1. A method, comprising:
coupling a messaging device to a computing device via a wired connection, the messaging device locally storing a plurality of messages in a memory of the messaging device and operational on a primary operational frequency and a secondary operational frequency;
subsequent to the messaging device being added to a message distribution group associated with a group Channel Access Protocol (CAP) code comprising a plurality of existing messaging devices that each are storing the group CAP code, receiving from the computing device a test communication transmitted to the computing device from the computing device through the wired connection to confirm the addition of the messaging device to the message distribution group, wherein the test communication is not transmitted to the plurality of existing messaging devices; and
when the test communication is successfully received by the messaging device, indicating receipt of the test communication by the messaging device.
