Transducers with Fixed Frequency 7 Troubleshooting

Transducers with Fixed Frequency
Sometimes it is preferable or necessary to set fixed frequencies for the transducers. In this case, the base
station is set to automatic channel search. When a transducer is docked in a slot, the base station recognizes
that the transducer is set to a fixed frequency, and allocates that frequency to the transducer.
The setting of fixed frequencies is done using the Service Support Tool ( only after consulting Philips
Support). Refer to the Service Support Tool Help for details.
Transducers with fixed frequencies have the following advantages:
• They are particularly suitable for use with antenna systems.
• They are particularly suitable in large installations, where you can avoid interference problems between
the large number of telemetry systems or other RF interference sources.
• They make it easier to prevent the Avalon CTS system from interfering with other RF devices.
• They make it easier to interchange transducers between different base stations.
Do not assign the same frequency to more than one transducer.
Note that in case of repair, transducers with fixed frequencies cannot be exchanged so easily.
Transducers for Japan
Transducers for Japan must use fixed frequencies. They are initially shipped from the factory with no
frequencies assigned to them. During installation, they are initialized, and their frequencies are set. This
can only be done once, and if it needs to be done again, an access code must be obtained from the factory.

Service Support Tool Help for details.
Multi-Region Base Station
The Multi-Region base station is a special version of the the ISM band base station, using only restricted
RF channels within the broader ISM band.
Delivery Status
The base station receiver is ‘disabled’ at the factory before shipment. If you dock transducers in a base
station in this disabled state, the base station will not assign any frequencies to them. The tranducer display
will show a blinking
warning message.
Installation
You need to enable the base station during installation using the Service Support Tool.
Set the correct frequency channels using the Service Support Tool (see the Service Support Tool Help for
details).
Choose the appropriate country from the drop-down menu of available (non-standard) countries. As you
do this, the Service Support Tool automatically determines the relevant frequency ranges to allocate and
exclude.
