Step 3: pairing code (made unreadable in the picture). On the smartphone: enter the code

Click Test alert. After a few seconds the test alarm arrives on your smartphone. If the button says “no alarm phone paired yet”, pair it first as described above.
Sound and full screen
The sound follows your phone
If your phone is set to silent, the alarm stays quiet. On vibrate it vibrates. On normal it rings once.
“Do not disturb”
If “Do not disturb” is on, the phone stays quiet. You then find the alarm in your notifications.
Full screen when the phone is locked
If your phone is locked, GEYRA shows the alarm large on the whole screen. That way you do not miss it.
When an alarm arrives
View the alarm
Your smartphone shows a notification from GEYRA, for example “Neues Gerät erkannt: …” (new device detected). Tap it.
Check
Do you know the device – a new phone in the family or a visitor? Then tap Kenne ich (I know it). If you want to look at it later, tap Später prüfen (check later). If you don't know it, block it: Block a device.

On the PC under Protection & system click MANAGE PHONES. Next to the old phone click REMOVE.
