6.2 How to change the frequency band
The frequency band can be set by firmware. Especially, if you want to use multiple CAIMAN-
PRO, special care is needed to avoid interference influence among the sensors. The available
frequency bands depend on the configuration and are listed in Table 6-4 through Table 6-5.
The allowed transmit power level and frequency bands depends on the used regions.
Regions for frequency approvals:
A1:
EU (incl. Belgian, Latvia), Norway, Iceland, Switzerland, Korea, Japan
B1:
USA, Canada
C1:
China
D1:
Turkey

To limit the effects of interference for two sensors facing each other, you should use different
Frequency IDs for each sensor on same PRF set ID. For a second pair of sensors facing each
other, the PRF set has to be increased by one. TMConfigurator PC software performs this task
for you. See Table 6-6 and Figure 28 for the basic principle with max. range configuration.

These

and will be reset to default after power down unless you save
them in the EEPROM by sending the “Save Parameter Setup” command:
