rev 1.0 july 15,2000 2 /8 ??ta?|3--?q ceramate technical co., ltd. cp8112b - l8sn24 function : a. on/off key : 1 st pressing on on/off is on, and 2 nd pressing is off. each pressing makes buzzer bi a sound. b. speed key : when fan works, it will automatically s tart at speed l and led l lights on. once speed key pressed again, from speed l to speed m, led l lights off & led m lights on. the next pressing is from speed m to speed s, and the following from speed s to speed l. the action l m s l m, accompanin g with led display & buzzer bi, makes a circulation. c. timer key : when time pressed, led 2h lights on as 2hr setting. when time pressed again, led 2h lights off & led 4h lights on as 4 hrs setting. timer action, as same as led display makes a cycle as of f 2h 4h 8h off. buzzer bi also sounds with each pressed key. led displays the remaining time. for example, when 6 hrs later, timer setting at 8 hrs, led 2h lights on & led 4h lights off. that is only 2hrs remained. then, the last 2hr later, all the led light off & fan off. d. rhy / slp key : fan is on, in the normal wind. upon rhy/slp key pressed, it turns to rhy and the led displaying the speed blinks. rhy/slp key pressed again, led slp, and led 8h light on. time set automatically at 8 hrs. time key offers the selection of time setting. but in the slp, timer automatically starts to set at 8h. each pressing makes buzzer bi a sound. e. osc key : when osc key is pressed, in fan?s working, osc works. the key pressed again, osc stops. each pressing makes the buzzer bi a sound. f. buzzer bi: 4kh z. g . oscillation frequency: 32.768khz . h . function of remote controller keys: same as above.
