Setting Up

This section contains information about setting up your EZ-250i for playing. Make sure to read
this section carefully before using the instrument.

Power Requirements

Although the EZ-250i will run either from an optional AC adaptor or batteries,
Yamaha recommends use of an AC adaptor whenever possible. An AC adaptor is
more environmentally friendly than batteries and does not deplete resources.
I Using an AC Power Adaptor • • • • • • • • • • • • • • • • • • • • • • • • •
q Make sure that the [STANDBY/ON] switch of the EZ-250i is set to
STANDBY.
w Connect the AC adaptor (PA-3C, PA-3B, or other adaptor specifically recom-
mended by Yamaha) to the DC IN 12V jack.
e Plug the AC adaptor into an AC outlet.

For battery operation the EZ-250i requires six 1.5V "D" size, LR20 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 and replace the batteries, as described below
q Open the battery compartment cover located on the instrument's bottom panel.
w Insert the six new batteries, being careful to follow the polarity markings in
the compartment cover.
e Replace the compartment cover, making sure that it locks firmly in place.

EZ-250i Owner's Manual
e
• Use ONLY a Yamaha PA-3C or
PA-3B AC Power Adaptor (or
other adaptor specifically rec-
ommended by Yamaha) to
power your instrument from
the AC mains. The use of other
adaptors may result in irrepa-
rable damage to both the adap-
tor and the EZ-250i.
• Unplug the AC Power Adaptor
when not using the EZ-250i, or
during electrical storms.
• Use only manganese or alka-
line batteries for this instru-
ment. Other types of batteries
(including rechargable batter-
ies) may have sudden drops of
power when battery power
becomes low, possibly result-
ing in loss of data in the flash
memory and the need to initial-
ize the flash memory.
• 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.
• If the instrument is not to be in
use for a long time, remove the
batteries from it, in order to
prevent possible fluid leakage
from the battery.
• The effective life of recharge-
able batteries may shorter than
that of conventional batteries.
