List of Alarms
Alarms are reported on the receiver display screen. A blinking
warning sign appears on the status screen prompting you to
press the Scroll button so you can read the alarm label.
To acknowledge an alarm message once the alarm label is
displayed on the screen, press the Scroll button again. If
several alarm messages are reported, press the Scroll button
as many times. This will acknowledge each message, one
after the other.
If the reason for raising an alarm persists, you won’t be able
to acknowledge the alarm until you correct the problem.
Some of the alarms listed below can only be the result of a
bad serial command submitted to the receiver (in command
mode). Serial commands can be applied to the receiver from
FAST Survey or GNSS Solutions’ Wincomm Utility.
