Built-in pull-up resistor. * CR Input: When the AC power supply is interrupted, the time counter switches to a holding state and a built-in oscillator promptly begins operation. If 50/60Hz input continues for 3 clocks without arriving, this oscillator’s output is activated and functions as the time counter clock in place of 50/60Hz input. The frequency level of this clock oscillator is determined according to the CR value. While the above mentioned oscillator is operating using backup mode, all segment output is switched to OFF. (Note) When the backup oscillator is in use due to an AC power supply interruption, the 50/60Hz input pin must be maintained open or at a VSS level. * 50/60 Selective Input: When 50/60 selective input is connected to VSS, 50Hz use is enabled. When 50/60 selective input is left open, VDD is activated using an internal pull-down resistor and the setting is switched to enable use at 60Hz. * Display Mode Selective Input (Alarm Select/Sleep Select): Since the pull-down resistor is built-in, selection from four display modes is possible using two SPST switches (single-pole and single-throw switches). Table 1 shows these display mode selections. Table1 Display Modes Selective lnput Alarm Sleep Display Mode Digit No. 1 Digit No. 2 Digit No. 3 Digit No.4 10’s place for Minute Minute 10’s place for Minute Hour VSS NC Alarm display Minute 10’s place for Minute NC VSS Sleep display Clear Hour Minute 10”s place for Second VSS VSS Second display Clear Minute Second Note: Activating VSS using two inputs simultaneously (alarm select and sleep select), the display mode is switched to display seconds. NC NC Time display 10’s place for hour, AM/PM 10’s place for hour, AM/PM Hour * Time Setting Input: There are two setting inputs for use with “hour” and “minute”. Time content settings show in Table2 are possible by activating VSS to these pins, A pull-down resistor is built-in.

Table 2 Setting contents Display Mode Set Input Functions Immediately adds 1 to hour digits and then assigns an additional 1, at a Hour speed of 2 Hz, after each 1/4 ~ 3/4 second. Immediately adds 1 to minute digits and then assigns an additional 1, at a Time Min speed of 2 Hz, after each 1/4 ~ 3/4 second. Seconds are rest. Both Operates both as outline above. Hour (note1) Second digits are cleared to [00]. Second Min Time holds. (Alarm & Sleep) Resets hour and minute digits as [0:00] when operating in 24-H mode or Both (note2) [12:00] when operating in 12-H mode. Immediately adds 1 to hour digits and then assigns an additional 1, at a Hour speed of 2 Hz, after each 1/4 ~ 3/4 second. Immediately adds 1 to minute digits and then assigns an additional 1, at a Alarm Min speed of 2 Hz, after each 1/4 ~ 3/4 second. Resets hour and minute digits as [0:00] when operating in 24-hour mode or Both [12:00] when operating in 12-hour mode. Sets sleep counter to [0:59] instantly when VDD is activated to sleep select Sets Sleep counter to [1:59] instantly when VDD is activated to sleep select Hour and hour at the same time. Sleep Min Sleep counter looses 1 at a speed of 2 Hz. Both Sleep counter looses 1 at a speed of 2 Hz. Notes: 1. Once conditions have been switched to reset or hold, input of other functions is locked until both Hour and Min input have been separated. 2. When the digital reading for seconds is between 30 and 59 seconds, 1 is added to the digits for minutes as he digital reading for seconds rests to [00]. * 12/24H Select Input: When this pin set open (VDD), a 12-hour display is enabled whereas connecting this pin to VSS enables the 24-hour display. A pull-down resistor is build-in. * Power Failure Detection Display: When activated by drop in power supply, all segments which are lit begin to blink and the unit switches to a power failure detection display. The power failure detection display is canceled by activating VSS to Hours set or Min set. * Alarm Operation and Alarm Output: The alarm signal outputs when alarm content matches the content of current time. When not rest by either snooze input or alarm off input, output continues after 1 hour and 59 minutes. This output signal consists of 900Hz 2Hz intermittent (50% duty) modulation signals, When the need arises, a filter can be applied to after the alarm signal to a DC signal. *Snooze Input: When the alarm is sounding and instantly activating VSS to this pin, alarm output is set to OFF for a period between 8 and 9 minutes after which time the alarm signal is once again output. The snooze function can be used repeatedly in 1 hours and 59 minutes intervals. A pull-down resistor is built-in Activating VSS to the snooze pin when the alarm is OFF resets the sleep timer counter to [0:00 ] (This is known as the one-touch sleep timer reset function.) *Alarm Off Input: Activating this input pin to VSS instantly sets alarm output to OFF.A pull-down resistor is built-in. *Sleep Timer and Sleep Output: Sleep output can turn on the radio and can be set for time intervals of 59 minutes or 1 hour and 59 minute. Refer to Table 2 for the proper selection procedure (59 minutes or 1 hour and 59 minute selection.) This sleep timer is constructed using a down counter and when the counter content arrives at [00], output is set to off and the radio turns off. Adding VSS to snooze input turns sleep output off. When sleep output is on.
