supply with the optional Power/Data Cable. The cable converts DC power to
a level usable by the receiver, and can also be used to output positioning data
for use by electronic navigation equipment that conforms to NMEA stan-
dards. (Do not use a non-Magellan cable, which may damage the receiver and
will void the warranty.)

THE ANTENNA

The receiver has an attached quadrifilar antenna, which rotates 360°. Using
the extension cable and suction cup provided with the optional Mounting Kit,
the antenna can also be removed from the receiver and temporarily mounted
to any convenient surface. (The antenna is removed by rotating it until its base
is parallel with the display, then pulling it away from the
receiver.) Since it can be used detached from the receiver, the
antenna can always be placed wherever it has the clearest view
of the sky.
In order to provide the best signal reception possible, the
antenna must be vertical. If attached to the receiver, rotate
the antenna from its storage position to
the upright position. If detached from the
receiver, the antenna should be mounted
as vertically as possible with the connect-
ing cable at the bottom.
GPS signals will pass through glass
and canvas (such as bimini tops).
You may experience some signal
loss in areas of heavy foliage. (Do
not stand under a tree in full leaf.)
Signals will not go through metal,
and you are unlikely to obtain
signals in a permanent structure.
Signals can be temporarily blocked by
trees, masts, and people. If you are
unable to obtain satellite signals when
out of doors, try moving slightly to get
a better view of the sky. If the receiver
is being operated in a covered location
(such as a navigation station), you may
want to use the optional External Antenna Kit. (Use only a Magellan antenna;
the use of a non-Magellan antenna may greatly degrade the performance of
the receiver.)
The best results will be obtained when the antenna has a clear, unobstructed
view of the sky.
