● 005: NL equalizer
Use it to enable-disable the NL equalizer.
If errors occur often during communication because of the condition of the line, enable (ON)
the NL equalizer.
NOTE:
Any of the following error codes may be indicated at time of transmission because of
the line condition:
##100, ##101, ##102, ##104, ##201, ##281, ##282, ##283, ##750, ##755, ##765,
##774, ##779, ##784, ##789
Any of the following error codes may be indicated at time of transmission because of
the line condition:
##103, ##107, ##114, ##201, ##790, ##793
● 006: Telephone line monitor
Use it to s the telephone line monitor function:
DIAL: generate the monitor sound of the telephone line using the speaker from the start of
transmission to DIS.
SERVICEMAN [1]: generate the monitor sound of the telephone line using the speaker
from the start of communication to the end of it.
SERVICEMAN [2]: generate the monitor sound of the telephone line2 (Option).
OFF: do not generate the monitor sound of the telephone line using the speaker.

● 007: ATT transmission level
Use it to set the transmission level (ATT).
Raise the transmission level if errors occur frequently at time of communication because of
the condition of the line. (It means close to 8)
NOTE:
Any of the following error codes may be indicated at time of transmission because of
the line condition:
##100, ##101, ##102, ##104, ##201, ##280, ##281, ##282, ##283, ##284, ##750,

Any of the following error codes may be indicated at time of reception because of the
line condition:
##103, ##106, ##107, ##201, ##793
● 008: V.34 modulation speed upper limit
Use it to set an upper limit to the modulation speed (baud rate) for the V.34 primary
channel.
● 009: V.34 data speed upper limit
Use it to set an upper limit to the data transmission speed for the V.34 primary channel
between 2.4K and 33.6K bps in increments of 2400 bps. (0: 2.4K to 13:33.6K bps).
● 010: Frequency of the pseudo CI signal
You may select a frequency for the pseudo CI signal.
Some types of external telephones do not ring when the fax/tel switch-over function is ON.
To sound the ring, change the pseudo CI signal.
