Last Number Redial
If a call is not successful and you wish to redial that
number, do the following: Put the TS30 Test Set into
Monitor mode, then put the unit back into Talk mode,
and press the REDIAL key. The last number dialed will
be automatically redialed. The number in the redial
memory is saved for about 8 minutes when the unit is
in Monitor mode. The last number redial function is
available in either the Pulse or Tone mode. The redial
memory has a 23-digit capacity.
Polarity Check
Connect the TS30 Test Set to a powered wire pair.
Move the TALK/MONITOR switch to TALK and press the
POLAR key. The green LED will light if the red test lead
is connected to a more negative voltage than the black
test lead. The red LED will light if the red test lead is
connected to a more positive voltage than the black
lead.
Transmitter Mute
When using the TS30 Test Set in a noisy environment,
such as near a street with a lot of automobile traffic,
the ambient noise will enter the TS30 Test Set’s
transmitter and a portion of the noise will be sent to
the receiver (side tone effect). This noise may be loud
enough in the receiver to make it difficult to hear the
person on the other end of the telephone line. Press
and hold the MUTE key to shut off the transmitter, thus
eliminating the ambient noise and making it easier to
hear the person at the other end of the telephone line.
Receiving Calls
To receive an incoming call, put the TALK/MONITOR
switch in the MONITOR position. Incoming call signals
on the telephone line will cause the TS30 to produce a
ringing sound. To answer the incoming call, move the
TALK/MONITOR switch to the TALK position.
