To Turn the VHF Transmitter On
Place a magnet on the dimple for one to two seconds.
NOTE: The dimple is a small concave depression and is located on the
front surface (left) or underside of the battery holder.
Result: The VHF transmitter will broadcast a squeal, and then
broadcast five fast pulses followed by regular pulses (nominal pulse
rate).
NOTE: Signal drift can occur over time and because of seasonal
temperature changes. You may have to fine-tune the frequency either
side of the expected frequency.
2.2.1.
What can I do if I can’t pick up a signal?
If the VHF receiver could not pick up the VHF signal:
Check the VHF receiver is programmed to the correct frequency
Ensure the VHF transmitter, VHF receiver and antenna all operate in
the same frequency band
Adjust the VHF receiver’s sensitivity (gain)
Fine tune the VHF receiver’s frequency 1 to 3 kHz either side of the
listed frequency
Check the VHF receiver’s batteries and replace if necessary
For more information, see ‘Tips & Troubleshooting’, later in this guide. If the
receiver’s batteries are charged and you have tried another VHF receiver
without success, please contact Lotek for assistance.
