SECTION 1 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 replaced 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 instructions for â��Purchasing the Latest SW STATION CALL ROMâ�� which are included with the unit. These ROMs can also be custom made to match the userâ��s particular combination of broadcast station frequencies. â�¢ 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. â�¢ Servicing is provided for the accessory Sony ROM. â�¢ Only the most recent version is supplied for replacing the Sony ROM. â�¢ A new Sony ROM is issued every year in October and the part No. suffix is also changed. â�¢ A new updated Sony ROM is issued every year so is not usually kept in stock. â�¢ Servicing is not provided for the F Corp. ROM. â�¢ Instruct the user to directly contact the F Corporation when the F Corp. ROM is obviously malfunctioning or defective. Address Mail : F Corporation P.O.
