1. ENTRY INTO THE MAINTENANCE MODE
To make the facsimile equipment enter the maintenance mode, press the Function ,
* , 2 , 8 , 6 , and 4 keys in this order.
Within 2 seconds
The equipment beeps for approx. 3 seconds and displays "MAINTENANCE" on the LCD, in-
dicating that it is placed in the initial maintenance mode, a mode in which the equipment is
ready to accept entry from the keys.
To select one of the maintenance-mode functions listed in Section 2, enter the corresponding
2-digit function code with the numerical keys on the control panel. (The details of each main-
tenance-mode function are described in Section 3.)
NOTES:
• Pressing the 9 key twice in the initial maintenance mode restores the equip-
ment to the standby state.
• Pressing the Stop button after entering only one digit restores the equipment
to the initial maintenance mode.
• If an invalid function code is entered, the equipment resumes the initial mainte-
nance mode.
