5 FUNCTIONS FOR RECEIVE ■ AFC operation (Mode: FM/DV) AFC stands for Automatic Frequency Control. The AFC function tunes the displayed frequency automatically when an off-center frequency is received. q Push [AM/FM] or [DV•DR] once or twice to select the FM or DV mode. w P ush [MENU] to display the "M1" screen (Menu 1). e P ush [AFC](F-3) to turn ON the AFC function. • " " appears when the AFC function is ON. The AFC limit can be set in the Set mode. (p. 164) While the AFC limit is ON, AFC stops tuning when the received frequency exits the frequency limit range. The optional UT-121 is required for DV mode operation. [AFC] [MENU] [AM/FM] [DV•DR] ■ RIT function The RIT (Receive Increment Tuning) function compensates for off-frequency operation of the received station. The function shifts the receive frequency up to ±9.99 kHz in 10 Hz steps*, without changing the transmit frequency. *The [RIT/∂TX] control tunes in 1 Hz steps when the operating frequency readout is set to the 1 Hz step readout. However, the 1 Hz digit is not displayed on the frequency shift readout. q Push [RIT] to turn ON the RIT function. • "RIT" and the frequency shift appear when this function is ON. w Rotate the [RIT/∂TX] control. • Hold down [CLEAR] for 1 second to reset the RIT frequency. • Push [CLEAR] momentarily to reset the RIT frequency when the quick RIT clear function is ON. (p. 164) • H old down [RIT] for 1 second to add the frequency shift to the operating frequency. e To cancel the RIT function, push [RIT] again. • "RIT" and the frequency shift disappear. D RIT monitor function When the RIT function is ON, holding down [XFC] allows you to listen to the displayed frequency (RIT is temporarily cancelled). 69 [RIT] [CLEAR] [RIT/∂TX] control Appear M1 AGC DUP COMP TBW SCP [XFC]
