Note
If the unit is turned off and the display disappears, it
cannot be operated with the card remote commander
unless (SOURCE) on the unit is pressed, or a disc is
inserted to activate the unit first.
Replacing the lithium battery
Under normal conditions, the battery will last
approximately 1 year. (The service life may be
shorter, depending on the conditions of use.)
When the battery becomes weak, the range of the
card remote commander becomes shorter.
Replace the battery with a new CR2025 lithium
battery. Use of any other battery may present a
risk of fire or explosion.
Notes on the lithium battery
• Keep the lithium battery out of the reach of children.
Should the battery be swallowed, immediately
consult a doctor.
• Wipe the battery with a dry cloth to assure a good
contact.
• Be sure to observe the correct polarity when
installing the battery.
• Do not hold the battery with metallic tweezers,
otherwise a short-circuit may occur.
WARNING
Battery may explode if mistreated.
Do not recharge, disassemble, or dispose of
in fire.
