Turning off hearing mode?

i am using Z10 blackberry.
i mistakenly switched on the hearing mode and now i am not able to reach any icon directly but a voice tells me everything about the icon i touch.
i am unable to reach accessibility option in setting.
i cant drag down the list of icons in setting menu

please help me turning off the hearing aid

Press the power button three times quickly, pretty sure it tells you to do that in the Settings page of the screen reader.
