Insert a battery into a RAM Memory Card before mounting the Card into the
CPU. Leave the battery in its holder. Battery life expectancies at 20_C are given
below. Replace the battery within the time listed. Refer to Section 5 Inspection
and Maintenance for the battery replacement procedure.
The lithium battery in RAM Cards can burn or explode if it is shorted, crushed, or
heated to more than 100_C. Dispose of the Memory Card properly.
Data contained in the ROM Card is stored on EPROM chips and cannot be al-
tered or erased during the CPU’s operation. The EPROM chip is mounted to the
Memory Card and the entire pack is installed in the CPU. Once data is written to
the chip, the data will not be lost when the power to the PC is OFF.
ROM Cards are shipped unprogrammed. The ROM Card can be programmed
using a CV500-MCWjj Memory Card Writer.
The procedure for erasing EPROM Memory Card data is as follows:
