R34 F code When performing F-code
recepti (confidential/relay)
on communication, the
(Ph.B) password information as
well as the box number
(SUB) are received with
PWD but not SID.
How to correct
1. Set the coding method to MH/MR/MMR.
2. Change the lowest reception sensitivity to -43 dBm.
Change the signal transmission level to -15 dBm.
3. Set the reception beginning speed to V.29-9600bps.
4. Possibility of line defect (example: packet loss, echo,
distortion)
5. It cannot be dissolved by settings, so acquire a log.
• Protocol trace list for errors (including remote station)
• Line information for both fax machine and remote
station
• Machine management list (CSV save), activity report

1. Increase the timer between frames by +10 seconds.
* If no effect is obtained, return the setting.
2. After the V.17 reception error occurred, configure
settings to decrease the constant time capacity on V.29/
V.27ter.
3. Decrease the reception beginning speed to V.29/V.27ter. [Modem/NCU] -> [V17 Send Max
4. Possibility of line defect (example: packet loss, echo,
distortion)
How to correct
Turn OFF the DTS function.
Request the machine on sending end to set the password
information to SID but not PWD.
NOTE) PWD is used for SEP polling.
