Detailed procedure

Interruption cannot be made during operation.

Note: Executable only when the FAX is installed.

By setting the message No., the signal is sent to the line and the
speaker of the body. (The signal is continuously sent until the interrup-
tion command is provided by pressing the [BACK] key.)

The signal send level can be selected from 0dB or the soft SW set
value. However, the level setup is not required for 01, 31 - 35, the
selection may does not appear. After completion of the mode, the sig-
nal send level is returned to the soft SW set value before execution of
the mode.

AR-FX4 SIMULATION - 5

Note: Executable only when the FAX is installed.

The confidential ID table (confidential BOX numbers, confidential BOX
names, and confidential password) is printed. 

The confidential data of My company mode is printed separately.

Note: Executable only when the FAX is installed.

Used to input all image data (including confidential reception data,
remote send image, not-sent image) stored in image memory of the
FAX section.

The output image is remained even after outputting.

Note: Executable only when the FAX is installed.

Used to clear all image data (including confidential reception data)
stored in image memory of the FAX section.

The management table is also cleared (initialized) at the same time.

Note: Executable only when the FAX is installed.

By setting the signal number, the specified signal is delivered to the
line at the speed of 300bps. (The signal is continuously sent until the
interruption command is provided by pressing the [BACK] key.)

The signal send level can be selected from 0dB or the soft SW set
value.

The signal send level is returned to the soft SW set value before exe-
cution of the mode after completion of the mode.

Note: Executable only when the FAX is installed.

The send test of dial pulse and DTMF signal is performed and the
make time adjustment of dial pulse and the DTMF signal send level
adjustment are performed if necessary.

• Used to set the make time. By performing the test, the registered

dial pulse of max. 100 digits can be sent from the line.

• When "*" and "#" are included in the registered dial number, they are

disregarded and the number is not processed as a dial.

• The make time set in the dial test is written into the corresponding

soft SW.

• Default: 1 2 3 4 5 6 7 8 9 0

• Set the signal send level to 0dB or the soft SW set value.

Used to set the high level group and the  low level group of DTMF
signal send level. By executing the test, DTMF signal is sent from
the line to a recorded dial number of max. 100 digits.

• The high group/low group value of the DTMF signal send level set in

the dial test is written into the corresponding soft SW.

• Default: 1 2 3 4 5 6 7 8 9 * 0 #

In the PB dial select menu, press [

Pressing the [CLEAR] key during the operation clears the input
value and returns to the value input menu.

• Max. 100 digits can be assigned to each dial (0 - 9, *, #). While the

default value is displayed at first, a desired value can be entered and
the entered value is stored on the FAX side until the menu is can-
celed.

• After completion of the mode, the signal send level is returned to the

soft SW set value before execution of the mode.

Note: Executable only when the FAX is installed.
