5.5.2.3.2 Details of Bit 0

0008-1887

It is possible to select whether or not to detect carrieir disconnection between the DCS signal and the TCF signal during reception.

If the receiving machine returns an FTT signal while the other machine (PC-FAX) is transmitting a TCF siganl and a reception error occurs, set this bit to "1".

If thw error still occurs, set bit 1 of #SSSW SW18 to "1".

5.5.2.3.3 Details of Bit 1

0008-1889

It is possible to select the detection time for caarrier disconnection between the DCS signal and TCF signal during reception.

This bit is available for use when #SSSW SW18 Bit0 is set to "1".

If the symptom is not resolved by setting SW18 Bit 0 to "1," set this bit to "1."

5.5.3 Data Initialization Mode (CLEAR)

5.5.3.1 # CLEAR

0008-3182

Registration/settings of user data and service data are initialized with CLEAR ALL, and go back to factory defaults.

Reference

Since the TYPE setting of #CLEAR item goes back to STANDARD when #CLEAR ALL is executed, there is a need to change the TYPE setting to

conform to the communications standards of a specific country/region.

5.5.4 Test Mode (TEST)

5.5.4.1 Overview

5.5.4.1.1 Test Mode Overview

0008-1953

The following test modes are available from the menu on the display.

D-RAM tests

Writes data to DRAM image storage areas and reads that data to check operations.

Print test

Printing a test pattern in the printing area.

Modem, NCU tests

The frequency test, G3 signal transmission test, and V.34 G3 signal transmission test.

FACULTY test

Testing the sensors and functions of the operation panel.

5.5.4.2 DRAM Test

5.5.4.2.1 D-RAM Test

0008-1979

D-RAM test menu is selected by pressing the numeric key 1 from the test mode menu. D-RAM Test 1 writes data to the entire D-RAM region and reads it out to

check that operations are correct. D-RAM Test 2 just reads data at high speed.
