2.3 Replacement of Fuse
A fuse at the rear of the main unit protects the equipment from overcurrent and equipment fault.
If the power cannot be turned on, the fuse may have blown.
2.4 Backup Battery
The manganese lithium battery inside the main unit is used to keep the clock running, and its life
is about five years. When the battery voltage is low the time is “slow.” Have a qualified technician
replace the battery when this occurs.
2.5 Clearing the RAM
The RAM stores frequency data of fax transmitting stations throughout the world. If part of the
RAM was deleted in error, the data for fax transmitting stations can be retrieved from the ROM. In
this case it is necessary to clear the RAM. Be sure that it is all right to clear the RAM as all data
(frequency, etc.) stored there will be deleted.
1. Press the PRG key followed by the 9 key.
2. Press the E key to clear the RAM.
3. Press the C key to return to the standby display.
Note: Do not confuse RAM error with keyboard lockup. The keyboard may lock if some abnormal
operation is detected. If this occurs, turn the power off and on again.
