Basic Operation
1Select the dial signaling required (touch tone or pulse)
with the TONE/PULSE switch.
2Set the TALK/MONITOR switch to Mand 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.
3Set the TALK/MONITOR switch to T, and verify that
dial tone is received.
4Dial 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.

TS22 Amplified Speaker Mode
1Connect the test set to the line, put the test set in
TALK (T) mode, and receive dial tone.
2Press the SPEAKER button once for Amplified Speaker
mode at low volume. The transmitter and receiver
automatically turn off when the speaker is on to
prevent acoustic feedback.
3Press the SPEAKER button a second and third time for
medium and high volumes.
4Press the SPEAKER button a fourth time to turn the
speaker off and return to TALK mode.
Note: When the speaker is on, the polarity LEDs are off.
They turn back on when the speaker timer elapses or is

TS22A Speakerphone Mode
1Connect the test set to the line, put the test set in
TALK (T) mode, and receive dial tone.
2Press the SPEAKER button once for Speakerphone
mode at low volume.
3Press the SPEAKER button a second and third time for
medium and high volumes.
4Press the SPEAKER button a fourth time to turn the
speakerphone off and return to TALK mode.
Notes: (1) Pressing the MUTE button while in
Speakerphone mode mutes the transmit microphone for
privacy. (2) When using Speakerphone mode in noisy
environments, it may be helpful to temporarily lock the
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.
