Note:
The SRAM card is supplied power by the main battery when it is installed in the main unit.
This means that the SRAM card can be used normally as long as it is in the slot, even if the
voltage of the card battery is zero.
In this case, however, the data on the SRAM card will be lost when the card is removed from the
main unit slot. Since the Casio SRAM card is provided with two batteries, the data will not be
lost a short while even if one of them is removed. However, it is recommended that the SRAM
card battery be replaced only after making a backup of the data to avoid accidental loss.
Main Battery Recharge
The main battery can be recharged using either of the following methods:

Recharging with the charger
According to the "Main battery replacement" procedure described on the previous page, remove
the main battery and place it on the charger.

Recharging with the AC adaptor
While keeping the main battery to be recharged in the main unit, insert the AC adaptor plug in
the charging jack located on the side of the main unit. This starts the recharging operation.

Recharging with the I/O Box
If the main unit is mounted on the I/O Box while the main battery to be recharged is in the main
unit, the charging operation starts.
