PHYSICAL LOCATION OF THE FRG-7700
 
The FRG-7700 will perform well in any location that allows free passage of air around the cabinet. Solid state equipment such as the FRG-7700 should not, however, be used in extremely hot environments unless some provision is made (external fan, etc.) for keeping the station temperature less than 40°C.
 
INTERCONNECTION WITH YR-901 MORSE CODE/TELETYPE READER
 
The YR 901 is a high performance computerized translator which will allow display on a video monitor of incoming Morse Code and/or teletype (RTTY) signals. The YR-901 and YVM-1 Video Monitor are options available from your Yaesu dealer.
 
Complete operation instructions are included with the YR-901. Please refer to the drawing below for details of the extremely simple interconnection required. Please note that the SP-901 speaker is not mandatory for use with the YR-901, as the latter includes a built in speaker.
 
The YR-901 will allow you to see for yourself late breaking teletype news as it comes from abroad on circuits used by the international news services. Amateur radio Morse Code and teletype communications, and a host of other exotic transmissions will unfold before you on the video screen. See your Yaesu dealer for details.
