TS42DLX Deluxe Test Set
Users Guide
When the LO BATT LED begins flashing, the battery,
and thus the test set has anywhere from several hours
to several days of life remaining depending on how
often the speaker is used.
See “Replacing the Battery” on page 14 for instructions
on changing the battery.
If the test set stops working, remove the 9 V battery,
wait at least 40 seconds, then replace the battery. Use
the same battery if you know it is good or use a new
battery if you are not sure. This will reset the test set. If
it still doesn’t work, contact Fluke Networks Technical
Support.
Speaker and Speakerphone Microphone
See Figure 1.
The speaker and speakerphone microphone are
located on the keypad side of the test set. The speaker
draws more current than any other circuit in the test
set. The battery lasts longer if the speaker is used in
moderation.
Audio Controls
See Figure 2.
The three audio control keys are located on the inside
handle of the test set between the handset receiver
and the handset microphone. These controls allow the
operator to switch between the handset and speaker-
phone, to mute the active microphone, and to control
the volume of the received audio signal. Table 1
describes the audio control keys.

Warning
Never hold the speaker against your ear
when it is on, or when turning it on or off.
Sounds emitted by the speaker can be loud
enough to damage your hearing.
Keypad Controls and Indicators
See Figure 3.
The keypad has 19 keys that are recessed into the
receiver end of the housing. The recessed bezel
provides physical protection for the keypad and helps
prevent accidental key press. Table 2 describes the keys
on the keypad and other indicators on the test set.
