q
C (-31 to
140
q
F).
Additional Indoor Site Requirements
The following requirements guarantee proper operation of the system:
• For IDU-C units, allow at least 90 cm (36 “) of front clearance for
operating and maintenance accessibility. Allow at least 10 cm (4 “)
clearance at the rear of the unit for signal lines and interface cables
• The ambient operating temperature should be 0 to 50°C (32 to 122
°F) at a humidity of up to 90%, non condensing
Stage 3: RF Survey
The RF survey examines the wireless environment of
WKH1HWURQLFV
installation site, to determine whether there are available channels within
WKH1HWURQLFV
operating frequency band. An RF survey is performed
using a spectrum analyzer.
It is advisable to familiarize yourself with the spectrum analyzer before
going out on site, specifically the Max Hold and Marker functions.
You should perform the RF survey at both proposed link sites.
The survey should be carried out during a busy time of day, to best judge
the worst-case radio interference. Allow 2-4 hours duration for a good RF
survey.
Note
It is possible to install the
1HW6WUHDP
link and use the Link Manager to
find a clear channel. Each frequency channel can be evaluated in turn.
Achievement of a clear channel is indicated by the Quality bar on the
Channel Setting window (see
figure 4-13
) becoming green.
