APPENDIX D
The GPS 126/128 uses a flashing on-screen message
indicator to alert you to important information. Whenever
the message indicator appears, press PAGE to view the
message page. There are two types of messages: temporary
alerts and condition alerts. Temporary alerts are cleared
from the message page after viewing, while condition
alerts remain until the condition has been resolved. Pay
careful attention to all messages for your own safety.
