10. Plug the AC/DC power supply into an AC power
source. Instrument and modem should power on.
11. The LED on the modem will blink while the modem
searches for a suitable network. If the LED stops
blinking and is solid blue, a network has been found
and proper communication with Environet™ should
be possible. If the LED changes to solid yellow, the
modem has not found a network. A power cycle may
resolve the issue or the unit may need to be moved
to a different location where signal strength is
improved.
