Europe, U.K., Australia, China and Singapore models
use a 24-hour display. U.S.A. and Canada models use a
12-hour display shown by “AM (PM) 12:00”. For General
model, either the 24-hour display or the 12-hour display
is selected depending on the setting of the FREQUENCY
STEP switch on the rear panel, so you cannot select a
desired type freely.
In the event of a power failure or when the AC supply
lead is disconnected.
The time display will go out, however, the clock will function
for about 5 minutes without power supply. So you do not
have to reset the time if the AC power supply is resumed
within about 5 minutes.
When the AC power supply is resumed after more than 5
minutes pass without power supply, the time display will flash
on and off to indicate that the time must be reset.
