SERVICE NOTE
REPLACING THE SW STATION CALL ROM
The propagation of short-wave radio waves is greatly affected by
many causes such as atmospheric phenomenon due to dark spots on
the sun, etc.
This makes it necessary for short wave radio broadcast stations to
periodically change their broadcast frequencies. This set can be re-
placed with a new SW STATION CALL ROM to allow changing
the broadcast frequencies.
This set came with the latest ROM (Sony) when purchased. The
user can later on when needed, purchase the latest updated ROM (F
Corp.) version from the F Corporation on referring to the instruc-
tions for “Purchasing the Latest SW STATION CALL ROM” which
are included with the unit. These ROMs can also
be custom made to match the user’s particular combination of broad-
cast station frequencies.
• Identify the 2 different types of ROMs (Sony or F Corp.) as
follows.
The Sony ROM has no printing on it.
The F Corp. ROM is marked with the F Corporation name.
• Servicing is provided for the accessory Sony ROM.
• Only the most recent version is supplied for replacing the Sony
ROM.
• A new updated Sony ROM is issued every year so is not usually
kept in stock.
• Servicing is not provided for the F Corp. ROM.
• Instruct the user to directly contact the F Corporation when the
F Corp. ROM is obviously malfunctioning or defective.
