Large phone keypad<br />
Make phone calls simply by tapping entries in your contacts and favorites lists. When you need<br />
to dial a number, the large numeric keypad on iPhone makes it easy. See Make a call on page 51.<br />
LED Flash for Alerts<br />
If you can’t hear the sounds that announce incoming calls and other alerts, you can have iPhone<br />
flash its LED (next to the camera lens on the back of iPhone). This works only when iPhone is<br />
locked or asleep.<br />
Turn on LED Flash for Alerts. Go to Settings > General > Accessibility > LED Flash for Alerts.<br />

You can have the audio of incoming or outgoing calls automatically routed through a headset or<br />
speaker phone instead of iPhone.<br />

choose how you want to hear and speak your calls.<br />
You can also have audio from calls routed to your hearing aids; see Hearing aids on page 165.<br />

someone from leaving a session), and turn on Touch ID (as a way to end Guided Access)<br />

Tap Time Limits to set a sound or have the remaining Guided Access time spoken before<br />
time ends<br />
