FM MONO switch / ind icato r Normally this is set to the off position (the FIV MONO indicator go-‚¬s off). When noise spoils the reception of an FM program, pr6Es the switch to the on position (the Fl\4 MoNo indicalor will now light). The program ofan FM stereo broadcast will be heard in mono. The setting of tho FM MONO swrtch (on or off) is momorized along with the station's frequgncy in the STATION CALL swrtch9s.When using the preset tuning feature, reception will be in the mode selected wh6n lhe station was memorized. This switch will nol function tor AM (MW or LW) reception. FREOUENCY display Pormits roading thg received frequency at a glance trom lhe display6d figris. The FM band is indicated by MHz, and the AM (MW or LW) band by kHz. TUNING switch This is used to locate the stations. Push either side of this switch; the left side "-" to go to a lower, and the right side " + " to go to a higher lrequency. STEREO indicator This lights wh6n a stereo program has been picked up during an FM broadcast. SELECT (1 -1 2 11 3-241 switch/indicator This switch is used to s6l-‚¬ct th6 STATION CALL switches to Mode 1 (1-12) or Mode 2 (13-24). Mode 2 (13-24) is ob- tained when tho switch is oressed 8nd select indicator i8 lit. NOTE: Changing the position ol this switch has no ellect on rcceivet peiomance itself. TUNED indicator This lights to indicate wh-‚¬n the finost tuning of a station has b6en achieved. STATION CALL switches These are used to recall preset broadcasting stations and to preset the statton. BAND SELECTOR switch IFor modol F-X882] Each time this switch is pressed, FM or AM reception is selected alternately, FM and MHz lightr FM reception AM and kHz light: AM reception lFor model F-X88ZLl Each time this switch is pressed, FM, MW or LW recep- tion is selected slternatelv. FM and MHz light: FM reception AM and kHz light: MW or LW reception MEMORY switch This switch is used to memorize stations. When the switch is pressed, the frequency indicator will flash. To memorize the frequency of any station, press the station call switch while rhe memory indicalor is lit. 3
