19 FT -2800M O PERA TING M ANUAL C HANNEL S TEP S ELECTION Tuning steps are factory preset to default increments which are appropriate for the country to which this radio is exported. Y ou may have a reason to use a different step size, however, and here is the procedure for changing the channel steps: 1.
20 FT -2800M O PERA TING M ANUAL RF S QUELCH A special RF Squelch feature is provided on this radio. This feature allows you to set the squelch so that only signals exceeding a certain S-meter level will open the squelch.

21 FT -2800M O PERA TING M ANUAL A DV ANCED O PERA TION R EPEA TER O PERA TION The FT-2800M includes a host of convenience features which makes operation on amateur repeaters both efficient and enjoyable.
22 FT -2800M O PERA TING M ANUAL A DV ANCED O PERA TION [ 2 ] Automatic Repeater Shift The ARS (Automatic Repeater Shift) feature in this transceiver allows easy and convenient repeater operation by automatically activating the repeater shift function whenever you tune to a standard repeater subband.
23 FT -2800M O PERA TING M ANUAL A DV ANCED O PERA TION [ 3 ] Separate Transmit Frequency Memories (“Odd Splits”) All memory channels can store independent receive and transmit frequencies, to accommo- date occasional non-standard offsets with greater frequency resolution than is available us- ing the “standard” shift feature.
24 FT -2800M O PERA TING M ANUAL CTCSS/DCS O PERA TION CTCSS Operation Many repeater systems require that a very-low-frequency audio tone be superimposed on your FM carrier in order to activate the repeate r . This helps prevent false activation of the repeater by radar or spurious signals from other transmitters.
25 FT -2800M O PERA TING M ANUAL Y our repeater may or may not re-transmit a CTCSS tone - some systems just use CTCSS to control access to the repeate r , but don’t pass it along when transmit- ting.
26 FT -2800M O PERA TING M ANUAL Tone Search Scanning In operating situations where you don’t know the CTCSS tone or DCS code being used by another station or stations, you can command the radio to listen to the incoming signal and scan in search of the tone being used.
27 FT -2800M O PERA TING M ANUAL CTCSS/DCS O PERA TION A DV ANCED O PERA TION CTCSS/DCS Bell Paging During CTCSS Decode or DCS operation, you may set up the FT-2800M such that a ring- ing “bell” sound alerts you to the fact that a call is coming in.
28 FT -2800M O PERA TING M ANUAL DTMF A UT ODI ALER O PERA TION Nine DTMF Autodialer memories are available on th e FT-2800M .

B ASIC S CANNER O PERA TION Before activating the scanner, make sure that the Squelch is set to silence the background noise when no signal is present.
35 FT -2800M O PERA TING M ANUAL M EMOR Y S KIP S CANNING When you have some continuously-active channels in memories, you may wish to skip them for scanning , but still have them available for manual selection . To mask a memory to be skipped during scanning, use the following procedure: 1.
36 FT -2800M O PERA TING M ANUAL P REFERENTIAL M EMOR Y S CAN The FT-2800M also allows you to set up a “Preferential Scan List” of channels which you can “flag” within the memory system. These channels are designated by a blinking “ SKIP ” icon when you have selected them, one by one, for the Preferential Scan List.
37 FT -2800M O PERA TING M ANUAL P ROGRAMMABLE B AND -S CAN L IMITS Besides band and memory scanning, this transceiver can be set to tune or scan only the frequencies between user-defined lower and upper limits. For example, you may wish to limit tuning/scanning to 144.
38 FT -2800M O PERA TING M ANUAL P RIORITY C HANNEL S CANNING ( D UAL W A TCH ) The FT-2800M ’ s scanning features include a two-channel scanning capability which allows you to operate on a VFO, Memory channel, or Home channel, while periodically checking a user-defined Memory Channel for activit y .
39 FT -2800M O PERA TING M ANUAL B AND E DGE B EEPER The FT-2800M will automatically “beep” when the receiver ’ s band edge is encountered during scanning (either in standard VFO scanning or during PMS operation).

42 FT -2800M O PERA TING M ANUAL 7. Rotate the DIAL knob, while pressing and holding in the [ ] ke y , to select the DTMF access number (“ DTMF-1 ” ~ “ DTMF-9 ”) corresponding to the Internet link repeater to which you wish to establish an Internet link.
43 FT -2800M O PERA TING M ANUAL The FT-2800M may be used for 1200 bps Packet operation, using most all commonly- available Terminal Node Controllers (TNCs). Connections between the transceiver and the TNC are accomplished via the front panel Microphone connector and rear panel External Speaker jack, per the diagram belo w.
44 FT -2800M O PERA TING M ANUAL T IME -O UT T IMER The “Time-Out Timer” (TOT) feature is designed to force the transceiver into the “receive” mode after a preset time period of continuous transmission (the default is 6 minutes).
45 FT -2800M O PERA TING M ANUAL M ISCELLANEOUS S ETTINGS P ROGRAMMING THE K EY A SSIGNMENTS Default FT-2800M key functions have been assigned to the Microphone ’s [ P1 ] / [ P2 ] / [ P3 ] / [ P4 ] buttons at the factor y . These may be changed by the user, if you wish to assign quick access to another function.
46 FT -2800M O PERA TING M ANUAL MIC G AIN C ONTROL You can reduce the microphone input level when operating on tightly-clustered frequencies (channel spacing of 12.5 or 15 kHz). This will reduce the transmitter deviation, thus mini- mizing interference to other users.
47 FT -2800M O PERA TING M ANUAL In some instances of erratic or unpredictable operation, the cause may be corruption of data in the microprocessor (due to static electricit y , etc.). If this happens, resetting of the micro- processor may restore normal operation.
