E01
MEMORY TROUBLE
The schedule and other data saved in the memory are broken down.
Check all set values.
The following are conceivable causes of loss or corruption of data
stored in memory.
・
Strong power noise and electrostatic noise
・
Faults in the supply voltage due to thunderbolts or lightning
conduction
・
Exceed in writing count limit of flash memory
It is convenient to write down set values in case of data corruption or
loss. (Use
11. Schedule Data Table
.)
Initialize the memory by turning the POWER switch ON while
pressing the MENU key. This resets all set values to the factory
values set before shipment. Re-set the values that you recorded on
paper beforehand.
If E01: MEMORY TROUBLE is displayed again, repair is required.
