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-8900R to be tuned to-
ward 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-
8900R.
2 ) Direct Keypad Frequency Entry ( MH-48
Microphone)
The keypad of the MH-48
DTMF Microphone may be used for direct entry of the "Main"
A6J
band operating frequency.
To enter a frequency from the MH-48 keypad, just press the numbered digits in the
A6J
proper sequence. There is no "decimal point" key on the MH-48
keypad, so if the fre-
A6J
quency is below 100 MHz (e.g. 29.480 MHz), any required leading zeroes must be entered.
Examples: To enter 29.480 MHz, press [ 0 ] [ 2 ] [ 9 ] [ 4 ] [ 8 ] [ 0 ]
To enter 433.000 MHz, press [ 4 ] [ 3 ] [ 3 ] [ 0 ] [ 0 ] [ 0 ]
3 ) Scanning
From the VFO mode, press the [ SCN ] key momentarily to initiate scanning toward a higher
frequency. The FT-8900R will stop when it receives a signal strong enough to break through
the squelch threshold. The FT-8900R will then hold on that frequency according to the
setting of the "resume" mode (Menu #34 (SCAN); see page 65).
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-8900R is scanning. The scanning direction will be reversed. To revert to scan-
ning toward a higher frequency once more, rotate the DIAL knob one click clockwise.
Press the [ SCN ] key again to cancel scanning.
