Abstract
Various mechanisms are described for indicating to a user a low battery condition of a remote control for a controlled device. More particularly, a remote control detects a low battery condition as well as the replacement of batteries in the remote control. The remote control transmits a low battery message to a controlled device responsive to detecting a low battery condition. The remote control refrains from transmitting one or more subsequent low battery messages to the controlled device prior to detection of replacement of batteries. The remote control transmits a battery status message to the controlled device responsive to detecting the replacement of batteries in the remote control. The controlled device utilizes the low battery message and the battery status message to determine whether to present a low battery indicator to a user regarding a low battery condition of the remote control.
