12: Initial Check:
• Unfortunately this can not be completed easily with the CCARC FM92E’s supplied. So for the Tuesday
Nite Group, the Initial Check will be conducted by installing the 6 Meter Test EPROM. All other users of
this document should have a EPROM installed in their FM92E transceiver. Thus they should commence
the “initial check” as the first thing done. However be careful when checking the transmitter, do test it
into a shielded “Dummy Load”, for you do not want to interfere with a commercial operator on the
transmitter frequency.
• When you remover the covers from transceiver, do not loose or get mixed up with other transceiver top’s
& bottom’s. These covers normally have information on the EPROM’s.
• Plug in Test EPROM into FM92E [only for club members]. See chapter 38 “FM92E Test EPROM 68-88
Mhz Channel verses Frequency List:” and chapter 16 “EPROM Change:”.
6mtest1l.bin = Local Head Test EPROM 10.7 MHz IF.
6mtest2r.bin = Remote Head Test EPROM 21.4 MHz IF.
6mtest3l.bin = Local Head Test EPROM 10.7 MHz IF.
6mtest4r.bin = Remote Head Test EPROM 21.4 MHz IF.
• Check under one of the top or bottom covers for the list of frequencies, that was used originally by the
transceiver.
• Switch on Transceiver and check that it works ok. [ie lights work & mute works, etc].
• Go to the nearest Mhz of one of the frequencies [68 – 88 Mhz].
• Go to the channel Number for that Mhz on the chapter 38 “FM92E Test EPROM 68-88 Mhz Channel
verses Frequency List:” by the up/down buttons.
• With signal generator check that the receiver works.
• With the RF Power Meter check that RF power is being generated into dummy load & power meter.
• Switch off set if working ok.
• Remove EPROM.
• Plug in EPROM 6m1loc.bin, 6m2rem.bin, 6m3loc.bin, 6m4rem.bin, 6m5.bin, 6m6.bin,
6m7loc.bin or 6m8rem.bin See page 3 on “Files associated with this project”. to EPROM socket.
EPROM notch points away from hinges of Synthesiser board.
• Replace EPROM tin box over EPROM, 4 screws.
• Screw down the Synthesiser board.
• Replace cover for Synthesiser board side.
• Clean up FM92E transceiver. * This can be done at any time.
