Tuning Dial
Rotating the
DIAL
knob allows tuning in the pre-programmed steps. Clockwise rotation of the
DIAL
knob causes the
FT-2900R
to be tuned toward a higher frequency, while counter-clock-
wise rotation will lower the operating frequency.
Press the [
MHz
(
SET
)] key momentarily, then rotate the
DIAL
knob, to change the frequency
steps to 1 MHz per step. This feature is extremely useful for making rapid frequency excursions
over the wide tuning range of the
FT-2900R
. Instead of pressing the [
MHz
(
SET
)] button, you
may also press the [
A
] key on the Microphone’s keypad to engage tuning in 1 MHz steps.

Direct Keypad Frequency Entry
The keypad of the
MH-48
A6J
DTMF Microphone may be used for direct entry of the oper-
ating 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. However, there is a
short-cut for frequencies ending in zero: press the [
#
] key after the last non-zero digit.

If you cannot get the radio to accept the frequency entry, it is possible that the
channel steps are set to an incompatible value (e.g. if you have 25 kHz steps set,
you cannot set a frequency of 146.520 MHz). See page 19 to learn how to change the
channel step size.

Scanning
From the VFO mode, press the microphone’s [
UP
]/[
DWN
] keys momentarily to initiate
scanning toward a higher- or lower frequency, respectively. The
FT-2900R
will stop when
it receives a signal strong enough to break through the squelch threshold. The
FT-2900R
will then hold on that frequency according to the setting of the “Resume” mode (Menu “

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-2900R
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.
Press the [
UP
]/[
DWN
] keys again to cancel scanning. You may also press the
PTT
button
momentarily; scanning will stop, but you will not transmit until you release the
PTT
button,
and press it again.
If you have enabled the “Severe Weather Alert” feature, you will occasionally no-
tice “WX” channels interspersed with the regular channels you are scanning. This
is normal, because your radio is constantly monitoring for weather alerts. See page 17.
