[. . . ] AVOID placing the transceiver against walls or putting anything on top of the transceiver. During mobile operation, DO NOT operate the transceiver without running the vehicle's engine. When transceiver power is ON and your vehicle's engine is OFF, the vehicle's battery will soon become exhausted. Make sure the transceiver power is OFF before starting the vehicle. [. . . ] RIT function can be used for the main readout only. TX function can be used for the transmit readout (main readout when the split function is OFF; sub readout when the split function is ON). 9 2. 4k TX 455 2. 8k USB 1ß 14. 100. 00 DUAL-W 12:34 USB VFO 21. 290. 00 USB 56ß VFO 14. 100. 00 21. 290. 00 USB · Scanning during dualwatch Scanning operates only for the main readout. To operate the scan during dualwatch, scan on the main readout and use the sub readout for your QSO using both dualwatch and split frequency operation. q Program the desired programmed scan edges in the same amateur band. 43 for programming. - If you plan to operate a F scan, programming the scan edges may not be necessary. t Push [DUALWATCH] for 2 sec. - The main and sub readout frequencies are equalized and the dualwatch function is turned ON.

The split frequency operation is basically performed using 2 frequencies on the main and sub readouts. Following is an example of setting 21. 290 MHz for receiving and 21. 310 MHz for transmitting. q Set 21. 290 MHz (USB) in VFO mode. ANT 1 METER Po Po P.
