Start/Shut down the machine
When start or shut down the machine, you
just need to press the function key for
three seconds (it will send out the "tick"
voice when starting the machine), which can
be operated like the cell-phone.
Switch over sound/mute
After starting the machine, it works in the
default mute detecting mode. If you press
the function key once to make the green
light blink, it works in the sound detecting
mode. If you press it again, it returns to
the mute mode.
Automatic Shut-Down
Over 4 minutes after it starts the machine,
if there is no signal been detected, it will
automatically shut down; if it detects out
signal within 4 minutes, it will
automatically re-calculate the delay time
used for automatic shut-down.
Cancellation of Automatic Shut-Down
If you press the function key 6 times in
succession within 3 seconds, indicator "auto
power off" is on, you can cancel the default
automatic shut-down function. If you repeat
this operation once more, it will return to
the default function.
Indication of Low-Voltage Battery
If the functional indicator becomes red from
green, it represents that the battery
voltage is low which needs to be replaced by
new battery.
Detect wireless candid-camera and
wireless eavesdrop signal
If it detects out wireless candid-camera and
wireless eavesdrop signal, it will send out
the "Bi Bi" voice (in sound mode), and the
functional indicator will distinguish, the 4
signals strength indicators will vary with
the signal strength. If the signal indicator
is in full bright, it represents that it has
been close to the suspicious signal source.
Shorten the antenna length and reduce the
detecting sensitivity to narrow the
detecting range, until it finally finds the
position of the signal source.
Detect signals cell-phone signal and
base station radiation of the cell-phone
If it detects both the signals cell-phone
signal and base station radiation of the
cell-phone, it will send out the Telephone
Ring (in sound mode), the 4 indicators of
signal strength will vary with the signal
strength, it is cell-phone signal when the
functional indicator is bright. If the
functional indicator distinguishes, it is a
base station signal when "B.S" the signal
indicator is bright.
Usage
skills
Pull out all antennas and hold the detector
while moving forward. If weak signal shows,
slow down the moving speed, change the
antenna direction slowly, adjust the antenna
length, and look for the signal to show
stronger direction, until the goal is found.
Signalling frequency and antenna
length relations
Detects the sensitivity and the antenna
length related, the inappropriate antenna
length can directly affect detects the
sensitivity. Wireless detects 5.8GHz to
photograph surreptitiously the signal, the
antenna pulls out 1 to 1.5; Wireless detects
2.4GHz to photograph surreptitiously the
signal, the antenna pulls out two; Detects
below the handset signal and the 1GHz other
signals, completely pulls out the antenna.
