External Power
The Meridian XL can also be operated from an external DC power source.
This requires the Power/Data Cable that is included with the optional
mounting kit. (Even when operating from external power, the receiver
must have batteries; the batteries will be used to maintain memory when
the receiver is off.)
The cable converts DC power to a level usable by the receiver. It also can
be used to output positioning data to electronic navigation equipment
that conforms to NMEA standards, and to import broadcast differential
corrections from a differential beacon receiver.
The use of a non-Magellan cable or an altered Magellan cable
may damage the receiver and will void the warranty.
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 detached from the receiver and temporarily
mounted to any convenient surface. (The antenna is detached 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 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 connecting cable at
the bottom.
GPS signals will pass through glass and canvas (such as bimini tops)
however, you may experience some signal loss in areas of heavy foliage.
(Do not stand under a tree in full leaf when attempting to take a fix.)
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.)
