detergent. Isopropyl alcohol or a glass cleaner can be used on
all Navigator surfaces.
Connection Cord/Plug Assembly Replace-
ment
If the RJ14 plug is damaged, it can be replaced. If it
is replaced, the wiring to the plug must be as shown below:
The connection cable can be replaced if damaged. Replace-
ment cables are available from Replacement Components
Division. Remove the Navigator from the LEN connection be-
fore proceeding.
1. Remove the 6 screws from the back of the case to gain
access to the internal plug for the device, and keep
them for installation later.
2. The back cover is connected to the touch pad by a ribbon
cable. The ribbon cable is not long enough to allow the
two halves to be completely separated. To be able to ac-
cess the plug connection, slightly offset the back cover.
Be careful not to damage the ribbon cable.
3. Unplug the damaged cable.
4. Plug in the new cable.
5. Insert the rubber grommet (included with new cable as-
sembly) into the cable entrance hole.
6. Realign the two halves of the Navigator. Be sure that the
grommet is properly seated in the cable entrance hole.
7. Reinstall the 6 screws previously removed.
NOTE: Failure to properly seal the Navigator with the screws
and grommet will compromise the watertight integrity of the
device.
