6.2 Precautions for Memory and Battery Replacement
(1) Precautions for memory replacement
(a) Copying programs into the ROM
The ROM memory is not required for the Universal model QCPU because the program memory is
the flash ROM.
(b) Using the file register
When the existing CPU module is replaced with the Q00UJCPU, the file register cannot be used
because the standard RAM is not built in the Q00UJCPU.
To use the file register, select the Q00UCPU.
(2) Precautions for battery replacement
Replace the A Series battery (A6BAT*) with a Q Series battery (Q6BAT, Q7BAT).
(The Q series CPU module comes with the Q6BAT as standard.)
Refer to the user's manuals of each CPU module regarding battery life because it varies depending on
the type of CPU module.
* The A6BAT is not a model to be discontinued.
