1.4 Password Protection:

The CGR provides a number of screens for the pilot to use during flight, none of which require a password. It
also provides many System Configuration Screens that are used to configure the CGR for a specific aircraft.
Fuel level, if installed, must be calibrated during installation before the aircraft is flown.

The CGR provides three levels of passwords for configuring and calibrating the unit.

1.4.1

1.4.1 User Password:

User Password:

The User Password is for the pilot or operator of the aircraft. This password allows the pilot to perform
the following:

A. Adjust the K-Factor for the fuel flow.
B. Set the Local and Zulu Clocks.
C. Setup some Bar Graph limits.
D. Download recorded flight log data and change recording sample rate.
E. Set the Recurring Fuel Alarm.
F. Backup Config Files.
G. Change or disable the User Password.
H. Set Com3 and Com4
I. Set the Voice Level and test a Voice File.
J. Perform the Input/Output Tests.
K. View a Function and Probe Configuration.

By default the User Password is blank, if left blank you will not need to enter a password to access these
features. If the CGR installed in an aircraft that is primarily owner operated we recommend leaving the
password blank. However, if this aircraft is used by renters or students, we recommend setting a pass-
word to keep unauthorized changes from happening.
