Inserting and Replacing
Batteries

- Battery life of high-perform-
ance AA dry cells (R6P/
SUM-3) is approximately 1
hour (approximately 3 hours
when using LR6/AM-3).
Weakened batteries will cause
the transpose indicator to lose
its brightness and result in low-
er volume, poor tonal quality
and eventually the DH-500 will
switch OFF, even if you are
playing. If this occurs, replace

For total portability, the Digital Horn is designed so that you
can power it by using 6 AA-size dry cell batteries, or by using
standard household current through an optional AD-S AC
adaptor. You can also make use of car battery power by us-
ing CASIOs optional CA-S car adaptor.

Before inserting or replacing batteries, make sure that the
Digital Horn is turned OFF. Remove the battery compartment
cover by removing the screw holding it in place and insert
batteries, taking care the polarity (+/-) is correct. When
replacing batteries, be sure to replace all six to ensure long
battery life.

Using an AC Adaptor

< DH-500 terminals>

An AC adaptor (AD-5, optional) is required when using house-
hold current. Use only a genuine Casio AD-S adaptor with
the same voltage rating (100, 117, 220 or 240V) as the power
supply in your area to prevent damage to the Digital Horns
internal components. Plug the AC adaptor into the AC out-
let and the cord into the unit. This will automatically cut off
the battery power supply.

0 Use only genuine Casio adaptors to avoid risk of damage.

- The adaptor may become warm when left connected to an
outlet. This is normal, but the adaptor should be discon-
nected when not in use.
