APPENDIX > INSTALLING THE FERRITE BEAD CLAMP
Installing the Ferrite Bead Clamp
In order to filter Radio Frequency Interference (RFI) radiation
that could possibly interfere with items such as televisions, radios,
or other marine electronics operating in close proximity to the
GPSMAP 182/182C with the remote antenna, a ferrite bead filter
clamp and neoprene foam strip are included for attachment to the
unit’s antenna cable. The clamp attaches to the antenna cable near
the point it connects to the back of the GPSMAP 182/182C. The
foam strip has adhesive on one side and is used to keep the clamp
stationary on the cable.
To install the ferrite bead clamp:
1. Choose a location where there is no more than two inches
(5 cm) from the back of the GPSMAP 182/182C.
2. Remove the backing from the adhesive foam strip. Place
the strip at an angle to the cable with adhesive facing
towards the cable. Snugly spiral wrap the foam strip around
the antenna cable. (Figure 1)
3. Open the filter clamp by slightly pulling on the latch and
opening the filter halves.
4. Position the clamp (Figure 2) and squeeze it shut around
the cable until the latch is securely fastened. If the clamp is
difficult to close, you can want to remove some of the foam
strip.
The clamp should not need to be replaced under normal use.
Contact your Garmin dealer or Garmin Product Support if you have
any questions or require a replacement filter clamp.
