Fitting the VHF converter to the AR3030 receiver
The following information is applicable to both the VHF AM (airband) and VHF NFM
(marine converter). Only one converter may be fitted at a time (they are not intended to be
interchangeable). Both are in fact capable of all mode reception.
The fitting is recommended to be carried out in an experienced specialist receiver
workshop.
STEP 1
Check that the following parts have been included in the packaging (cable colours may
vary):
1. Fitting sheet (this page).
2. VHF converter usually wrapped in foil.
3. 3 cable ties and four screws.
4. 5 leads as follows:
A = Grey mini coaxial screened lead with a mini coaxial plug on one end
and bare tinned wire contacts on the other (approx 38cm).
B = Long grey screened lead with 2 pin connector on either end
(approx 27cm).
C = Short grey screened lead with 2 pin connector on either end
(approx 19cm).
D = Coloured blue / white cable (2 blue & one white) with 3 pin
connector on either end (approx 28cm).
E = Coloured purple / white cable (three purple & one white) with 4 pin
connector on either end (approx 20cm).
STEP 2
It is assumed at this stage that the receiver has been tested and is working normally.
Carry out the following on a "soft surface" to prevent marking the set in any way... use the
correct size cross head screwdriver to avoid slipping and damaging screw heads.
Switch Off the receiver, disconnect the power supply and aerials, external speaker etc.
