1. An electronic messaging device, comprising:
- a receiver configured to receive a message at an operational frequency;
a controller operatively connected to the receiver;
a memory operatively connected to the controller and configured to store a message received by the receiver, a value of a first variable, and a value of a second variable; and
a power source configured to supply electrical power to the controller; and
wherein the controller is configured to;
operate the receiver at a first operational frequency;
determine a first filtered average received signal strength indication (RSSI) level of the first operational frequency, wherein the first filtered average RSSI level is based on a first plurality of measured RSSI levels;
increment the value of the first variable and reduce the value of the second variable when the value of the first variable is at a first threshold value when the determined first filtered average RSSI level of the first operational frequency is above a first threshold RSSI level; and
operate the receiver at a second operational frequency when the value of the second variable is at a second threshold value.

Abstract
An electronic messaging device includes a receiver configured to receive a message at one of a first operational frequency and second operational frequency. The messaging device can operate using a time synchronous protocol and can receive commands through over-the-internet-programming (OTIP) and over-the-air-programming (OTAP).
