BX SXX This indicator specifies the beam to which the radio has logged-on, as well as the radio received signal strength (i.e. B1 S55). Beam mapping is as follows:
Beam 1 East Central Beam 2 West Central Beam 3 West Beam 4 South Beam 5 Alaska/Hawaii
Signal strength ranges from 0 (no signal) through 99.

actions and functions
various functions
BUTTONS (Mobile Units)
Power: The power button is the
“on-off” switch for the handset. It is a “delayed action” button – you must keep it pressed for a second
initiate the power on or power off sequence.
PTT: Pressing and holding the
PTT button initiates and maintains a Dispatch Radio call.
P1: Pressing this key initiates a
Priority-1 Emergency Interruption Dispatch Radio call.

PHYSICAL KEYS
Keypad Keys: The keypad
contains alphanumeric keys for text entry and Circuit-Switched Voice number dialing.
SEND: This key is used to
initiate the Dial-out Dispatch sequence.
END: This key is used to Quick
exit from any menu through which you are navigating. When you press the key you are returned to the “idle” display screen

UP /DOWN ARROW:
These keys are used primarily for the following functions:
1) Volume adjustment 2) Scrolling through various menus 3) Scrolling through downloaded talk group tag positions
When you first enter the Main Menu, the system lock is OFF.
highlight LOCK: OFF, then press SELECT to lock the
changes to LOCK: ON. HAND SET LOCK AND UNLOCK
select the LOCK: ON
At the prompt for the unlock code, type in the code and then select Enter
The option then reverts
back to LOCK: OFF. The default code is 0000 (four zeroes).
Idle: This is a typical view of
the screen when the unit is activated and not in use.
Calling: This indicates the
PTT has been depressed and the unit is requesting an open channel thru the satellite.
USER ON: This indicator
appears when the PTT key has been pressed and the communication channel has been accessed. The indicator is prompting you to begin speaking.
VACANT : This indicator
appears when the PTT key has been released. It indicates that the communication channel is available to any member of the talk group who wishes to speak.
DN: This number appears
person speaking, when the unit is in operation.
Status or Event Sound Notes
Radio Info Message Two quick high tones Indicates one of the following: Hardware failure Satellite link is lost (no service could be network failure). Lost Speaker Two quick high tones Indicates that the current party speaking has been cancelled and the radio has stopped transmitting. Call Termination Sounds like a “fast busy” tone Sounds when the call is terminated because of the disconnection of satellite link. Calling Failure Tone Sounds like a “fast busy” tone Indicates that a Circuit Switched call has failed during call set-up. “USER ON” – Talk Ready A short high/Low tone Indicates that the user can begin to talk in Dispatch Radio mode. Talk group Vacant A low tone Indicates the talk group is available. Power On / Power Off A short high tone Indicates the radio has been powered on/off. Incorrect Key Two quick beeps When a key is pressed out of sequence.
Error Condition Definition Action Searching….
If signal strength bars are seen, the radio is in the process of connecting to the MSAT network. If signal strength bars are not seen, the radio cannot receive a satellite signal. If the condition persists, check the radio has a clear view of the southern sky and that the antenna is connected and is functioning (e.g. can hear the servo motor in the antenna).
Wait….
Signifies that the radio has not received a response to the PTT request from the MSAT network and is attempting several retries. Continue to press the PTT key. If the call is successful, USER ON will be
FAIL message will appear requiring the user to release the PTT key and try again
PTT Fail
Signifies the radio failed to receive a response to the PTT request from the MSAT network. Release the PTT key and try again. If this message continues, contact MSV Customer Support.
Press PTT
Signifies the PTT key was been pressed then released just before the radio received the confirmation from the network. Press and hold the PTT key in order to talk.
Invalid DN
Signifies the user has entered a Directory Number (DN) that is not a member of the private mode talk group currently active on the radio. Ensure a valid DN is entered in tag position 00.

Signifies the user has entered the wrong Handset Lock code. If you cannot remember the lock code (default is 0000), enter the SYSTEM password (default 1234) when prompted to enter the code.
ANTENNA FAILURE
This indicates the radio has detected a fault in the antenna and shut it down. Power cycle the radio. If this problem persists, contact MSV Customer Support.
Antenna Failure: This indicates the radio has detected a fault in the antenna and shut it down.

Signal Strength
The signal strength is seen in
values from 00-99, during heavy thunder storms you may see below 25 which may give you less than optimal performance.
This displays the Channel that you are currently on.
