Troubleshooting
If countdown does not start, check “Possible cause” and take corrective action referring to the table
below.
Problem
Possible cause
Action
Countdown does not
start when a hand is
held over the sensor.
The countdown time is not set.
Set the countdown time before using
the unit.
The non-contact sensor is not
yet ready to sense.
Upon completion of setting, wait for
at least five seconds (until the
"minute" and "second" light up)
before using the unit.
The non-contact sensor is
electrostatically charged too
strongly due to the
environmental conditions.
Upon installation of the unit, wait for
two minutes or so to allow the unit to
adapt to the surrounding conditions
before using the unit.
Remove the batteries, and then
reinstall them before using the unit.
