INTERNET CONNECTION FEATURE
DTMF tone is sent at the
beginning of every
transmission
The FT-8800R can be used to access the repeater which is
configured to provide access to the Vertex Standard WIRES™
(Wide-Coverage Internet Repeater Enhancement System).
1. Tap the “left” VOL knob momentarily to activate the
WIRES™ access capability. The “INT ON” will appear for
2 seconds at the “Main” band frequency display. The “int”
icon will appear in the memory channel field on the “Sub”
band while WIRES™ access is enabled.
2. Rotate the “Main” band DIAL knob, while pressing and
holding in the “left” VOL knob, to select the access number
(ICODE “0” - “9,"A,” “B ,” “C,” “D ,” “E (*),” or “F (#)")
corresponding to the WIRES™ repeater to which you wish
to establish an Internet link (ask your repeater
owner/operator if you don't know the access numbers in the
network).
3. With the WIRES™ capability activated (as in step 1 above),
the FT-8800R will generate a brief (0.1 second) DTMF tone
according to your selection in step 2. This DTMF tone is
sent at the beginning of every transmission to establish or
maintain the link to the remote WIRES™ repeater.
4. To disable the WIRES'™ access capability; tap the “left”
VOL knob again.

TONE SEARCH SCANNING
~ You must be sure that your repeater uses the same tone type
(CTCSS vs. DCS).
~ Some repeaters do not pass the CTCSS tone; you may have to
listen to the station(s) transmitting on the repeater uplink (input)
frequency in order to allow Tone Search Scanning to work.
To scan for the tone in use:
1. Set the radio up for either CTCSS or DCS Decoder
operation (see the previous discussion). In the case of
CTCSS, “ENC DEC” will appear on the display; in the case
of DCS, “DCS” will appear on the display.
2. Tap the [SET] key momentarily to enter the Set mode.
3. Rotate the “Main” band DIAL knob to select Menu #40
(TONE F) when CTCSS is selected, or Menu #10
(DCS.COD) during DCS operation.
4. Press the “Main” band DIAL knob to enable adjustment of
the selected Menu Item.
5. Tap the “Main” band [SC N] key momentarily to start
scanning for the incoming CTCSS or DCS tone/code.
6. When the radio detects the correct tone or code, it will halt
on that tone/code, and audio will be allowed to pass. Tap the
“Main” band DIAL knob momentarily to lock in that
tone/code, then press and hold in the “Main” band DIAL
knob for 1/2 second to save the new setting and exit to
normal operation.
♦♦ If the Tone Scan feature does not detect a tone or code, it
will continue to scan indefinitely. When this happens, it may be
that the other station is not sending any tone. You can press the
[SC N] key to halt the scan at any time.
Tone Scanning works either in the VFO or Memory modes.

HOME Channel Memory
1 Select the desired frequency, while operating in the VFO
mode on the “Main” band. Be sure to set up any desired
CTCSS or DCS tones, as well as any desired repeater offset.
The power level may also be set at this time, if you wish to
store it.
2 Press and hold in the [SET] key for 1/2 second. A memory
number will appear (blinking) on the display.

will now be stored in the special HOME channel register.
4 You may repeat this process on the other operating bands.
5 To recall the HOME channel, just press the [H/M] key while
operating either in the VFO or MR mode.

switches and DIAL knobs may be locked out.
To activate the Lock feature:
1. Tap the [SET] key momentarily to enter the Set mode.

(LOCK).
