OK.

Troubleshooting Guide – Factory Default Configuration

9 Key => NV,-1 comes up in A0 – Alerts tab for receiver confirmation.

9 GPS Receiver’s LEDs blink.

9 After 10 seconds, cycle power (Turn OFF and then ON) the GPS receiver.

 Although the receiver has already been software cycled, it is always better to do a power

cycle to ensure the reciever goes through the complete boot-up process.

9 Establish communication through COM2, which is default Control Port (the default baud rate has been

reset to 19.2K).

9 The almanac and ephemris are reset. Let the GPS receiver track satellites and navigate for more than 30

minutes to download a new almanac. Although it only takes 12.5 minutes to gather the almanac, if the
satellite providing the data is setting, the almanac will be incomplete. This is why a 30 minute period is
recommended.
