Operating Environment
The Skymetry WTU-14 should be mounted and operated in a
clean, dry environment. The unit must communicate to the wireless
network, so care must be taken not to install the unit inside a metal
cabinet or other location that will prevent the unit from receiving
a radio signal unless the antenna can be relocated to a location
free of obstruction. The unit is microprocessor-controlled and, as
a result, should not be installed near devices that generate strong
electromagnetic fields. Such interference is typically generated by
power switching equipment such as motors, contactors, or variable
frequency drives. Where this is unavoidable, mount the unit in a
separate, grounded steel enclosure with an external antenna (see
Appendix F: Accessories). A poor operating environment may result
in unwanted system resets and/or system lockup. The temperature
range the unit can operate in is -20°F to 158°F (-29°C to 70°C).
Activating your Skymetry WTU-14
Your Skymetry device must be activated on the wireless network
before you can send or receive messages and before any local pro-

To activate your Skymetry WTU-14 device, fill out the activation
form included with the package and follow the instructions, or con-

"Registered" LEDs are lit.
