Introduction
Upgrading the Course Computer
Disassembly
This booklet is intended to be used in conjunction with the standard
Raypilot 650 manual. The booklet covers:
•
Upgrading the standard Type 100/300 course computer to the
RayPilot 650 Professional version (see below)
•
Calibrating the Raypilot 650 Professional (see page 7)
•
Using the Raypilot 650 Professional in Workboat mode
(see page 15)
1. Remove the terminal cover (1).
2. Unscrew and remove the four M3 screws (12) on the lower case
(11). Remove the lower case.
3. To remove the PCB (8), unscrew and remove the five M2 screws
(9). Unscrew by two or three turns the location comb screws (5).
(Note that recent computers use machine screws and require a
2.5 mm hexagon key). Access to these screws is gained through
two holes in the PCB, one of which is shown in the following
figure, behind and to the left (as viewed) of the line of FETs (13).
Do not remove the screws at this stage. Lift the PCB out of the
upper case (2).
4. Remove the location comb (4) by removing the two screws (5).
5. If the insulation strip (3) is damaged, out of position or a new
location comb is to be fitted (see assembly instruction 4),
carefully peel off the old strip and clean any remaining adhesive
and heat transfer compound off the case.
6. The PCB insulating strip (10) fits over the legs of the connectors
and can be removed if necessary.
7. Remove the EPROM (14) from its socket by gently prising it out
with a screwdriver.
