Setting Up
This section contains information about setting up your DD-35 for playing. Make
sure to read this section carefully before using the instrument.
Although the DD-35 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.
q Make sure that the [STANDBY/ON] switch of the DD-35 is set to
STANDBY.
w Connect the AC adaptor (PA-3B or other adaptor specifically rec-
ommended by Yamaha) to the power supply jack.
e Plug the AC adaptor into an AC outlet.
• Use ONLY a Yamaha PA-3B AC Power Adaptor (or other adaptor spe-
cifically 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 DD-35.
• Unplug the AC Power Adaptor when not using the DD-35, or during
electrical storms.
For battery operation the DD-35 requires six 1.5V “AA” size, R6P
(LR6) or equivalent batteries. (Alkaline batteries are recommended.)
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 on the inside of the compartment.
e 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 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 bat-
tery.
• Plugging or unplugging the AC power adaptor while the batteries are
installed will reset the DD-35 to the defaults.
