Basic Operation
Adjusting the Squelch
The squelch silences the DJ-X3 except for signals above a certain level.
Squelch eliminates noise when the DJ-X3 receives less than a certain level.
"To unmute the squelch" means that the DJ-X3 receives a signal higher than
the squelch setting and reproduces the sound.
Conversely, "to close the squelch" means that the DJ-X3 does not generate
audio because of insufficient signal level.
■
Adjusting the Squelch Level
You can specify the signal level at which the DJ-X3 unmutes by adjusting the
squelch level.
1
Press the [VOL/SQL (SET)] key (dial) twice.

correctly.
· When the battery voltage is low, this function does not work normally. Be
sure to recharge the battery pack completely, load new AA batteries, or
supply sufficient voltage from the DC power supply.
· Since this function detects a bug’s signal by the presence or absence of a
howling noise, a loud sound may be emitted during detection; however, it
is not a malfunction.
· Detection area is approximately 15 square meters (18 square yards)
depending on the type of listening microphone.
How do you stop detecting?
Turn the power OFF, then turn the power ON while holding the [MONI(ST/SK)]
key down.
