1 GENERAL
1.1 Introduction
The RS81 and RS82 offer an extremely flexible approach to single and dual station VHF radios. The RS81 consists of an RS80B
transceiver “black box” with an AHS81 voice-only active handset with built-in loudspeaker. The RS82 utilises the same transceiver, but is supplied with an AHS82 DSC-enabled active
handset and separate external speaker. Both the AHS81 and
AHS82 are completely interchangeable and offer full intercom
facility between stations (Fig 1.1).
In any system combination that has an AHS82 handset the
radio will accept geographical position input via the proprietary SimNet data network, or via NMEA0183. Such a combination will also support iDSC interface with Simrad Chartplotters, enabling any DSC alerts to be displayed and acknowledged from the plotter itself.

The AHS81 and AHS82 have been designed with simple operation in mind for ease of use, even in installations that have one
station of each type. The handsets are fully waterproof and
designed for all environments from the navigation station to
the open cockpit.
1.1.1 About this manual
This manual combines operating and installation information
on both the RS81 and RS82 and is divided into four main parts.
As the handsets have differing layouts and functions are
accessed in different ways, we recommend that you familiarise
yourself with the information pertaining to the product that
you have purchased prior to installation or use. This will facilitate full understanding of the many operating features and
ensure straightforward installation.
Thank you for choosing Simrad.
If you are pleased with your VHF radio, we hope you will be
interested in our range of marine electronic equipment, which
is manufactured to the same high standards as the RS81/RS82.
Please contact your nearest Simrad agent for a catalogue showing our increasing range of high-tech navigational instruments,
GPS, Autopilots, Radar, Echosounders, Chartplotters and VHF
radio sets.
Simrad operates a policy of continual development and reserve
the right to alter and improve the specification of their products
without notice.

1.3 MMSI number
At the time of issue of your vessel’s radio licence, an MMSI
(Maritime Mobile Service Identity) number must be requested to
enable the operation of DSC functions. This is a nine-digit
number, which must be permanently entered into the RS82, or
RS81 with the DSC-capable AHS82 handset fitted.
NOTE If the boat, or the RS81 or RS82, is subsequently sold, the radio
must be returned to an authorised Simrad agent for the MMSI
number to be erased and the new owner’s MMSI number
entered.
An MMSI number will only be issued to licensed and certified
users. Please enquire with your local licensing authority for
full details.
Please refer to section 4.2.1 (RS81) or section 8.2.1 (RS82) for
information on how to enter the vessel’s MMSI number.
1.4 Group ID MMSI
For boats that are part of a flotilla, racing fleet or other group,
a Group ID MMSI number can also be entered, which will
allow DSC communication within the group, if DSC is available.
NOTE Contact your local authority for rules regarding Group MMSI
number allocation.
Please refer to section 8.2.2 for information on how to enter a
Group MMSI number. Please note, that the Group MMSI number
function is not available on the AHS81 handset.
1.5 ATIS number
Some countries require an ATIS number (e.g. Benelux and the
Rhine/Danube waterways); however, this option will only
appear on ATIS-equipped radios.
Please refer to section 4.2.2 (RS81) or section 8.2.3 (RS82) for
information on how to enter the ATIS number.
