* Changes in settings in the User mode
(2) Switch off the power, remove the IC 18, ROM, and battery, and then remove the Main PCB.
(3) Install the removed IC 18, ROM, and battery to a new Main PCB, and install that Main PCB in the
main unit.
(4) Start test mode.
(5) Execute Test Modes Nos. 080 (Clear Error-Status Data), 081 (Clear User Memory), and 082 (Clear
