Operation
Speaker Timeout
The speaker draws more current from the battery than
any other circuit on the test set. The battery will be
drained quickly if the speaker is left on continuously. To
extend battery life, the test set has a timeout function
that automatically turns off the speaker when the test
set is on-hook. A timer is started whenever the test set
is put on-hook. As long as the test set is off-hook the
timer will not start.
If the test set is used as a handset in Monitor mode and
if the test set’s receiver has been set to high volume,
the battery will be asked to deliver enough current to
drain the battery sooner than desired. So the same
timeout that is applied to the speaker is applied to the
high volume state in Monitor mode. If the test set is in
Monitor mode with the receiver’s volume set to high
volume, after the timeout the test set will revert to low
volume. When the test set is in Monitor mode with the
speaker off and with the receiver volume set to low, it
draws very little current from the battery.
The speaker timeout duration is programmable while
on-hook and 240 minutes (4 hours) while off-hook. The
off-hook timeout cannot be changed. Remember, the
longer the selected timeout duration the shorter the
battery life.
To change the speaker timeout duration:
1
Set the Talk/Monitor switch to M.
2
Press the STORE/PROG key.
3
Press the SPKR key.
4
Press a number key to select a duration. Invalid
entries are ignored. The test set gives a
confirmation tone when the entry is accepted.
