displayed in the handset display). The DC input fuse must be rated at 10 amperes middle
slow for a 12V system and 5 amperes for a 24V system.
The power supply in the below deck unit provides galvanic isolation from the ships DC
power system. The secondary side of the power supply must be firmly grounded to the
vessel body through a short low impedance wire from the grounding screw terminal on the
below deck unit.
Remote Turn-On
The system can be configured for remote turn-on by connecting the ignition detection input
on the 6 pole PTR screw connector to a special generator output or another desired power
control circuit. With the ignition detection connected the system will turn on whenever a
voltage higher than 10V is present on the input (primary referenced).
External Speaker
Using the external speaker socket will automatically disconnect the handset cradle speaker.
If an external speaker is used it must have an impedance of 8 Ohm. The external speaker
output is balanced, hence the outer conductor is not grounded.
Extra Ringer
An output for an external ringer is available on the 6 pole PTR screw connector. The ringer
output is an RS-410 open-collector output with the return wire connected to secondary
ground. When using an external ringer make sure that the ringer provides galvanic isolation
from vessel ground.
Radio Mute
An output for radio mute is available on the 6 pole PTR screw connector. The mute output is
an RS-410 open-collector output with the return wire connected to secondary ground. When
using the radio mute function be sure that the radio provides galvanic isolation from vessel
ground.

NSTALLATION
The handset and cradle must be installed in a protected dry area. The cradle connects to the
main unit through a single cable and provides all main operation interfaces to the system.
The handset is held in the cradle with a magnet, the cradle can then be mounted in any
practical orientation.
