PREPARATION FOR USE
POWER SOURCES
This player is designed to operate on one alkaline “AAA” batteries, not 
included. Attempting to operate this unit on any other power source 
may cause damage to the unit and such damage is not covered by 
your warranty.
INSTALLING THE BATTERIES
The battery compartment is located on the top of the cabinet.
1.) Slide the battery compartment cover outward, and then up.
2.) Insert one fresh “AAA” alkaline battery in the 
battery compartment. Be sure to follow the polarity 
marking in the battery compartment. If the battery 
is inserted incorrectly the unit will not work.
3.) Push down on the battery compartment cover,
and then slide inward to close.
WHEN TO CHANGE THE BATTERY
When the battery is getting weak, the indicator 
changes from “ 
” (full battery) to “
” (replace
battery) in the display, the batteries are almost 
exhausted and should be changed as soon as 
possible. Do not leave weak or exhausted batteries 
in the player as they will eventually leak and cause 
corrosion inside the battery compartment.
