A-4. CPU Circuit Board
(Time required: About 7 minutes)
A-4-1. Open the control panel U7 assembly and secure with
the service stays. (See procedure 1)
A-4-2. Remove the four (4) screws marked [990]. The CPU
circuit board can then be removed. (Photo 11)
*
IC204 on CPU circuit board: MRAM (Magneto resistive
Random Access Memory) is a storage element using
magnetism. Keep any magnetic item such as a screwdriver
away from it as the magnetic force of such item may cause
damage to the data of IC204 and the IC itself.
*
MAC (Media Access Control) address is stored in the
CPU circuit board. If the CPU circuit board is replaced,
MAC address will be changed.

(Time required: About 7 minutes)
A-5-1. Open the control panel U7 assembly and secure with
the service stays. (See procedure 1)
A-5-2. Remove the four (4) screws marked [1010]. The FX
circuit board can then be removed. (Photo 11)
