Claim:
A method for controlling the operation of the wireless device, including: receiving an initial incoming signal from a remote device in a first operational mode, the initial incoming signal including information related to an initial remaining battery power in the remote device; determining that a second operational mode will be a first possible mode if the initial, remaining battery power in the remote device is within a first range; determining that the second operational mode will be a second possible mode if the initial remaining battery power in the remote device is within a second range; transmitting instructions to the remote device in the first operational mode to transmit and receive in the second operational mode: receiving an operational incoming signal from a remote device in the second operational mode after transmitting the instructions to the remote device, the operational incoming signal including information related to a revised remaining battery power in the remote device; determining that a third operational mode will be the first possible mode if the revised remaining battery power in the remote device is within the first range; determining that the third operational mode will be the second possible mode if the revised remaining battery power in the remote device is within the second range; and transmitting instructions to the remote device in the second operational mode to transmit and receive in the third operational mode.
