Harris TS22 Series User Manual

6 TS22 Series Test Sets
TONE/PULSE
Switch
This toggle switch has two functions: as a TONE/PULSE switch and as a ringer
on/off switch.
Polarity Light
Emitting Diodes
(LEDs)
Located at the top of the keypad, these round LEDs illuminate automatically to
indicate line polarity when off hook. The green LED will light if the red test lead
is connected to the ring (negative) side of the line and the black test lead is
connected to the tip (positive) side of the line. The red LED will light if the test
leads are reversed; that is, with the red test lead connected to the tip (positive)
side and with the black test lead connected to the ring (negative) side. The
LEDs will flash momentarily during pulse or tone dialing, and are turned off
while in Speakerphone mode or Amplified Speaker mode.
Note: The TS22 Series Test Sets
are not polarity sensitive, and will
function in either polarity.
Switchable On/Off
Ringer
The TS22, TS22DS, and TS22A each use an electronic ringer. For
convenience, the ringer can be switched on and off by the dual function TONE/
PULSE switch. In talk mode, this dual function switch selects the TONE or
PULSE) dialing mode. In monitor mode, it selects ringer on and ringer off (see
Figure 5).
Switchable
Electronic Ringer
With the amplified monitor speaker ON, the audible warble is enabled. The
amplified speaker can be used to hear incoming ringing, as the amplified
speaker amplifies any audio receive signal in either the TALK or MONITOR
mode.

Amplified Speaker (TS22 and TS22DS)
The TS22 and TS22DS are equipped with an Amplified Speaker that
amplifies the receive signal in either the TALK or MONITOR mode. This
allows you to listen to the test set without holding it to your ear. The speaker
control button is located on the inside of the handgrip, just below the
receiver. There are three volume settings and an OFF position.
When the speaker is off, pressing the button once turns the speaker to low
volume. Pressing the button again raises the volume to medium, pressing
the button a third time turns the speaker OFF.
