings
on the inside of the compartment.
C
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 batter-
ies.
•
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 batteries from the instru-
ment if it is not to be used for
an extended period of time.
Setting Up
This section contains information about setting up your PSR-620
and preparing to play. Be sure to go through this section carefully
before using your PSR-620.
•
Use ONLY a Yamaha PA-5, PA-
5B, or PA-5C AC Power Adap-
tor to power your instrument
from the AC mains. The use of
other adaptors may result in
irreparable damage to both the
adaptor and the PSR-620.

Using An Optional AC Power Adaptor
.............................................................
Plug the DC output cable from an optional Yamaha PA-5, PA-5B, or PA-
5C AC Power Adaptor into the
DC IN
jack on the rear panel of the PSR-
620, then plug the Power Adaptor (or the AC cable of the Power Adaptor)
into a convenient wall AC power socket. The internal batteries are automati-
cally disconnected when an AC Power Adaptor is used.
