An electronics device (“ED”) includes a housing, a buttons electrical circuit block, at least one user operable button in operable communication with the buttons electrical circuit block, a microcontroller block, and a first-time-on (FTO) electrical circuit block, disposed within the housing. The FTO electrical circuit block includes an activation node and a signal reception contact, and is configured: (i) to place the ED into a deep power conservation mode (“DPCM”) upon either the direct application of an electrical signal to the activation node by an ED or a deactivation signal received at the signal reception contact; (ii) to terminate the DPCM and place the ED into a normal operating mode upon receiving a predetermined user triggered signal from the at least one user operable button; and (ii) to generate the deactivation signal received at the signal reception contact in response to an external command signal received by the microcontroller block.

A method for wireless transmission of data between a master controller (2, 2′) having a receiver (10) and a transmitter (9), and at least one slave device (3) having a receiver (19) and a transmitter (18), and to a corresponding blood glucose system (1, I1). The slave device (3) is normally operated in a power saving mode in which its receiver (19) is only activated intermittently at a receiver activation frequency for a predetermined listening period. The controller (2, 21) transmits a communication initiation data frame to the slave device (3) by means of a signal comprising a preamble signal transmitted for a preamble period. Upon receipt of the communication initiation data frame, the slave device (3) is switched to a communication mode in which it transmits a response to the controller (2, 21), and the slave device (3) is switched from the communication mode to the power saving mode.
