Sima wx-268 Benutzerhandbuch

The WX-268 continuously monitors the broadcast of the atomic clock signal on

WWVB from the NIST laboratories in Colorado. NIST continuously broadcasts the time
signal on WWVB (60 KHz) which can be received anywhere in the continental United
States where long range AM radio reception is possible.

Due to the nature of the earth’s atmosphere, your location and seasonal weather

conditions, daytime reception can be limited. The radio will search for the NIST signal
every night when reception is optimal. Upon receiving the signal the clock will
automatically be adjusted to the correct time. In addition, the clock will automatically
make adjustments for daylight savings time unless you select OFF in the DAY SAVING
time menu when programming the radio. See page 12,
SETTING THE CLOCK/CALENDAR.

An icon indicating the status of the NIST clock

appears directly to the right of the time display on the
LCD screen, as shown at right. The status of the NIST
clock is indicated by the icon as follows:

Steady - NIST signal received and time set in past 24 hrs.
Blinking - Receiving NIST signal and resetting time.
No icon -  The unit has not received the NIST signal or set the clock in the past 24 hrs.

Note: The NIST antenna is located inside the radio.  If your radio is being used on a desk
or table top, try rotating it 90 degrees to improve reception. If your is mounted to the wall,
try mounting it on a wall perpendicular to the one it is currently on (e.g. if it is on a north-
south wall try an east-west wall).
