ENVIRONMENT / OPERATING CONDITIONS
The End Device and wiDR monitor-controller are designed to be fixed mounted
and operated in a clean and dry environment. Care should be taken to prevent
the components of your wireless system from being exposed to moisture, toxic
chemicals, extreme cold or hot temperature that are outside the specification
listed in this manual.
The following is a list of basic good practice you should apply when operating
this Wireless System.
1. Do not operate the wireless wiDR in flammable or explosive
environments.
2. Do not use the wireless wiDR in medical, nuclear or other critical
application where failure can cause damage or harm.
3. Always operate the wireless wiDR within the recommended
environmental limits specified in the manual.
4. Do not operate the wireless wiDR with a battery or AC adapter other than
what’s supplied or specified in this manual or on the battery compartment
label.
5. Keep each wireless wiDR at least 8 inches (20 cm) from other radio
transmitters, antennas, and people.
6. The FCC approval for this wiDR specifies the specific antenna supplied
with this wiDR.
5.1 General Deployment Guidelines
1. Position wiDR in a central location. When multiple End Devices are in
operation, position your wiDR in a central space if possible in equal
distance to each End Device.
2. Test your system before permanent mounting. Try to move the devices to
different location around and mounting angles to determine what
installation achieves the best signal strength before permanently
mounting the End Device.
3. Move your system components higher off the floor and away from exterior
walls. The closer the End Device and wiDR are, the greater the
interference and lose of signal strength will be.
4. Maintain a line-of-sight between antennas and keep Fresnel zone free of
obstruction. See Figure 5.2.
5. Maintain a constant ambient temperature environment. Exposing your system
components to extreme cold or hot temperatures, or sudden changes in
ambient conditions will have an effect on the performance of your system.
6. As a general rule in buildings, head height or above is preferred. On the
other hand, an End Device which stays close to the floor may have its
range reduced by 50% to 90%.
