Out-Of-Range Alert - Sony A1ll User Manual

21.2

Out-of-range alert

When the distance between A1ll and the device causes a disconnection, A1ll
will warn the user with vibrations. Due to the uncertainties of connectivity
and signal strength it is impossible to set a fixed distance.
The function will be set to OFF in AHA per default.
Design rationale: Users that are in their home or when working in an area
that is quite big will not want to be reminded of having left their phone
behind as this has been done intentionally. If the user get's reminded of this
s/he will probably feel that the bracelet disturbs rather than helps.
Out of range alert is disabled when do not disturb is on.
