transfer a message using the wireless communication interface to the computing device.

11. The messaging device of claim 8 , wherein the local operational frequency and the wide-area operational frequency are both within the range of 929-932 MHz.

12. The messaging device of claim 8 , wherein receipt of the test communication is indicated by at least one of a visual alert and an audible alert.

13. The messaging device of claim 8 , wherein the instructions, which when executed by the processor cause the processor to:

receive an update to a programming of the messaging device from the computing device via the coupling.

14. The messaging device of claim 13 , wherein the computing device is in communication with a host through a network connection and the update to the programming is received from the host by the computing device.

15. A method, comprising:

electronically coupling a messaging device to a computing device;

subsequent to the messaging device being added to a message distribution group comprising a plurality of existing messaging devices, receiving from the computing device a test communication through the coupling to test an operation of the messaging device and confirming the addition of the messaging device with regard to the message distribution group without communicating with the existing messaging devices;

when the test communication is successfully received, indicate indicating receipt of the test communication;

subsequent to the successful receipt of the test communication, operating the messaging device at a first operational frequency; and

determining a first filtered average received signal strength indication (RSSI) level of the first operational frequency based on a first plurality of measured RSSI levels, wherein only measured RSSI levels that are within a target RSSI range are included in the first plurality of measured RSSI levels.

16. The method of claim 15 , comprising:

incrementing the value of a first variable when the determined first filtered average RSSI level of the first operational frequency is above a first threshold RSSI level;

reducing the value of a second variable when the value of the first variable is at a first threshold value;

incrementing the value of the second variable when the determined first filtered average RSSI level of the first operational frequency is below the first threshold RSSI level; and

operating the messaging device at a second operational frequency when the value of the second variable is at a second threshold value.
