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.
