Abstract
A battery powered electronic device (105) for coupling to a host computer (205 ) comprises an interface (115) for transmitting data and an annunciator (340) for generating a sensible alert. The electronic device (105) further comprises interface monitoring circuitry (320) coupled to the interface (115) for determining an interface status as being active or inactive and voltage monitoring circuitry (360) coupled to a battery (355) for monitoring the battery voltage. Threshold detection circuitry (360) coupled to the voltage monitoring circuitry (360) detects that the battery voltage has exceeded a predetermined threshold voltage and generates a low battery signal in response thereto. A controller (320) receives the low battery signal and, in response thereto, provides a low battery indication to the interface (115) when the interface (115) has an active status and provides an activation signal to the annunciator (340) when the interface (115) has an inactive status.
