Revision Menu walk through by hitting the menu button after each mode.
1. "RE/A24" – This is the Revision mode of the menu, it just tells you which
revision it is. This one is Revision A24. To get to this mode you will hit the
Test button till you see "RE/A24" should only take 1 or 2 clicks.
2. "REL/000" – This is the Relay mode. In this mode you will hit the up and
down button to simulate gas ppm reading to set the monitor off to make
sure they are communicating. This is one of the best troubleshooting tools
to use for our systems.
3. "rFl/###" – This is the Signal strength mode. It allows you to see a 3 digit
number that represents the signal strength from the head to the monitor. It
can read from 0-205 0=no signal and 205 = best signal. This is another great
troubleshooting tool just make sure not to leave it in this mode as it wears
out the batteries and it jams the monitor with constant messages.
