cable lengths.

PLANNING: GS25/Point-1, Mounting location

GS25/Point-1

The antenna contains a magnetic heading sensor and should not be
mounted within 1 meter (3.3 ft) of any potential magnetic source.

RC42N

Select a location that provides a solid mounting place free from
vibration, min. 1 meter (3.3 ft) away from any potential magnetic
source, and as close to the vessel’s centre of roll and pitch as
possible, i.e. close to the water line.

Potential sources for magnetic/electromagnetic interference include:

• Electrical Motors/Magnets/Moving Metal items

• Outboard Engines

• High current electrical sources such as main power cables,

batteries, distribution panels etc.

Compatibility information

The hydraulic kit comes with 1/4 NPT 9/16 UNF ttings for nylon
tube or exible hoses which make them ideally suited for the
following steering systems:

• Teleex SeaStar HC5345, HC5347, HC5348, HC5358.

• Teleex BayStar HC4600, HC4645, HC4647, HC4648, HC4658.

• Hynautic K6 Steering Rams.

• Also rams from Vetus, Uex, Lecomble and Schmitt can be used.

MOUNTING: Bleeding

Turn wheel gently in both directions, and rell oil.
Repeat turning and relling oil until the oil level is stable and no

air bubbles left in the transparent tube, and the outboard engine
responds rmly.

If air bubbles still remain in the system, follow the bleeding procedure
described for the outboard cylinder.
