Auto Tuning Step function
When you rotate [DIAL] rapidly, the tuning speed can
automatically accelerate, depending on the “MAIN
DIAL Auto TS” setting in the Set mode.
q
Hold down [MENU] for 1 second to enter the Set
mode.
w
Push [
Y
](F-1) or [
Z
](F-2) to select “MAIN DIAL
Auto TS.”
e
Rotate [DIAL] to select the HIGH or LOW tuning
speed acceleration, or to turn OFF the function.
• HIGH : When the tuning step is set to 1 kHz or
smaller steps, the tuning speed is approxi-
mately five times faster.
When the tuning step is set to 5 kHz or
larger steps, the tuning speed is approxi-
mately two times faster. (default)
• LOW : Approximately two times faster.
• OFF : Turns the function OFF.
• Hold down [F-3] for 1 second to reset to the default set
-

About the 5 MHz frequency band operation (only USA version)
Operation on the 5 MHz band is allowed on 5 discrete
frequencies and must adhere to the following:
• The USB mode
• Maximum of 50 watts ERP
(Effective Radiated Power)
• 2.8 kHz bandwidth
It’s your responsibility to set all controls so that trans-
mission in this band meets the stringent conditions
under which amateur operations may use these fre-
quencies.
NOTE:
We recommend that you store these fre-
quencies, mode and filter settings into memory
channels for easy recall.
* The FCC specifies center frequencies on the
5 MHz band. However, the transceiver displays car-
rier frequency. Therefore, tune the transceiver to
1.5 kHz below the specified FCC channel center
frequency.
Transceiver Displayed

To assist you in operating the 5 MHz band within the
rules specified by the FCC, transmission is illegal on
any 5 MHz band frequency other than the five fre-
quencies shown in the table above.
