Cause
Countermeasure

can properly receive the image signal.
(2) Have the other party lower the other
machine's transmission start speed.
(3) Adjust the NL equalizer in #2 MENU para-
meter 005, so the other party's machine
can properly receive the image signal.

termeasures.

Countermeasure
(1) Raise the modem output level in #2 MENU
parameter 007, so the other party's machine
can properly receive the image signal.
(2) Lower the Tx start speed in user mode
system settings.
(3) Add an echo protect tone to the V29
modem signal in #1 SSSW-SW03 Bit 1.
(4) Have the other party ease the RTN trans-
mission conditions for their machine so
that RTN will not be transmitted by the
other party's machine.
(5) Adjust the NL equalizer in #2 MENU para-
meter 005, so the other party's machine
can properly receive the image signal.
(1) Refer to #1 SSSW-SW03 for echo coun-
termeasures
(2) When registering in autodial, add a long
pause after the telephone number so
there will be no response to the other
party's first DIS.
(3) When calling manually, press the start
button after you have heard the other
party's first DIS.
(4) Have the other party lower the output
level so the other party's machine will not
receive echoes.
