・PRECAUTIONS




                                      WARNING
               Do not touch Transmitter/ Receiver.
               Transmitter/ Receiver is a moving part, and it may cause injury.
               For internal inspection and repair work of equipment components,
               consult with our branch office, branch shop, sales office, or our
               distributor in your district.


      This transmitter must not be co-located or operated in conjunction with any other antenna or
transmitter.
This device complies with Part 90 of the FCC rules.

 Soli-State Radio Module     GKP-2781


1.General

       GKP-2781 is sloid-state radio module of compact weather radar. It is composed with STALO,
 Signal Processor, and Transmitter/Receiver Module. The source oscillation signal is generated in
 Signal Processor. Transmitter/Receiver up-convert the source oscillation to the transmission
 frequency by mixing it with the local signals generated in STALO.
       Since this is solid-state type, it does not require either pre-heat or tune-up. Also, it is possible
 to keep stable transmission and low power consumption for longer period of time.


       Details of the components are shown in the next page.
