1) Tuning Dial
Rotating the DIAL knob allows tuning in the pre-programmed steps established for the current
operating band. Clockwise rotation of the DIAL knob causes the FT-8800R to be tuned
toward a higher frequency, while counter-clockwise rotation will lower the operating frequency.
operating band. Clockwise rotation of the DIAL knob causes the FT-8800R to be tuned
toward a higher frequency, while counter-clockwise rotation will lower the operating frequency.
On the “Main” band frequency, press the DIAL knob momentarily, then rotate the DIAL
knob, to change the “Main” band frequency steps to 1 MHz per step. This feature is ex-
tremely useful for making rapid frequency excursions over the wide tuning range of the FT-
8800R.

2) Direct Keypad Frequency Entry (MH-48
A6J
Microphone)
The keypad of the MH-48
A6J
DTMF Microphone may be used for direct entry of the “Main”
band operating frequency.
To enter a frequency from the MH-48
A6J
keypad, just press the numbered digits in the
proper sequence. There is no “decimal point” key on the MH-48
A6J
keypad.
Examples: To enter 146.480 MHz, press [1]
[4] [6] [4] [8] [0]
To enter 433.000 MHz, press [4]
[3] [3] [0] [0] [0]
3) Scanning
From the VFO mode, press and hold the [SCN] key for one second, then rotate the DIAL
knob to select the bandwith for the VFO scanner. Now, press the [SCN] key momentarily to
initiate scanning toward a higher frequency. The FT-8800R will stop when it receives a
signal strong enough to break through the squelch threshold. The FT-8800R will then hold
on that frequency according to the setting of the “resume” mode (Menu #34 (SCAN); see
page 66). See page 39 for details regarding the VFO Scan operation.

If you wish to reverse the direction of the scan (i.e. toward a lower frequency, instead of a
higher frequency), just rotate the DIAL knob one click in the counter-clockwise direction
while the FT-8800R is scanning. The scanning direction will be reversed. To revert to
scanning toward a higher frequency once more, rotate the DIAL knob one click clockwise.

scanning toward a higher frequency once more, rotate the DIAL knob one click clockwise.
Press the [SCN] key again to cancel scanning.
