Setting the Current Time
“0:00” flashes in the display when installing the batteries for the first time
or when the unit has been reset. Set the clock to the current time.
This unit can display local time, which is the time for your time zone, as
well as world time, which is the time for any other area in the world.
For the calculation of the time in other areas of the world, the time
difference* between the local time and the UTC (Universal Time
Coordinated) is used (see page 14, “Time difference with UTC for each
area”). To find out the correct time, set the correct time and time
difference of the area you are in.
* This unit uses time zones to pinpoint specific areas.
1
If the radio is turned on, press POWER ON/OFF to
turn it off.
Note
You cannot set the clock when the radio is turned on.
2
Hold down LOCAL TIME SET and press K – or + k
to choose the time difference between your local time
and the UTC.
TIME ZONE indicator will appear. Each time you press K – or
+ k, the time difference (UTC + or –) and
the “hour” of the clock will increase or
decrease accordingly.
Two short beeps will be heard when
adjusting the time difference to 
±0.
When you release LOCAL TIME SET, the
TIME ZONE indicator will disappear and the time difference with
UTC will be determined.

To set the daylight saving time, press DST to display
the 
 indicator.
If daylight saving time is not used in your area, daylight saving
time is not currently in effect, or 
 is already displayed, proceed
to Step 4.
4
Hold down LOCAL TIME SET and press –?K or k?+
to set the local time.
Each time you press –?K or k?+, the current time will decrease or
increase by a minute. To change the digits rapidly, hold down –?K
or k?+.
Two short beeps will be heard when adjusting the time to “0:00”.
5
Release LOCAL TIME SET.
“ : ” starts flashing and the clock starts
running.
To switch to clock display while the radio is turned on
Press EXE. The display returns to the previous condition
automatically after about 10 seconds or when EXE is pressed
again. The time display period is extended when the WORLD
TIME button is pressed during clock display, or when K – or
+ k is pressed during world time display. During clock display,
radio operations such as changing frequencies are not possible.
The clock will not be displayed during auto scan (page 20) or
memory scan (page 24).
For areas adopting the daylight saving time (summer time)
Press DST to display the 
 indicator if you are now in the
summer time period. When the summer time period has ended,
press DST to clear the 
 indicator. The time display will be
adjusted automatically.
Tips
• The clock is displayed in the 24 hour system.
• Press LOCAL TIME SET to stop the flashing of “0:00”.
• To adjust the time to the second, release LOCAL TIME SET at the time
of the tone.
