battery life. Only perform a test
once before each dive trip
This equipment is intended for
emergency use. Do not activate
unless in an emergency situation.
Dive cap should remain sealed

Each Nautilus GPS comes pre-programmed with an MID number. This number
serves as your identification and will be transmitted along with your distress call.
The number can be found on the back label of your Nautilus GPS.
If your vessel (or the vessel you are traveling with) has a DSC enabled VHF radio, it
is recommended to program the vessel MMSI number into your Nautilus GPS. This
allows your Nautilus GPS to send a DSC position report directly to the vessel VHF
radio by holding down the yellow button for 5 seconds.
Note: Not required for use of the red Help button

and Nautilus GPS will transmit a low power Routine Own Ship Position Report.
This message will be received by all surrounding vessels with AIS receivers. As well, if you
have programmed a vessel MMSI (see page 7), the message will be received on the vessel’s
VHF radio.

REWINDING ANTENNA
To rewind the antenna, after use of the Nautilus GPS, use the tool provided in the box. Pass
the end of the antenna through the slot of the rewinding tool. Insert the tool into the open
space of the top cap. Continuously turn the tool clockwise to fully spool the antenna back
into place. Remove the tool and replace the antenna retainer.

How to install batteries
Unscrew two screws
on top cap Insert two batteries Put screws back
The batteries should be replaced per the battery
vendor's expiry date as printed on the batteries
and recorded on the back label or after TEST
mode battery change notice (alternating RED and
Yellow LEDs). Replacing the batteries requires a
Philips #1 head screw driver and a clean, non lint
surface. We recommend using Panasonic
CR123A 3V batteries. Lower quality batteries
