A wireless communications unit 200 , and corresponding method 300 within, is arranged and constructed for reducing peak current levels on a power source for the communications unit and comprises: one function, such as a transmitter 203 that is selectively enabled according, for example to an on/off duty cycle; an other function, such as a backlighting apparatus 214, 218 or accessory device 225 that is controllably supplied with a current where the current can be intermittently interrupted without adversely effecting utility of the other function; and a controller 209 for enabling the function or transmitter according to the on/off duty cycle and, when enabled, interrupting the current provided to the other function. |
