I can't find a mute button on my doro 660 - Doro Lands Phones

SOURCE: I cannot tell if/where the mute button on my doro 626ez cell phone

in the top line of controls , tap the left selection key and tap select settings from the menu, tap left selection key, select sound, tap left selection key, select silent and tap the left selection key, select on (or off which ever you want) and tap left selection key
(when you turn on silent mode , all phone sounds are turned off) tap disconnect to return to home screen
I am wondering how you are going to read this if you are blind
