(1) Function
This pin has the following functions.
RADIO OUTPUT pin (pin 22) output control
Alarm output stop control
Sleep operation setting (including setting the operating time)
(2) Operation
RADIO OUTPUT pin output control
The output of the RADIO OUTPUT pin can be controlled by applying a high or low level to the MANUAL &
SLEEP pin. The operations of applying a high or low level to this pin for over 20 msec and under 0.5 seconds are
abbreviated as “an ON input” and “an OFF input” in the remainder of this section.
The operations performed on an ON input are as follows:
— The RADIO OUTPUT pin output is made active, i.e., the pin 22 output goes to the high level.
— Any alarm operation either in progress or interrupted by the snooze function is stopped.
— “On” is displayed in the LEDs.
Figure 17 Radio Output “On” Display
At the same time the sleep counter is reset to 90 minutes, and the sleep counter begins to count. The “On” display
is displayed for 1 or 2 seconds following the ON input, and then the display returns to current time display.
Example: If an ON input occurs in the interval A in figure 18, then the display returns to current time
display at point B. (Shaded section: “On” display)
Figure 18 “On” Display Timing
The operations performed on an ON input are as follows:
— Any alarm operation in progress is stopped.
— The RADIO OUTPUT pin output is set to the low level (high impedance).
— The LED display is restored to current time display.
— The sleep counter is reset to 90 minutes, and the count operation is stopped.
