Chapter 4 –Error Screens & Recovery
Error Screen
Explanation and How to Recover
Connection failed because Quasar is powered down, out of
range, or with an unsupported sensor type (ex. Pyro)
To recover try one of the following
Turn Quasar device on
Move closer to quasar
Turn quasar off, replace sensor, turn quasar on
Connection was lost
To recover enter the pairing code, as requested, and
continue
No sensor connected to Quasar
To recover connect a sensor to the Quasar and try again
Display is stuck showing 0000
This happens when the power reading is out of the sensor’s
range of measurement. There is nothing to do. When the
power comes within range, the measurement update will
resume.
