3 BASIC OPERATION ■ Frequency setting (Continued) D Selecting 1 Hz step You can change the frequency in 1 Hz steps for fine tuning. q P ush [TS] to turn OFF the Quick Tuning function. w H old down [TS] for 1 second to turn the 1 Hz tuning step ON or OFF. NOTE: • W hen RIT and/or ∂TX are used, they also tune in 1 Hz tuning steps. • The frequency changes in 50 Hz steps when the [UP]/[DN] switches of the microphone are used for frequency tuning (if the quick tuning function is not selected.) D Auto tuning step function When you rotate [MAIN DIAL] rapidly, the tuning speed can automatically accelerate, depending on the "MAIN DIAL Auto TS" option in the Set mode. q H old down [MENU] for 1 second to enter the Set mode. w P ush [Y](F-1) or [Z](F-2) to select "MAIN DIAL Auto TS." e R otate [MAIN DIAL] to select the HIGH or LOW tuning speed acceleration, or to turn OFF the function. • HIGH: W hen the tuning step is set to 1 kHz or smaller steps, the tuning speed is approximately five times faster. When the tuning step is set to 5 kHz or larger steps, the tuning speed is approximately two times faster. (default) • LOW : Approximately two times faster • OFF : Auto tuning step is turned OFF. • Hold down [CLR] (F-3) for 1 second to reset to the default value. r Push [MENU] to save, and exit the Set mode. D 1⁄4 tuning step function (Mode: SSB-D/CW/RTTY) The dial speed is reduced to 1⁄4 of the normal speed when the 1⁄4 tuning function is ON, for finer tuning control. You can set the 1⁄4 tuning function in each operating frequency band. This function is selectable only when the quick tuning function is turned OFF. q P ush [MENU] to display the "M1" screen (menu 1). w P ush [1⁄4](F-3) to turn the 1⁄4 tuning function ON or OFF. • " " appears when the 1⁄4 tuning function is ON. 39 [TS] [MAIN DIAL] 1 Hz step indication M1 AGC [∫] [√] DUP COMP TBW SCP [MENU] [MAIN DIAL] SET M A I N D I A L A u t o T S Ù 44 Ú HIGH HIGH (default) [1⁄4] [MENU] Appears M1
