DD-75 Owner’s Manual

Setting Up

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

Power Requirements

Although the instrument will run either from an AC adaptor

or batteries, Yamaha recommends use of an AC adaptor

whenever possible. An AC adaptor is more environmen-

tally friendly than batteries and does not deplete

resources.

Using an AC Adaptor

Make sure that the [ ] (Standby/On) switch is off, then

connect the AC adaptor in the order shown in the illustra-

tion.

Using Batteries

This instrument requires C size, Alkaline (LR14)/Manga-

nese (R14) batteries, or rechargeable nickel-metal hydride

batteries (rechargeable Ni-MH batteries). The Alkaline bat-

teries or rechargeable Ni-MH batteries are recommended

for this instrument, since other types may result in poorer

battery performance.

1 Make sure that the power of the instrument is off.

2 Open the battery compartment cover located on

the instrument’s bottom panel.

3 Insert the six new batteries, being careful to follow

the polarity markings on the inside of the compart-

ment.

4 Replace the compartment cover, making sure that

it locks firmly in place.

• Use only the specified AC adaptor (page 54). Using the

wrong AC adaptor can result in damage to the instrument

or overheating.

• When using the AC adaptor with a removable plug, make

sure to keep the plug attached to the AC adaptor. Using the

plug alone can cause electric shock or fire.

• Never touch the metallic section when attaching the plug.

To avoid electric shock, short circuit or damage, also be

careful that there is no dust between the AC adaptor and

plug.

• When setting up the product, make sure that the AC outlet

you are using is easily accessible. If some trouble or mal-

function occurs, immediately turn the power off and dis-

connect the plug from the outlet.

• Follow the order shown above in reverse when disconnecting

the AC adaptor/power cord.

WARNING

Plug

Slide the plug as indicated.

The shape of the plug differs

depending on your area.

CAUTION

NOTE

• Connecting or disconnecting the power adaptor with bat-

teries installed may turn the power off, resulting in loss of

data being recorded or transferred at the time.

• Make sure to set the battery type correctly (page 13).

• 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 with new ones or already

recharged ones.

• This instrument cannot charge the batteries. Use only an

appropriate charger device when charging.

• Power will be automatically drawn from the AC adaptor if an

AC adaptor is connected while batteries are installed in the

instrument.
