Disclaimer: Regular Testing
& Powering Off/On
You should test your SureSafeGO Plus Alarm at least once
a month to remain familiar with how it works, and to check
that it functions as expected. This can also alert you if you
unknowingly run out of credit, or if there is an issue with
your device.
Your SureSafeGO Plus Alarm should also be powered off for
3-4 minutes, before being powered on again, at least once a
month. This resets the onboard computer and helps ensure
the device will function correctly.
Failure to follow this process could result in the alarm not
functioning correctly when needed.
