4.1 Modem Test
The test starts from silence (the machine only goes off-hook), then by pressing the # key the signal changes to
9,600bps - 7,200bps - 4,800bps - 2,400bps - 300bps - 600Hz - 1100Hz - 2100Hz. (Press the * key to go back-
wards through the sequence.)
After you have finished the test, press EXIT to go back to step 3.
4.2 DTMF Test
Press a key on the dialpad (0 - 9, * and #) to test the DTMF signal.
After you have finished the test, press EXIT to go back to step 3.
Note that the machine will emit a DTMF signal with the country specific length, even if the slide switch on the

If you wish to get a continuous DTMF tone, set the slide switch at ‘‘Tone’’, switch off the power, then press the
required key on the dialpad.
