Setting Up

Setting Up
Be sure to do the following operations BEFORE turning on the power.

Power Requirements

Although the instrument 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.
Using an AC Power Adaptor
1 Make sure that the [
instrument is in the "Standby" position.
WARNING
• Use the specified adaptor (page 86). The use of other
adaptors may result in irreparable damage to both the
adaptor and the instrument.
2 Connect the AC adaptor to the power supply jack.
3 Plug the AC adaptor into an AC outlet.
CAUTION
• Unplug the AC Power Adaptor when not using the
instrument, or during electrical storms.

Using Batteries
1 Open the battery compartment cover located on the
instrument's bottom panel.
2 Insert the six new batteries, being careful to follow
the polarity markings on the inside of the compart-
ment.
3 Replace the compartment cover, making sure that it
locks firmly in place.
NOTE
• Connecting the AC power adaptor automatically supplies
power from the adaptor and overrides battery power, even
when batteries are installed.

For battery operation the instrument requires six 1.5V
"AA" size, LR6 or equivalent batteries. (Alkaline bat-
teries are recommended.) When battery power becomes
too low for proper operation, make sure to replace all
batteries, following the precautions listed below.
If necessary, also make sure to save all important User
data (see pages 50, 77).
CAUTION
• Be sure to install the batteries in the same direction, main-
taining the correct polarity (as shown). Incorrect battery
installation may result in heat, fire and/or leaking of corro-
sive chemicals.
• When the batteries run down, replace them with a com-
plete set of six new batteries. NEVER mix old and new bat-
teries. Do not use different kinds of batteries (e.g. alkaline
and manganese) at the same time.
• If the instrument will not be used for an extended period of
time, remove the batteries to prevent possible fluid leakage.
NOTICE
• Use only manganese or alkaline batteries for this instru-
ment. Other types of batteries (including rechargeable bat-
teries) may exhibit a sudden drop in power when the
batteries are low, possibly resulting in a loss of flash mem-
ory data.
• Please use the power adaptor when transferring data to
flash memory. Batteries (including rechargeable types) can
be drained rapidly by this type of operation. If the batteries
do become drained during a data transfer, both the data
being transferred and the data currently in the transfer des-
tination will be lost.
