Since the memory cassette and pin connector are made of resin, do not drop them or
apply heavy impact to them.
Do not remove the printed-circuit board of memory cassette from the case. Doing so
could give damage to the module.
Carefully prevent foreign matter such as wire chips from entering the inside of the
memory cassette.
If it does get inside the module, remove it immediately.
When installing the memory cassette into the CPU module, fully press it to the
connector.
Do not place the memory cassette on a metal object where current is or can be
leaked, or materials like wood, plastic, vinyl, fibers, electric wires or paper where
static electricity is charged.
Do not touch the lead of the memory. This may damage the memory.
Do not touch the CPU connector of the memory cassette. Doing so may cause poor
contact.
POINT
(1) Before installing the memory cassette to or removing it from the CPU module,
make sure that the power is OFF. Installing or removing the memory cassette
with power ON destroys its memory.
(2) Install the memory cassette and turn on the power supply of CPU module.
RAM memory built-in CPU module (parameter, T/C setting value, main
program) is overwritten.
If the RAM memory is needed, back up the data using a peripheral device
before installing the memory cassette.
