Hook Flash Duration
When the test set is off-hook, pressing the

key causes a timed interruption of the loop
current to occur. Some PBX setups or telephone office
switches may use this signal to put a call on hold or to
activate some special function. One flash is generated
for each press of the key.

Make Receive-Only Loud Speaker the Default
On a TS52PRO fresh from the factory, if you take the
unit off-hook and press the
SPKR
key, the Speaker-
phone will turn on. The Speakerphone allows you to
have a two-way, hands-free conversation like with any
desk top speakerphone. If now you press the
MUTE
key, the Receive-Only Loud Speaker will be enabled
temporarily. When the Receive-Only Loud Speaker is
enabled, the speakerphone microphone is shut off and
the test set can only receive audio signals – it cannot
transmit any audio signals. Receive-only is preferred
when your main concern is to listen to the line and you
do not want ambient noise such as caused by a passing
car to switch the Speakerphone into transmit mode.
Quite a few users have requested that the Receive-Only
Loud Speaker be made available on a more permanent
basis. In other words, when they press the
SPKR
key on
an off-hook unit, they want the Receive-Only Loud
Speaker to be activated rather than the Speakerphone.
The Receive-Only Loud Speaker suits their working
style and they do not want to press the
MUTE
key every
time they want to activate the Receive-Only Loud
Speaker.
If you frequently have two way conversations, then you
probably want the Speakerphone to be the default
Loud Speaker mode. If you mostly listen when the loud
speaker is on, then you may want the Receive-Only
Loud Speaker to be the default Loud Speaker mode.
You can configure the test set to make the Receive-
Only Loud Speaker the default Loud Speaker mode
instead of the Speakerphone by performing the
following programming procedure.
To enable Receive–Only Loud Speaker as the default
off-hook speaker mode (assuming the unit is presently
set for Speakerphone):
1
Set the Talk/Monitor switch to
M
.
2
Press the
STORE/PROG
key.
3
Press the
MUTE
key. The test set gives a
confirmation tone.
If you want to restore the Speakerphone as the default
off-hook speaker mode, then repeat the steps above.
