Setting the Carrier Keying
Keying dials on the carrier must be used to assure that the correct module type
will be installed on that carrier. One dial selects alphabetic characters and the
other selects numbers. These dials must be set to match the factory keying on
the underside of the module. Refer to Appendix D for module keying
assignments.
