Fitting the RU2700 recording option to the AR2700 receiver
The fitting is recommended to be carried out in an experienced specialist receiver
workshop.
1. Remove the rear battery compartment cover
from the AR2700 receiver.
2. Remove the batteries (if fitted).
3. Remove the two black self tapping screws
from the lower section of the battery
compartment. Store in a safe place.
4. Remove the two screws from the both the
left & right side panels (only the rear case
half screws need be removed).
5. Ease the two case halves apart, be careful not
to strain the speaker connecting wires.
Unplug the speaker connecting plug from the
PCB.
The front case half comprises of the LCD, keypad,
side keys & speaker.
The rear case half comprises of the top panel, I.F. PCB,
R.F. PCB and battery compartment.
6. The I.F. PCB needs to be removed, be careful not to
damage the battery connecting leads as they are
soldered in place.
Pull off the three knobs for the VOL, SQL & DIAL and
remove the three locking nuts using a pair of long nosed
pliers etc.
7. Remove the two (long) self tapping screws which are
holding the bottom edge of the I.F. PCB.
8. Lift the I.F. PCB clear of the cabinet (start by lifting the bottom of the I.F. PCB so that
the controls will pass backward through the top panel holes). The DC leads remain
attached to the I.F. PCB so be careful to restrict movement to a minimum.
9. Turn the I.F. PCB up-side-down and refer to the diagram overleaf...
