Personnel Alert: Base Station
Radio Frequency (RF) Optimization
Single Base Station System: For systems that require only
one base station, any dip switch setting can be used on S2.
Multi Base Station Systems: For systems consisting of
more than seven base stations, the risk of interference is
minimal when using the recommended Honeycomb pattern
setup mode. The optimum layout for multi base station
systems is the Honeycomb pattern. Refer to
Area System
Planning and Figure 5.Honeycomb Pattern.
The numbers in each hexagon represent the decimal
equivalent for the dip switch setting that should be used for
switch S2. Maintain a record of the pattern that is selected for
each base station to ensure that settings are not duplicated
for adjacent base stations. Refer to Table 6 for an example.

a Caution
For multi-base station installations, ensure that adjacent
base stations do not have the same hopping pattern, as
interference will result.
The following Table 7. Frequency Hopping Pattern
represents the decimal to binary conversion for the dip switch
S2 settings. 0-6 and 7=1 (Zoltan)

Adjusting the Transmit/Receive Attenuation
Levels
Area coverage of the base station can be controlled by
adjusting the transmit/receive attenuation levels in the base
station to match the actual radio coverage area that was
determined during the area system planning.
The attenuation adjustments are also used to tune the
amount of coverage overlap between base stations.
