models, ensure the lens and window of the ceilometer are clear by gently wiping them with a soft microfiber
lens cloth. To prevent moisture accumulation on the lens, gently wipe the provided Rain-X

wipe around the
lens in a circular motion to apply an even coat of the hydrophobic solution.
Special Battery Warning
In fast reporting mode or areas with little sun exposure and extreme cold temperatures, the MWS will need
to be charged to at least 5 V for extended full operations under these conditions. Please note that the
charging process could take up to 24 hours, so operation checks before installation are highly
recommended.
When your MWS is plugged in to hardline power with the “DATA” port (on the front of the unit, pictured
below), the system charges via a power and data cable over USB. As a result, the raw data voltage reading
is slightly higher than when it is unplugged. If the first report back from your MWS when not connected to
hardline power provides a low battery voltage (below 5 V), change the reporting mode to every 3 hours until
the battery is charged to over 5 V. If operating in limited sun exposure or there is a need to use the 5-minute
reporting mode, keep in 3-hour mode until the battery is charged to at least 5.5 V. Overall, monitoring the
MWS battery pack voltage over time and environmental changes will ensure system availability and limit
downtime due to low battery levels.
Cellular Signal Strength (Cellular Models Only)
Approximately 30 seconds after powering up, the unit will attempt to connect to the cellular network tied to
the factory-installed SIM card. After those 30 seconds, the LEDs will illuminate a second time to indicate the
signal strength at the current location.
Single LED flashing
– No signal or SIM card not activated; the MWS will not report remotely without
cellular signal or activated SIM card.
Solid LEDs (one, two, or three)
– The number of LEDs illuminated indicates the signal strength from
low to high. As long as a signal is indicated, the MWS will report data automatically.
