device, so there are no holes in the device for permanent
mounting. The module has a magnetic mount that is
strong enough to hold the device in place on any clean,
dry metal surface.

ComfortLink Main Base Board (MBB). The Navigator
module has a modular telephone style (RJ14) connector
and should be connected to a specific terminal block in
the control box as found in Table 1. This device is intend-
ed for use on the LEN (Local Equipment Network) com-
munications bus only. Do NOT connect the Navigator
module to the CCN (Carrier Comfort Network®) con-
nector, as it may damage the device.
To avoid the possibility of electrical shock, open and tag
all disconnects before installing this equipment. Be
aware that there may be more than one disconnect.

CLEANING, SERVICE, AND MAINTENANCE
TAB
Cleaning — The Navigator™ module can be cleaned with
a mild detergent. Isopropyl alcohol or a glass cleaner can be
used on all Navigator module 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 identical to the origi-
nal plug. Use Fig. 10 to record wire color. The wire sequence
should be the same for both ends of the cable as shown in
Fig. 10.

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.
6. Realign the two halves of the Navigator module. Be sure
that the grommet is properly seated in the cable entrance
hole.
7. Reinstall the 6 screws previously removed.
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.
NOTE: Failure to properly seal the Navigator module with the
screws and grommet will compromise the watertight integrity
of the device.
