20 February, 2001 INSTALLATION REQUIREMENTS
1. INSTALLATION
NOTE: 1) Never install telephone wiring during a lightning storm.
2) Never install telephone jacks in wet locations unless the jack is
specifically designed for wet locations.
3) Never touch uninsulated telephone wires or terminals unless the
telephone line has been disconnected at the network interface.
4) Use caution when installing or modifying telephone lines.
5) Avoid using a telephone (other than a cordless type) during an electrical
storm. There may be a remote risk of electric shock from lightning.
6) If there is a gas leak, do not use the telephone in the vicinity of the leak
to report it.
!
CAUTION
1. Before installing the fax unit, switch off the main power and operation
switches, and disconnect the power cord.
2. The fax unit contains a lithium battery. The danger of explosion exists if
a battery of this type is incorrectly replaced. Replace only with the same
or an equivalent type recommended by the manufacturer. Discard used
batteries in accordance with the manufacturer’s instructions.

4.2 FAX SC CODES
4.2.1 OVERVIEW
If bit 7 of System Switch 1F is at the default setting, when the FCU detects a Fax
SC Code condition other than SC1201, it resets itself automatically. This initializes
the FCU without erasing files in the SAF memory or resetting the switches.
klqbW=
klqbW= For details on Fax SC Code 1201, refer to the following section.
klqbW=klqbW=
If bit 7 of System Switch 1F is changed to “1”, when the FCU detects any Fax SC
Code condition (not only SC1201), it displays the code on the display and stops
working until the fax unit is initialized us ing one of the following methods:
• Hold down the “#” and “*” keys for mo re than 10 s.
• Turn off the main power switch and turn it back on.
The fax unit cannot make automatic service calls in reaction to a Fax SC Code,
because the fax unit cannot make fax communications in fax SC Code conditions.
4.2.2 SC1201
When the FCU detects an unrecoverable error in the SR AM, which requires a
complete SRAM initialization, the fax unit displays this SC Code and stops.
There is no way to recover from this error condition without a complete SRAM
initialization (all the user and service programmed data will be erased ).
The possible causes are:
• SRAM backup battery defect, or TB3 on the FCU is at the “OFF” position
• SRAM on the FCU has a physical defect
• Flash memory card or data copy tool connection was loose
