1 GENERAL
1.1 Introduction
The RS87 is a modular VHF radio and Class D Digital
Selective Calling (DSC) radio telephone system using a fully
featured telephone-style handset to access and control all func-
tions. It supports the latest GMDSS requirements for non-
SOLAS vessels from the International Maritime Organisation
(IMO). It will enable you to make digitally selected calls,
which are quicker and simpler to make than traditional voice
calls using Channel 16. Should a distress situation occur, with
the RS87 you can quickly raise an alert, indicating your identi-
ty, your position and automatically establish distress communi-
cation on the emergency voice channel.
The RS87 transceiver is robustly constructed using a pressure
die cast aluminium case for effective heat dissipation, ensuring
maximum transmission performance even after many hours
constant use.
Thank you for choosing Simrad
If you are pleased with your VHF we hope you will be interest-
ed in our range of marine electronic equipment, which is man-
ufactured to the same high standards as the RS87. Please con-
tact 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 operate a policy of continual development and reserve
the right to alter and improve the specification of their prod-
ucts without notice.

1.2 The Simrad integrated system
The standard RS87 radiotelephone can support up to two sta-
tions with full intercom facility, geographical position input
via NMEA0183 and iDSC integration with Simrad chartplotters
which enables the plotters to display DSC call information.
With the addition of the expansion board, the system can sup-
port an additional two stations, two intercom speakers and for-
ward and aft foghorn/loudhailer speakers in addition to the
standard functions.
Additional stations can either be another RS87 type telephone
handset, or an RS86 fixed panel display, with a passive tele-
phone handset or fistmike allowing great flexibility in installa-
tions (Fig 1.2) -

1.3 Licensing
NOTE Prior to use check the national licensing requirements for the
operator.
In the UK license applications and queries should be made to
the following authority -
Ship Radio Licensing
Radio Licensing Centre
The Post Office
PO Box 1495
Bristol
BS99 3QS
Aset may only be operated by, or under the supervision of a
holder of a Certificate of Competence and Authority to
Operate. This involves a simple examination and an annual
license renewal fee. The VHF only certificate is administered
by the Royal Yachting Association -
Royal Yachting Association
RYA House
Romsey Road
Eastleigh
Hants, SO5 4YA
Holders of the Restricted Certificate of Competence in Radio-
telephony (which covers MF/HF SSB etc), do not need a sepa-
rate VHF certificate.
In all other countries, please contact your regional authority for
information.

1.4 Entering MMSI numbers
At the time of issue of your vessel’s radio license, an MMSI
(Maritime Mobile Service Identifier) must be requested. This is
a nine digit number which must be permanently entered into
the RS87 when the radio is first set up, otherwise the DSC
functions cannot be accessed.
NOTE If the boat or the RS87 are subsequently sold, the radio must
be returned to an authorised Simrad agent for the MMSI num-
ber to be erased and the new owner’s MMSI number entered.
For European leisure vessels fitted with VHF DSC equipment, a
CEPT Short Range Certificate is required by the operator.
Additional requirements, such as GOC or ROC may apply to
operators on commercial vessels. Please enquire with your
local licensing authority for full details.
Refer to section 3.2.1 to enter the vessel’s MMSI number.
1.5 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. Refer to section 3.2.3 to
enter a Group MMSI number.

2. MAIN FUNCTIONS
2.1 General notes
Although it has many advanced features, the RS87 has been
designed to be as simple and intuitive to operate as possible.
The Shift key is used to access the secondary functions printed
above each key - press and release Shift, then press the appro-
priate key. These secondary functions are shown in this manu-
al in italics (eg Group).
NOTE The Shift key will automatically time out of Shift Mode after
two seconds if another key is not pressed.
At any time, pressing ON/C will cancel the current operation.
The lowest occupied port is the master controller - therefore
any operations initiated on this handset will override all other
stations.
CAUTION In order for other users to be able to operate the radio, it is
imperative that the handset is replaced in the cradle after use.
2.2 Switching on & Second Country mode
To turn the radio on, press the ON/C key. The display will
show the handset software issue number two seconds, then the
station number and software issue number for the transceiver
unit for two seconds.
As a default, the radio switches on tuned to the priority chan-
nel (normally 16). If Last Channel Used mode has been set (see
section 3.3.3) the radio will switch on tuned to the previously
used channel.
The radio stores the previous volume and squelch settings and
will use these on startup.
In countries where it is permitted, the RS87 can operate on a
secondary set of channels, such as the USA channels.
To select the secondary channel table, press Shift followed by
OK. The display will show the channel set selected for two
seconds before reverting to the default display.
NOTE Channels available will depend on programming. Please
enquire with your national licensing authority for details of
permitted channel sets in your own country.

Part No. E04297
Fig 2.1 - Selecting a channel
If the channel is invalid, the display will show “Invalid
Channel” and then revert to the previous channel.
The priority channel (normally 16) can be selected by pressing
16, which will also set the radio to 25W transmit power.
The preselected User Channel can be directly selected by press-
ing the User key. The display will show “U” next to the chan-
nel number to indicate that it is the User Channel (Fig 2.2).

2.3.1 Channel Sets
In addition to the standard International Channel, the RS87 can
also be programmed with regional Auxiliary Channels, such as
the marina channels M and M2 in the UK, the USA weather
channels and the fishing or leisure channels in Scandinavia.
To display the channel sets available, press Shift followed by
1W (Ch Set). Multiple presses of the 1W key while still in Shift
Mode will scroll through the available channel sets.

ing the marina channel set will automatically select it.
NOTE If no numeric keys are pressed within two seconds the radio
will revert to the previous working channel (except for marina
channel M as noted above).

2.4 Volume adjustment
To adjust the volume, press the VOL and VOL keys to
increase and decrease the setting respectively. Press and hold
the key to increase/decrease the setting rapidly.
The volume setting can be between 1 and 24 (loud).
2.5 Squelch adjustment

adjustment mode, then press the and (VOL) keys to
increase or decrease the squelch respectively. Press and hold
the key to increase/decrease the setting rapidly.
The squelch setting can be between 0 (open) and 10.
NOTE Squelch mode will automatically time out after two seconds if
another key is not pressed. Squelch mode can also be cancelled
by pressing the ON/C key.
2.6 Dual Watch mode
Dual Watch allows the radio to scan between the selected
working channel and the watch channel (the priority channel -
normally 16).
To enter Dual Watch, select the required working channel, then
press Shift and 3(DW) within two seconds.
If Dual Watch is selected while the handset is off cradle, the
display will show “Place back on cradle”. If the handset is
replaced within ten seconds of selecting Dual Watch, it will
automatically initiate Dual Watch when the handset is
replaced.
The display will show “D/W” - the large digits on the display
indicate the working channel, with the watch channel shown
below in small digits (Fig 2.5) -

Shift and then press and hold the 3(DW) for two seconds.
If Tri Watch is selected while the handset is off cradle, the dis-
play will show “Place back on cradle”. If the handset is
replaced within ten seconds of selecting Tri Watch, it will auto-
matically initiate Tri Watch when the handset is replaced.
The display will show “T/W” - the large digits on the display
indicate the working channel, with the user channel and watch
channel shown below in small digits (Fig 2.6) -
