Forced Connection and Transmission

It's possible to get the RF400 Logger to reconnect to a network and upload any unsent readings to the Comark
Cloud. To do this hold down the button on the front of the RF400 Logger and it will beep once. Keep the button
pressed until the RF400 Logger beeps again then release the button. This will force a connection and transmission.

Signal Strength

The RF400 Logger reports its current signal strength to the Comark Cloud
every time it communicates. It is possible to get real time signal strength
from the RF400 Logger to aid installation issues. To do this hold down the
button on the front the RF400 Logger and it will beep once. Keep the button
pressed until the RF400 Logger beeps two more times, then release the
button. The RF400 Logger will start beeping in relation to the signal strength.
Fast beeping is a good signal, slow beeping is a poor signal. In addition, the
LED on the button will flash green indicating a good signal, orange indicating
a medium signal and red for a poor signal. Press the button once more to
end signal test. Signal strength will only work if the RF400 Logger has been
set up to talk to the Comark Cloud. Signal strength test will automatically
end after 1 minute.
