DGX-505/305 Owner’s Manual
Setting Up
Make sure to do the following operations BEFORE turning on the power.
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
ᕡ
Make sure that the [STANDBY/ON] switch of the
instrument is set to STANDBY.
ᕢ
Connect the AC adaptor (PA-5D, PA-5C or other
adaptor specifically recommended by Yamaha) to the
power supply jack.
ᕣ
Plug the AC adaptor into an AC outlet.
■ Using Batteries
ᕡ Open the battery compartment cover located on the
instrument’s bottom panel.
ᕢ Insert the six new batteries, being careful to follow
the polarity markings on the inside of the compart-
ment.
ᕣ Replace the compartment cover, making sure that it
locks firmly in place.
For battery operation the instrument requires six 1.5V
“D” size, R20P (LR20) or equivalent batteries. (Alkaline
batteries are recommended.) When battery power
becomes too low for proper operation, a “LOW BAT-
TERY!!” message flashes in the upper right of the dis-
play. As soon as this message appears, make sure to
replace all batteries, following the precautions listed
below.
If necessary, also make sure to save all important User
data (see pages 49 and 75), since custom panel set-
tings are lost when the batteries are removed.
Power Requirements
• Use ONLY a Yamaha PA-5D, PA-5C AC Power Adaptor (or other
adaptor specifically recommended by Yamaha) to power your
instrument from the AC mains. The use of other adaptors may
result in irreparable damage to both the adaptor and the
instrument.
WARNING
• Unplug the AC Power Adaptor when not using the instrument,
or during electrical storms.
CAUTION

ᕣ
• Connecting the AC power adaptor automatically supplies power from
the adaptor and overrides battery power, even when batteries are
installed.
NOTE
• Use only manganese or alkaline batteries for this instrument.
Other types of batteries (including rechargeable batteries) may
have sudden drops of power when battery power becomes low,
possibly resulting in loss of data in the flash memory / SmartMe-
dia™ card and the need to re-format the card.
• Make sure to install the batteries in the same direction, maintain-
ing the correct polarity (as shown). Incorrect battery installation
may result in heat, fire and/or leaking of corrosive chemicals.
• 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.
• If the instrument is not to be in use for a long time, remove the bat-
teries from it, in order to prevent possible fluid leakage from the
battery.
• Please use the power adaptor when transferring data to SmartMe-
dia or 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 trans-
ferred and the data currently in the transfer destination will be
lost.
CAUTION
• Don’t open the battery compartment cover while the instrument is
resting on the keyboard stand. The batteries can fall out of the bat-
tery compartment and possibly cause damage. Always turn the
instrument over before opening the battery compartment cover.
