· Earphone jack and speaker
Optional:
· Additional 2 MHz band (nearby) covered
This receiver is micro-processor controlled.
It covers any 2 MHz band between 1 8 and 175
MHz. An adjacent 2 MHz band can be included as
an option.
The receiver includes 40 programmable channels,
and it also includes a scanner function for the
programmed channels.
The PERDIX VHF receiver has one external antenna
socket.
The frequency is set by a knob to the closest 1 kHz.
Also fine trimming of the frequency (tone) and the
gain is controlled by knobs. The frequency set is
shown on a LCD.
The strength of the signal received is indicated on
a LED array and also by a loudspeaker or earphone.
The receiver is powered by 2 alkaline or NiMH
(rechargeable) batteries.
The robust PERDIX VHF receiver Tracking Receiver is designed and manufactured for field use, to
withstand adverse weather conditions.

Operating instructions
To turn the receiver ON or OFF press and hold the push-button for 2 sec.
It will start either in frequency mode or in channel mode. Frequency mode will display a frequency and
channel mode will display a channel number (two digit number from 01 to 40) and the corresponding
frequency. The receiver will start in the same mode that it was in when it was previously turned off.
In case of low voltage “LOW BAT” is seen on display. If the FREQ knob on the front is pushed the display is
illuminated for 6 seconds or as long as the knob is moved. The knob must be pressed down and released
to be able to change the frequency.
To toggle between modes, press and hold the FREQ knob until the mode changes. This can be seen on the
LCD.
Frequency Mode
Changing the frequency:
To change the frequency from the one displayed begin by pressing, then releasing the
FREQ knob
. The
rightmost digit will be underlined. Change that digit by rotating the knob. To move to the next digit to the
left, press and release the knob again. Continue changing the frequency using the method described.
Channel Mode
Setting the channel frequency:
1. Utilise the frequency mode to tune the receiver to the desired frequency according to the method
described above.
2. Press and hold the FREQ knob until the text “Channel xx” is displayed. XX represents a two-digit number
ranging from 01 to 40.
. Turn the FREQ knob until the desired channel is displayed. If too much time elapses between pushing
the dial and rotating the dial you must begin again. The indication that too much time elapsed is that the
line under the channel number will disappear.
4. To set the new frequency of the channels quickly press and release the On/Off button. This must be
done before the background light goes off. Note that the receiver will turn off if the button is
press and held.

Including and excluding channels in the scan:
1. In channel mode, select the channel to include in the scan.
2. Change to frequency mode.
. Press and hold the FREQ knob until the channel number is displayed and a star “*” appears after the
channel number. The star identifies the channel as selected and it will be included in the scan.
To exclude channels, repeat this process but press and hold the FREQ knob until the star disappears.
Start the scan function:
1. Make sure the receiver is in frequency mode.
2. Press and hold the On/Off button and immediately press the FREQ knob while still holding down the
On/Off button. The display will show “Please Wait”. Release the On/Off button and the FREQ knob.
After a few seconds the display will show “Scan Chxx 1s”. 1 s is the time (in seconds) for which a channel
will be scanned before moving on to the next channel included in the scan. Change this value by turning
the FREQ knob slowly. Values from 1 to 9 can be used.
Interrupt the scanning function by pressing the FREQ knob.
Point (preferably horizontally) with the front of the external directional antenna at the transmitter.
To set the transmitter frequency press the FREQ knob (and release it) to change the 1 kHz digit
(underlined) by turning the FREQ knob. Push the FREQ knob again to change the 10kHz digit (underlined)
and set the frequency by turning the knob. In the same way the 100 kHz and the MHz can be changed.
When the light goes out after 6 seconds the FREQ knob can be turned without changing the frequency.
Turn the GAIN knob until the diodes and the speaker indicates that a signal is received.
Turn the TONE knob to adjust the fine frequency for maximum signal strength. If necessary, change the
gain setting to get the PEAK DETEC- TOR (topmost diode) to be visible only when the receiver is pointing at
the transmitter.
When “LOW BAT” is seen on the display open the battery compartment on the back of the receiver and
replace the two batteries. The batteries should be taken out during prolonged storage.

Tracking:
Turn around to find the proper direction as indicated by the diodes and heard from the loudspeaker or the
earphone (plugged in at the bottom, disconnects the loudspeaker). The strongest signal should be
received when the top points at the transmitter. A weaker signal is normally heard in the opposite
direction.
As a rule, one should move around a little during the tracking process to reduce the reflecting and
dampening influence from the nearby terrain or objects. Try to find elevated and free areas for taking
bearings, if possible. Do not stand near reflecting objects like a car or a big rock.
Theory and practice donʼt always coincide, but, as a rule the vertical position of the receiver may give a
stronger signal in a forested terrain. However, the direction of the signal received may be very false.
Tracking from short distance from the transmitter is normally a problem for the inexperienced person.
However, the PERDIX VHF receiver has good dynamic properties, which makes it easy to use even close to a
strong transmitter.
Care:
As mentioned above, do not keep the batteries in the receiver during prolonged periods of non-use.
If the receiver has been used in heavy rain and there is moisture inside, open the battery compartment,
take out the batteries and let the receiver remain open over night in a dry and warm place. This normally
will restore any performance of the receiver that may be affected by penetrating water.
