Basic Operation
1
Select the dial signaling required (touch tone or pulse)
with the TONE/PULSE switch.
2
Set the TALK/MONITOR switch to M and connect the
test set to the line. Listen to verify the line is idle. The
test set's high impedance prevents disruption of data
traffic when connected to a line in monitor mode.
3
Set the TALK/MONITOR switch to T, and verify that
dial tone is received.
4
Dial the number to be called. To terminate the call
during or after dialing, set the TALK/MONITOR switch
to M.
Last Number Redialed
In Tone or Pulse mode, the last number dialed can be
redialed by pressing the LNR key after going on-hook
(MONITOR) and then back off-hook (TALK).
Note: When dialing out through a PBX, you may use the
PSE key to insert a pause before initially dialing the
number.

MUTE button while listening; then unlock it to talk.
To prolong battery life, the TS22A shuts off the
speakerphone after about 5 minutes when there has been
no signal greater than -30 dBm. Speakerphone mode
must be reactivated every 5 minutes if no signal greater
than -30 dBm is detected.
