2 INTRODUCTION
The RS81 is a modular VHF radio system with a user friend-
ly, remote-style handset to access and control all functions.
The RS81 transceiver “black box” is robustly constructed
using a pressure die-cast aluminium case for effective heat
dissipation, ensuring maximum transmission performance
even after many hours constant use.
The dual station RS81 radio system has been designed for
countries in which DSC capability is not a requirement. It is
ideal for leisure and light commercial use and can support up
to two handsets. Additional stations can either be another
AHS81-type handset, or a DSC-capable, fully-featured AHS82
radio-telephone handset. The RS81 offers full intercom facili-
ty and allows optional geographical position input via NMEA
(if the second handset is an AHS82).
The operation of the AHS81 handset, which has an inbuilt
loudspeaker, is designed to be simple and intuitive. Large
buttons and a rubber-profiled handle-back ensure safe and
comfortable handling, whilst the large, backlit LCD allows
easy reading, even in difficult conditions.
The handset is tough and waterproof, and is designed to
withstand the rigours of the marine environment.
3 MAIN FUNCTIONS
3.1 General notes
Packed with many advanced features, the Dual Station RS81 is
compact and has a contemporary look and feel.
The S
HIFT key is used to access secondary functions printed in
small letters below the main function on the key – simply press
S
HIFT, then select the appropriate key. Secondary functions are
shown in this manual in brackets, e.g. (S
CAN M).
NOTE The S
HIFT key will time out of Shift mode after 2 seconds, if
another key is not pressed.
The handset plugged into Station 1 is the master controller.
Operations initiated on this handset will override all other sta-
tions. When a handset is lifted off its cradle, the other handset
will display “OCCUPIED”. If a press and hold operation is ini-
tiated on a handset, the other will display “IN USE” and func-
tions will not be accessible.
When entering or editing text in any of the displays, the cursor
position is indicated by a flashing dash.
