Loudspeaker; Maintenance - Test-Um Lil' Buttie Ranger User Manual

Lil' Buttie RANGER
The test set decodes all 16 possible DTMF tones. The
DTMF display remains on the screen for about two
minutes unless the TALK/BELL/MON switch is changed
or the FCN CL key combination is pressed to CLEAR
the display.

4.9.9 Loudspeaker

The Ranger has a loudspeaker that can be used in
MONITOR and TALK modes to allow the test set to
be used like a speaker phone so that the signal on the
line can be heard without being close to the test set.
The loudspeaker is controlled by the Speaker and Mute
buttons as described in Sections 4.3 and 4.4. The Ranger
provides a feature called Insta-Talk
like 2-way conversations in TALK mode. The loudspeaker
times out in about 15 minutes and the test set goes back
to normal earpiece/head set mode automatically. The
loudspeaker is automatically set to OFF every time the
test set goes from TALK to BELL modes or MONITOR
to BELL modes unless the time between TALK and
MONITOR modes is less than 3 seconds.
Note: The loudspeaker draws a large amount of power
and can discharge the battery quickly if used at high
volume on a line with a lot of signal.

5. Maintenance

You can clean the Ranger with a damp cloth. If the test
set is very dirty, you may apply a small amount of liquid
soap to the cloth to assist in cleaning. Do not use sol-
vents, scouring powders, or other abrasive cleaners that
might scratch the test set and/or cause malfunctions.
You should periodically check the Ranger's cable set
for shorts, continuity, or obvious signs of wear, such as
fraying or loose/damaged test clips.
