If there is no operation in 5s, then return to time display. 6. Clock mode Key function illustration 1) CLOCK Press this key less than 1 second, it will display time, and return to previous state if no operation in 5 seconds; Press this key more than 1 second, it will enter clock setting mode, HOUR flashes, and it can be adjustable through UP, DN key. Press the CLOCK key again confirms the clock setting. It will return to previous state if no operation in 5 seconds; Power on reset, before time setting, the COLON does not flash, only flashes after clock setting. 2) ALARM1/ALARM2 When ALARM closed, press this key less than 1 second, the ALARM1 or ALARM2 turns on, display the ALARM time. If the boot-strap is set in CD mode at this time, it will switch to display CD music number from alarm time displayed if no operation in 5 seconds, and it will return to previous state after 5s. "ALARM" is light when alarm function on; When ALARM1 or ALARM2 turn on, press this key can cancel ALARM function, and the "ALARM" light off. Press the ALARM1 or ALARM2 more than 1 second, enter alarm setting mode, ALARM hour flashes. The time can be adjusted through UP, DN keys, press the ALARM again confirm the alarm function; If the boot-strap is set in CD mode at this time, it will enter alarm power on music selection function, and CD flag flashes, the power on music can be adjusted through UP, DN key. If there is no operation in 5 seconds, it will return to previous state and clear the ALARM symbol. Music selection range: 1-30, if the selected music No. is more than the MAX number, then play the first one; In the power off mode, alarm will ring if time to the set value: if it is in the AUTO step, it will play CD in

CD mode; if there is no disk, CD open, or read fail, it will output BUZZ sound; if it is in TUNER step, it will play radio and display time; if in the BUZZ step, then output BUZZ. In boot-strap mode, alarm will ring if time to the set value: if it is in the AUTO step, it will play CD according the ALARM set music in CD mode; if there is no disk, CD open, or read fail, it will output alarm; if in the BUZZ step, then output BUZZ, at this time press AUTO/BUZZ key can switch to output MUSIC or BUZZ; press POWE or ALARM can shut down power after alarm, and cancel the alarm function; When alarm ring, the corresponding ALARM1 or ALARM2 flashes, and press the corresponding key can cancel the alarm function, ALARM light on and power off; It will power off after ALARM ring in CD mode, and close BUZZ output after 5 minutes in BUZZ mode. Unless pressing the ALARM or POWER key, the one hour timing can be cleared. ALARM has memory function, and it can be cleared after power on again. ALARM1 operating frequency is 600Hz; ALARM2 operating frequency is 1200Hz. 3) SLEEP Press SLEEP to power on and play the CD automatically. After set SLEEP, the first press SLEEP key will display the time, press this key again will set the SLEEP time over again. SLEEP sets the time as 90-80-70-60-50-40-30-20-10-0After 0 minute it will cancel SLEEP mode. The SLEEP flashes when set the time, and after the timer is open, display SLEEP. 4) SNOOZE When the alarm rings, press this key to enter SNOOZE mode, and after 6 minutes, the alarm clock will ring again. 5) UP Time increases 1, and it will continue increase when press the key continually. 6) DN Time decrease 1, and it will continue decrease when press the key continually. 7. Radio mode In radio mode, display the frequency, and it will return to time display if no operation in 5s; when the frequency is changed, switch to frequency display automatically. 1) FM frequency display

8. BUZZ mode In power on mode, judge the AUTO/BUZZ state first, if it is in BUZZ state, then output buzz; In AUTO state, if it is in CD state, then interrupts the CD state, and jump to play the setting music; if it is in radio state, it is remained. In power off mode, judge the AUTO/BUZZ state first, if it is in AUTO state, power on automatically; if it is in CD state, then jump to the setting music and play automatically; if it is in BUZZ state, output buzz. After alarm, press ALARM or POWER will return to power off state.
9. POWER OFF Display clock in power off mode

HANDLING MOS DEVICES:
Electrostatic charges can exist in many things. All of our MOS devices are internally protected against electrostatic discharge but they can be damaged if the following precautions are not taken: * Persons at a work bench should be earthed via a wrist strap. * Equipment cases should be earthed. * All tools used during assembly, including soldering tools and solder baths, must be earthed. * MOS devices should be packed for dispatch in antistatic/conductive containers.
Note: Silan reserves the right to make changes without notice in this specification for the improvement of the design and performance. Silan will supply the best possible product for customers.
