Other keys
DISPLAY
When HOLD is HIGH and the clock is enabled (DIMRX
CLOCK =1), use DISPLAY to change what is displayed.
Each time DISPLAY is pressed, the display toggles
between the frequency display and clock displays as
shown in the following figure.
SLEEP
SLEEP is used to set the sleep time. If SLEEP is pressed
while ‘SLEEP’ is not displayed, ‘SLEEP’ and ‘90’ appear
on the display. Each time SLEEP is pressed while the
sleep time is displayed, the sleep time decreases by 10
minutes. Five seconds after setting the sleep time, the
previous display is restored. If the sleep time is set to 0,
the ‘SLEEP’ display disappears and the sleep mode
setting is canceled.
If the sleep time has already been set, SLEEP can be
pressed to check the remaining sleep time even while the
frequency or clock is displayed. After 5 s, the previous
display is restored.
When in sleep mode, TIMER OUT is HIGH.
TEST
When TEST is pressed and HOLD makes a LOW-to-
HIGH transition, all segments of the LCD turn ON. If
TEST is pressed again, the clock display turns ON,
assuming there is a clock, and starts counting at a rate of
1 min/s. If there is no clock, pressing TEST a second
time cancels the test.
