Getting started
Caution: Under extreme operating conditions, the
temperature of the rear heat-sink on this radio may
exceed normal surface temperatures.
Caution is advised to prevent possible skin burns.
Handsets
All the operating functions of the RS90 are carried out using the
handsets. Each handset contains a microphone, a small internal
loudspeaker and various buttons for controlling the radio.
Two types of handset are available:
•
Up to four wired handsets can be connected. There must be at
least one wired handset in the installation.
•
Up to two wireless handsets can be installed. The wireless
handsets communicate with the transceiver by 2.4 GHz radio
communication. The wireless handsets are powered by internal
rechargeable batteries, and are charged by inductive charging
when on the cradle.
When there are multiple handsets in operation, they are
synchronized so that there is no conflict of operation and they each
display the same information on their screens.
Handset naming
Handset names appear on screen at times—for example, when
another handset has control of the radio.
Wired handsets HS1, HS2, HS3, HS4
The above handsets—1 standard and 3 optional—are connected to
the transceiver. The volume controls on these handsets control the
corresponding external speakers.

Changing channel
Different jurisdictions in the world have allocated different sets
of VHF radio channels for different purposes. These sets are
known as channel banks. The available channel banks and their
corresponding channels are given in “Appendix 11 - US and ROW
VHF marine channel charts” on page 111.
You can switch the RS90 to any channel that is available in your
geographic area. Normally the radio is left tuned to the priority
channel (CH16 or CH09) in case an emergency call is broadcast on
that channel. The RS90 can also be set to monitor several channels
at the same time. In this case, the radio continuously scans the
selected channels and, if activity is heard on a channel, it will switch
to that channel while the activity continues. Then it will revert to
scanning. See “Scanning channels” on page 31.
You can use one of the following methods to change channel:
22 |
•
Press [16/9] to switch immediately to the priority channel (see
“Priority channels” below).

Receiving SAME alerts (US model only)
The NOAA All Hazards Weather Radio Service (NWR) works in
conjunction with the Emergency Alert System (EAS) to issue
weather alerts for specific geographic areas or weather warnings.
It uses a digital encoding system known as Specific Area Message
Encoding (SAME) to broadcast these alerts.
Each transmitter in the NWR network is identified with a unique
6-digit SAME code.
If SAME is enabled and the 6-digit country IDs you want to monitor
have been entered, the radio will sound the weather alarm when it
detects a weather alert on the selected weather channel.
For SAME alert setup, see “Setting up SAME alert” on page 78.
Receiving a SAME ALERT
If SAME ALERT is ON and an NWR or EAS alert for your geographic
area is broadcast, the RS90 detects the alert signal and sounds the
alarm.
Press any key to cancel the alarm.
•
If the alert is being sent by NOAA NWR, the radio automatically
tunes to the designated frequency so that you can listen to the alert.
•
If the alert is being sent by the EAS, the nature of the alert is shown
on screen as WARNING, WATCH, ADVISORY, or TEST.
Press any key to show the nature of the alert.
¼¼ Note: The list of alerts is shown in “Appendix 5 - Beep tones and call
alerts” on page 102.
Receiving SAME TEST messages
In addition to the WARNING, WATCH and ADVISORY alerts, the
EAS also send out TEST messages so that you can check that your
WX ALERT setup is working correctly. The TEST message is usually
transmitted between 1000 and 1200 (10.00AM and noon) every
Wednesday.
If your WX ALERT setup is working correctly, the alert sounds and
TEST is displayed on screen, followed by a broadcast message from
the National Weather Service.
¼¼ Note: If there is a threat of severe weather, the test will be
postponed until the next fine weather day.

DSC Procedures
DSC (Digital Selective Calling) is part of the Global Maritime Distress
and Safety System. It allows radio stations to contact each other on
a dedicated digital channel (channel 70). The radios automatically
exchange the digital contact and acknowledgement messages
on channel 70, freeing up the other VHF channels for voice
communications.
Once they have established contact, both radios automatically
switch to a VHF working channel for the operators to carry out
normal voice communication.
Each DSC radio has a unique 9-digit number, known as a Maritime
Mobile Service Identity (MMSI), which is used to contact that
individual radio.
DSC radios continuously monitor channel 70 irrespective of what
other channels they are working on. If someone calls your vessel via
DSC, your radio will sound an alert tone for you to respond to the
call.
If the RS90 radio is connected to a GPS system, it will automatically
send your location when calling other stations. This is especially
useful for distress calls.
DSC process
The calling and acknowledging process on channel 70 operates as
follows:
1. The calling radio transmits a DSC signal on channel 70.
2. Receiving radio(s) sound alert tones for their operators.
3. For individual, LL request and DSC test calls, the receiving radio
sends a DSC acknowledge signal on channel 70.
4. Both the calling and receiving radios switch to a working VHF
channel (except for LL request and DSC test calls).
5. Calling and receiving operators commence normal VHF voice
communications on the working channel.
6. Press [X] to return to standby mode.

Distress calls
DSC is particularly useful for sending distress signals to all stations.
The process is automated to the extent that if you are under stress,
you can simply press a single, dedicated distress button—the red
button beneath the red cover on top of the RS90 handset.
When sending a distress call, the DSC radio automatically transmits
as much information as is available, including:
•
The MMSI of the ship in distress;
•
The position of the ship in distress; (If the radio is connected to a
GPS);
•
The nature of the distress.
¼¼ Notes
•
Before the DSC functions can be used, you must enter a valid MMSI
into the RS90 radio. See “Entering or viewing your individual MMSI”
on page 81.
•
If the small DSC icon is not displayed on the standby screen,
DSC may have been turned off in settings. See “Enabling DSC
functionality” on page 84.
Soft Keys
A soft key is a name that appears at the bottom of the screen and
provides additional functionality to the [SCAN] and/or [OK] and/or
[3CH] buttons during DSC operations.
Dot symbols on the handset keys and just under the display screen
indicate which keys correspond to the soft keys as follows:

General process
When the radio receives a DSC call, it does several things as follows:
•
Sounds the alert tone to notify you of the call.
•
Displays a flashing
icon on screen, which indicates that a call
has been received and stored in the call log. When all call in the call
log and distress log have been viewed, the icon stops flashing. For
information on call logs, see “Calling using the call log” on page
52.
•
Displays the MMSI (or name) of the calling station. You can press
▲ and ▼ to view more details of the call, including the requested
working channel.
•
For individual calls, displays “AUTO SWITCH” or “NO AUTO SW,”
depending on the INDIV REPLY setting. It will automatically or
manually send an an acknowledgement to the calling radio and
switch to the requested channel.
•
For Group or All-Ships calls, displays “AUTO SWITCH” or “NO AUTO
SW,” depending on the Auto Switch setting.
With Auto Switch set to ON, when receiving a Group or All-Ships
call, the radio will automatically switch to the requested channel
if not cancelled within 10 seconds. This might disrupt important
communications that are already in progress on the current working
channel. To avoid this, you can prevent the radio from automatically
switching channel by setting the AUTO SWITCH option to OFF.
For information on setting the auto switch option, see “Automatic
channel switch options” on page 85.
The procedures for receiving calls with Auto Switch either on or off
are described below.
