4 OPERATION s Filter setting When an optional filter is installed, set the optional filters in initial set mode. Optional filters are not selected by default. (p. 33) D Optional filter setting q While pushing and holding [SET], push [PWR] to enter initial set mode. w Push [UP Y] or [Z DN] several times until "FIL" appears on the display. e Rotate the channel selector to select the installed filter. • "no," "52A," "53A," "96," "222" and "257" indicate no optional filter, FL-52A, FL-53A, FL-96, FL-222 and FL-257, respectively for 455 kHz IF filter selection. r Push [PWR] for 1 sec. to exit initial set mode. D Expanded filter selection The selectable filter combinations can be expanded by setting the expanded filter selection to ON. Then extra wide or narrow filter can be selected on desired mode. q While pushing and holding [SET], push [PWR] to enter initial set mode. w Push [UP Y] or [Z DN] several times until "EXP FIL" appears. e Rotate the channel selector to turn the expanded filter selection 'on'. • If 'on' is selected, the expanded filter selection can be used. • Wide/narrow filter selection r Push [UP Y] several times until "WIDE TT" or "NAR TT" appears on the display. t Push [MODE] several times to se- lect the desired mode. y Rotate the channel selector to se- lect a filter. u Repeat steps t and y to select IF filters for other modes, if de- sired. •The filter combinations are stored depending on operating modes. • Wide filter setting table SSB no FL-52A FL-53A FL-96 FL-222 FL-257 no no no 96 (2.8 kHz) no 257 (3.3 kHz) THU (6 kHz) THU (6 kHz) THU (6 kHz) THU (6 kHz) THU (6 kHz) THU (6 kHz) no no no 96 (2.8 kHz) no 257 (3.3 kHz) CW THU (6 kHz) THU (6 kHz) THU (6 kHz) THU (6 kHz) THU (6 kHz) THU (6 kHz) no no no 96 (2.8 kHz) no 257 (3.3 kHz) RTTY THU (6 kHz) THU (6 kHz) THU (6 kHz) THU (6 kHz) THU (6 kHz) THU (6 kHz) - - - - - - AM • Narrow filter setting table : default SSB no FL-52A FL-53A FL-96 FL-222 FL-257 - no no - 222 (1.8 kHz) - 52A (500 Hz) 53A (250 Hz) - 52A (500 Hz) 53A (250 Hz) - 222 (1.8 kHz) - CW RTTY - 52A (500 Hz) 53A (250 Hz) - 222 (1.8 kHz) - i Push [PWR] for 1 sec. to exit initial set mode.
