9-10 Bug Detector Function
This function automatically scans frequencies possibly used by bugging devices
(wireless microphones) to
fi
nd such devices. When the receiver determines the
presence of a bugging device, it provides noti
fi
cation via the display and an alarm.
The DJ-X11 provides two modes for the function: Silent and Sound.
The default setting is a combination of both Silent and Sound modes. Refer to
"Mode coupling setting of the Bug Detector function" (P. 71).
It is also possible to search for bugging devices by linking the user-programmed
memory banks to the bank for Bug Detector channels.
MEMO
• In the Silent mode, you can set the search sensitivity of the Bug Detector
function. Refer to “Sensitivity setting of the Bug Detector function” (P. 72).
• The Bug Detector function searches the memory channels in the bank
linked with the bank for Bug Detector channels. Refer to “Bank Link
Setting Function” (P. 54).
CAUTION
• When Voice Guidance is active, an announcement of “Detected” might
be made even when non-bugging signals are received due to a mal-
function caused by use environments or radio signal conditions. Note
that this is an accessory function and should be used as a guide only.
• This function is designed based on a simple method and does not
guarantee security and safety. Alinco does not guarantee against the
failure of bugging device detection.
• Alinco does not provide any services such as discovering bugging de-
vices or dealing with discovered devices.
• Alinco’s Customer Service will not answer any general inquiries con-
cerning bugging attempts other than the operation and operating pro-
cedure for this function.
9-10-1 Operating procedure in Silent mode
This mode provides an accurate search by producing the sound of received
signals from the speaker and making a judgment based on the occurrence of
a "howling" phenomenon which occurs if the signal is emitted from a bugging
device. When you hear this ambient sound from the speaker, a bugging
device may possibly be installed. (Be careful, as the sound may be loud.)
If you want to use the Silent mode alone, set the "Bug coupling" option for
the mode coupling setting of the Bug Detector function to "OFF".
