3.4 Power consumption

Following table shows an approximate overview of power consumption of mobile terminal HW 90196 at

different operating states (BIOS terminal:‘09905, firmware radio module: #09907). The measured values

during operation depend on the current accumulator voltage. The measurement has been taken with an

accumulator voltage at 3,8 V while discharged accus provoke higher currents. The operating status of the

radio module has a significant influence of the overall power consumption of terminal HW 90196. In par-

ticular, if the terminal is switched off or outside radio frequency range (see No. 8, 12, 6, 4, 2), program-

ming should meet these conditions, e.g. by switch off with bios_sleep() (see No. 13) after time out. Also, if

no optical warning can be indicated on switched off display of terminal (see No. 11 & 12) and radio con-

nection is still running after a time out, the terminal should be completely switched off by bios_sleep()

(see No. 13).
