Replacing Batteries; To Replace The Main Batteries - Casio CASSIOPEIA A-20 Service Manual & Parts List

REPLACING BATTERIES

The CASSIOPEIA has a dual power supply that consists of main batteries and a backup battery. Be sure to
load the main batteries and a back-up battery before using the CASSIOPEIA for the first time after purchas-
ing it. Also, replace batteries as soon as possible after they start to get weak.
Important!
• Never remove both the main batteries and the backup battery from the CASSIOPEIA at the same time.
If you do, data stored in memory can be corrupted or lost entirely.
• Whenever the main batteries and the backup battery both require replacement, be sure to replace the
main batteries first, before replacing the backup battery.
• Use two AA-size alkaline batteries or the optional rechargeable battery pack for the main power supply,
and a CR2032 lithium battery for the back-up power supply. Never use any other types of battery with
the CASSIOPEIA.
• Be sure to watch out for signs of low battery power. Replace main batteries as soon as possible after the
message shown below appears on the display.
"Your main batteries are running very low on power. Please change the batteries at your next opportu-
nity."
Replace the backup battery as soon as possible after the message shown below appears.
"Your backup battery is very low or missing. Data loss may result from failure to replace the battery very
soon."
Failure to replace batteries when they are low can result in corruption or loss of data stored in memory.
