4.1.2
Automatic Frequency Selection Function
This JAX-9B is designed to automatically select a frequency in the good receiving condition from all
frequencies that are broadcasted from the same broadcasting station.
If the receiving condition of a selected frequency becomes worse gradually, the equipment will
automatically select another frequency in the good receiving condition.
For using this function, it is required to register more than one frequency which broadcasts a fax
broadcasting of the identical contents simultaneously in the frequency channels of a same group.
1) Setting Procedure
Register all frequencies of a broadcasting station that you desire to record in the frequency channels
of a same group. For example, when choosing the fax broadcasting of JMH automatically, the
receiving frequencies are registered as follows.
(When registering in the group channel 00)
•
Register 3622.5 kHz in the frequency channel 01.
•
Register 7795.0 kHz in the frequency channel 02.
•
Register 13988.5 kHz in the frequency channel 03.
•
Do not register any frequencies in other frequency channels (04 to 09).
MEMO
JMH is the name of the facsimile broadcasting station under the control of
Meteorological Agency of Japan.
The frequencies shown above are the JMH broadcasting frequencies as of March 2008.
NOTE
The FAX broadcasting from a desired broadcasting station cannot be received if the
frequencies of another broadcasting station are registered in the same group channel.
Do not register different broadcasting stations in the same group channel.
