DD-65/YDD-60 Owner’s Manual
Setting Up
Be 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 recom-
mends use of an AC adaptor whenever possible. An AC adaptor is more environmentally friendly
than batteries and does not deplete resources.
q
Make sure that the power of the instrument
is off (display shows no indications).
• Use the specified adaptor (PA-5D, PA-150, or an equivalent
recommended by Yamaha) only. The use of other adaptors
may result in irreparable damage to both the adaptor and the
instrument.
w
Connect the AC adaptor to the power supply jack.
e
Plug the AC adaptor into an AC outlet.
• Unplug the AC Power Adaptor when not using the instru-
ment, or during electrical storms.
• Never interrupt the power supply (e.g. remove the batteries
or unplug the AC adaptor) during any DD-65/YDD-60 record
operation! Doing so can result in a loss of data.
• Even when the instrument is turned off, electricity is still
flowing to the instrument at the minimum level.
When you are not using the instrument for a long time, make
sure you unplug the AC power adaptor from the wall AC out-
let.
q
Open the battery compartment cover located
on the instrument’s bottom panel.
w
Insert the six new alkaline batteries, being
careful to follow the polarity markings on
the side of the compartment.
e
Replace the compartment cover, making
sure that it locks firmly in place.
• Never connect or disconnect the AC power adaptor when the
power is on and the batteries are installed. Doing so will turn
the power off.
For battery operation the instrument requires six 1.5V
“C” size, LR14 or equivalent batteries. (Alkaline bat-
teries are recommended.) When battery power
becomes too low for proper operation, the volume
may be reduced, the sound may be distorted, and
other problems may occur. When this happens, make
sure to replace all batteries, following the precautions
listed below.
• Use alkaline batteries for this instrument. Other types of bat-
teries (including rechargeable batteries) may have sudden
drops of power when battery power becomes low.
• Make sure to install the batteries with the proper orientation,
maintaining 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 complete
set of six new batteries. NEVER mix old and new batteries.
Do not use different kinds of batteries (e.g. alkaline and man-
ganese) 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 leak-
age from the battery.
