Loss of Settings When the Unit is Powered Off
C-Nav GNSS Receiver configuration parameter settings are stored in battery-backed RAM
(random access memory). The internal lithium battery has a 10-year life span. You can assume
the Lithium battery has failed when the receiver no longer retains configuration parameter
setting changes. Contact C-Nav Support for replacement lithium batteries.
All C-Nav proprietary software (C-Monitor, C-Setup) will retain any port configuration
parameters and GNSS configuration information when the power is turned off or removed.
