• GNSS and AIS performance may suffer if large angles of the horizon are blocked, such as if the Petrel is next to a wall. • Do not use conductive material at the top of the Petrel around the glass lens; this will cause the water sensor to fail.
GPS lock and will not transmit or receive AIS messages. GPS Search Mode In GPS Search Mode, the Petrel unit will attempt to acquire a GPS lock. While in this mode, the unit’s Bluetooth and AIS functionality are inactive.
A Petrel’s AIS transmissions contain an MMSI and an AIS name. The AIS name is made of up to 20 characters, which can be a combination of uppercase letters (A-Z) or numbers (0-9). The AIS name can be set by the user.
At regular intervals (every 5 minutes by default), the Petrel unit will perform a water sense check to determine if it is above water or submerged. If the check indicates that the unit is above water, it will exit Underwater Mode and return to GPS Search Mode.
Using the Magnet Switch The Petrel beacon is turned ON and OFF using an external magnet near an internal magnetic reed switch. The reed switch is located just below the glass. The Petrel will transition between on and off as appropriate when 4 consecutive magnet swipes occur within 2 seconds of each other.
Commands Below are commands for the Petrel. At this time, commands can only be sent over Bluetooth. • Each command starts with a dollar sign ($). The Bluetooth app pre-pends this automatically. • If a parameter is possible (marked with an X below), that parameter can be an integer to change the setting, or a question mark (?) to query the current settings.

Maintenance Battery Pack The power source for the Petrel is its battery pack. There are two battery pack sizes for the Petrel: Long Pack 7 Energizer LR20 D-Cell Alkaline 10.5V Short Pack 3 Saft LSH20 D-Cell Lithium 10.8V For Lithium models, only the Saft LSH20 has the ability to source enough current to supply peaks in Iridium transmissions.
O-Rings The Petrel has permanent O-rings installed in the head that are not meant to be replaced. The head of the Petrel proper is torqued at the factory to prevent accidental opening. The O-ring of the battery pack endcap is user-replaceable and should be visually inspected to make sure it is properly seated in its groove.
Warranty, Support and Limited Liability Xeos Technologies Inc. warranties the Petrel to be free of defects in material or manufacturing for a period of one year following delivery. Liability is limited to repair or replacement of the defective part and will be done free of charge.
