HI Z/RING/TALK SWITCH
Figure 2. Handgrip Controls
(a) HI Z/RING/TALK Switch. This three-position
slide switch is located on the inside of the handgrip just
above the transmitter. The switch is labeled as HI Z for
high impedance monitoring, RING for ringer and low
impedance monitoring, and TALK for talk.
In the HI Z position, the TS19 is on-hook with a
high impedance coupling to the telephone line.
This allows for telephone line monitoring without
disrupting conversations, data or signaling.
In the RING position, the TS19 is on-hook with an
electronic ringer connected to the telephone line.
The TS19 is low impedance coupled to the line for
monitoring of optional line identification tones.
Also, the TS19 provided enhanced receive levels.
In the TALK position, the TS19 is off-hook and
may be used for dialing and talking. In this mode,
the TS19 performs as an ordinary telephone.
(b) PULSE/TONE Switch. This two-position slide
switch labeled PULSE/TONE, is located on the inside
of the handgrip just below the receiver. The switch
selects the signaling output. TONE for DTMF of
PULSE for dial pulse.
