Troubleshooting Guide
PROBLEM
SOLUTION
The Informer does
not activate when the
ON button is pressed.
Battery Polarity Reversed
– Verify the + and
– terminals on the battery match the markings
inside the battery compartment.
Low Battery
– Replace the battery.
The COMM STATUS
light is off and all
display values remain
at zero.
Weak Signal
– Ensure the Informer is aimed
directly at the unit’s infrared LED and is within
the operating distance.
Unit Not Transmitting
– Verify the unit is
energized and the green RUN light is illuminated.
Sunlight
- Verify the sun is not shining directly
onto the Informer’s infrared receiver or the unit’s
infrared LED.
The COMM STATUS
light is blinking.
Weak Signal
– Ensure the Informer is aimed
directly at the unit’s infrared LED and is within
the operating distance.
If using an older Informer (version 1.XX or
earlier), this is a normal condition.
The displayed values
fluctuate radically.
Weak Signal
– Ensure the Informer is aimed
directly at the unit’s infrared LED and is within
the operating distance.
The Informer
displays values even
after communication
is lost.
This is Normal
– The Informer holds the last
values it received before communication was
lost (until the auto shut off).
