Setting the Clock
Operation
5. The clock starts running.
It may take about 5 minutes for the time infor-
mation to be received and displayed.
6. After the clock is initially set, it will be
adjusted periodically when the tuner unit
is in STANDBY mode.
Notes on using the “ACCUCLOCK” function:
Make sure that your FM antenna has been
properly connected as explained on page 10. It is
strongly recommended that you install an outdoor
FM antenna since the FM indoor antenna may
not receive RDS broadcasts well enough to allow
ACCUCLOCK to function properly.
The clock will display the time in a 24 hour cycle. For
example, 5:30 pm will be displayed as “17:30”.
If RDS signals cannot be received, no RDS station
will be found.
Or if an RDS signal is present but the signal is
not strong enough to allow the ACCUCLOCK
to automatically set the time, “- -:- -” will lit on
the display as shown below. If this occurs, set
the clock manually. (See page 14.)
Adjust the clock manually.
You may wish to adjust the clock manually
because the time information may differ
depending on the RDS station detected. If so,
follow the manual clock adjustment procedure
described on page 14.
There may be cases in which you can listen to
radio broadcasts but cannot use the
ACCUCLOCK function.
• Once activated, ACCUCLOCK will remember the
RDS station it uses for several weeks even if the
power cord of the tuner is unplugged. If you
move outside the service area of the memorized
RDS station and find out that ACCUCLOCK is
not functioning, see “Confirming/changing the
RDS Station used by ACCUCLOCK” on page 13
to change the memorized RDS station.
The ”ACCUCLOCK“ features an automatic clock
adjusting function automatically sets the clock time
on the tuner by means of RDS broadcast signals.
The “ACCUCLOCK” feature is available only on
the European model, and only in areas where
RDS broadcasts are available.
Adjust the clock as explained in “Setting the
clock manually” on page 14 if you are using a
model U.S. and Canadian models or if you are
using the unit in the area where RDS broadcasts
are unavailable.
Setting the clock automatically
(European models only)
ACCUCLOCK starts operating as soon as the
power cord is plugged in. It then searches for an
RDS broadcasting station which regularly sends
time signals and waits to receive such time
information. The tuner should be in STANDBY
mode until the clock setting is complete.
The following steps describe how to set the clock
automatically:
1.Plug in the power cord.
“AUTO” flashes slowly on the time display.
