2.2 Receiver control and indication modes
The receiver can work with acoustics or electromagnetism sensors. This set is intended for
operation with the electromagnetic EMD-247 sensor. The type of the sensor is determined
automatically. For an acoustic sensor there is only a broadband reception mode, as evidenced by
the constantly blinking right LED box marked WB. For an electromagnet sensor there are several
reception frequencies.
The light emitting diode scale executes indication of several functions:
а) this is an indication of a power battery condition,
b) a frequency of the received signal is switched in a circle,
c) a sensitivity is more-less,
d) a volume is more-less.
To understand where you are, one needs to know the following: at startup the scale is checked,
i.e. consistently included 4 cycles of running lights, then a slight pause, then highlighted the level
of battery power state for 5 seconds, then the signal strength is displayed.
(when the acoustic «AD-227» sensor is connected to the receiver, the filter frequency is not
displayed);
5. It is turning into the operating mode, the LED display is indicated by the input signal level at
a selected frequency:
and a synthesized audio signal is given on headphones.
Turning off the receiver is performing by briefly pressing the button «Power On / Off».
Low input level
High input level
-
Activation/deactivation of the receiver.
The receiver turns on when one-time
pressing the
«Activation/deactivation of the power»
button. When you turn on, the device
consistently:
1. Enable animation plays («running lights» on the LED display);
2. About 4 seconds indicates battery charge (if all the LEDs are lit, than the charge is maximum,
if the first led light blinks, the device is turned off or the batteries are low):
3. Sound plays when the instrument turns on;
4. If the «EMD-247» sensor is attached for around 2 seconds, one light emitting diode of the light
emitting indicator diodes displays the operating filter frequency (for example, 1024 Hz – «1k»),
