CONTROLS
FREQUENCY STEP CHANGE
A Tuning control
The frequency step automatically varies depending
on how fast the tuning control is turned. As the
control is turned more quickly, the frequency step
increases through the range of 5 Hz to 200 Hz. In
the FM mode, the range is from 50 Hz to 2 kHz.
B MHz button
Press this button to change the frequency in 1 MHz
steps using the UP or DOWN button. The
frequency step setting can be changed to 500 kHz
from 1 MHz. Refer to Menu Set-up for Menu B,
No, 62 on page 47. 1000 kHz is the default.
AMATEUR SUB-BAND SWITCHING
When the MHz indicator is off, you can cycle through
the sub-bands using the UP and DOWN buttons. The
transceiver switches to the next band in sequence as
shown below each time one of the buttons is pressed.
The most commonly used mode is selected
automatically for each sub-band.

RIT OPERATION
When the frequency of your contact shifts, you can
vary your receive frequency within + 1.1 kHz, without
changing your transmit frequency. Use this
procedure:
1 Press the RIT button.
The RIT indicator and the shift frequency value will
appear on the display right.

2 Adjust the RIT control to correct your receive
frequency. As the control is adjusted, the new
frequency shift updates both the RIT shift display
and the transceiver frequency display in 100 Hz
steps.
Although 100 Hz steps are displayed, the control
actually shifts the receiver in 10 Hz steps.
3 To switch off the RIT, press the RIT button.
The combination of + 1.1 kHz and 10 Hz steps
have been factory set, and may be changed to a
combination of + 2.2 kHz and 20 Hz steps. Refer
to Menu Set-up (Menu B, No. 63) on page 47.
It's a good habit to turn off RIT after a contact is
finished. This returns the receive frequency to the
transmit frequency. It ensures you don't listen by
mistake on a different frequency from your transmit
frequency on the next contact. When in the Memory
Channel mode, RIT only functions with a memory
channel containing stored data. RIT does not function
with an empty memory channel.
If extremely precise transmit and receive frequency
readout is required, the RIT display can display the 10
and 1 Hz digits of your frequency. Use Menu B, No.
67 through 70 to assign Special Function No, 86 ta
one of the microphone PF keys. Once assigned,
pressing this key causes the 10 and 1 Hz digits for the
transceiver frequency to appear on the display right
until the PF key is released. This display has priority
over the RIT display but there is no other effect on
RIT. Refer to Menu Set-up on page 47 and Special
Functions on page 49.
Although the minimum step size is 5 Hz, exact
frequencies to the nearest Hz are tunable by taking
advantage of fuzzy logic (refer to "Tuning control" on
page 16). If your desired frequency is not a multiple
of the current 5 Hz steps, turn the tuning control
slightly but quickly about the desired frequency.
Fuzzy logic temporarily alters the step size due to the
rapid tuning action. Now slowly tune the desired
frequency. One or two atternpts may be necessary to
select the correct multiple. You can select any
frequency to the nearest Hz by using this technique.
Note: When turning very slowly, a counting error of £1 step
may occasionally be observed. This is not a malfunction.
