Alarms and Messages
The radio may generate the following alarms or system messages.
Battery Alarm
If the radio detects a voltage greater than 15.8 Vdc or less than 10 Vdc, “HIGH VOLTAGE”
or “LOW VOLTAGE” is displayed on the screen. Check the wiring if any of these
conditions occur.
Main in Use
When the primary VHF 200 or VHF 200i unit is being used, “MAIN IN USE” is displayed
on the screen of all remote GHS 10 or GHS 10i handsets. The screen returns to normal three
seconds after the last input on the primary station.
Remote handset stations cannot interrupt the primary radio unit. However, remote handset
stations can interrupt the operation of other handset stations.
WX (Weather Alert)
If you set the WX alarm and an incoming weather alert is detected, the radio automatically
tunes to the WX channel that is broadcasting the alert. See page 12 for more information on
weather alerts.
GPS Data Alarm
When GPS data from a NMEA network or position data you entered manually is over four
hours old, the alarm tone beeps and “DATA IS OVER 4 HOURS OLD” is displayed on the
screen.
Select IGNORE to disregard the alarm and to turn off the alarm beeping. When you take
no action after three minutes, IGNORE is selected automatically.
Select SET to enter a new position. See page 27 for more information on manually
entering position data.
Invalid GPS Data Alarm
When GPS data from a NMEA network or position data you entered manually is over 23.5
hours old, “DATA IS INVALID” is displayed on the screen. The radio will not transmit
position data that is more than 23.5 hours old.
Select IGNORE to discard the old position data. The screen displays “NO GPS INFO”
on the Home screen. When you take no action after three minutes, IGNORE is selected
automatically.
