Users Guide
Display and Keypad
See Figure 3. The TS52PRO has a 10 digit LCD and a
keypad that is recessed into the housing.
The recessed bezel protects the keypad and helps
prevent accidental key presses. Table 2 describes the
keys and display icons.

VOL
(Volume)
Pressing the
VOL
key switches the active receiver’s sound level between normal and high volume.
This occurs in Monitor mode and Talk mode. The state of the
VOL
key is preserved when the active
receiver is changed. For example, with the handset receiver volume set to high, if you switch to the
speaker, it will also be set to high volume. The
VOL
key affects only the volume of received signals. It
does not affect the volume of transmitted signals. Successively pressing the
VOL
key toggles the test
set between low and high volume. The volume icon on the display indicates low and high volume
mode. High volume is indicated by the volume icon (sound bars) and the absence of the icon
indicates low volume.
To preserve battery life, the high volume mode will time out. See the section "Speaker/LCD/Test Set
Timeout" on page 16 for information on setting the timeout.
SPKR
(Speaker)
The
SPKR
key turns the test set’s speaker on and off. It functions in both Talk and Monitor modes.
In Monitor mode, if the test set is being used as a handset, pressing the
SPKR
key turns on the
speaker. This lets you monitor a line while working at a distance from the test set. When the speaker
is on, the speaker icon is shown on the display.
If the test set is off-hook and is being used as a handset, pressing the
SPKR
key turns on the
Speakerphone. The handset microphone and receiver are shut off and the speakerphone
microphone and speaker are enabled. This mode is intended for two-way, hands-free conversation.
You may also program the test set to operate exclusively in Receive-Only Loud Speaker mode (see
"Make Receive-Only Loud Speaker the Default" on page 15). For a test set configured this way, if the
test set is off-hook and is being used as a handset, pressing the
SPKR
key will turn on the Receive-
Only Loud Speaker rather than the Speakerphone. Receive-Only Loud Speaker mode is intended for
listening to the line, hands free.
