RADIO CONTROLLED CLOCK
WITH TEMPERATURE AND HUMIDITY
Model: C8461A
USER MANUAL
Thank you for purchasing this delicate radio clock with temperature and
humidity. Utmost care has gone into the design and manufacture of the clock.
This manual is used for WWVB version. Please read the instructions carefully
according to the version you purchased and keep the manual well for future
reference.
PRODUCT OVERVIEW
C
LOCK
DISPLAY
GETTING STARTED
●
Remove the battery door.
●
Insert 4 new AA size batteries according to the
“+/-”
polarity mark on the
battery compartment.
●
Replace the battery door.
●
Once the batteries are inserted, full segment of the LCD will be shown before
entering the radio controlled time reception mode.
●
The RC clock will automatically start scanning for the radio controlled time
signal in 8 seconds.
NOTE:
If no display appears on the LCD after inserting the batteries, press the
[ RESET ]
button
by using a metal wire. In some cases, you may not receive the signal immediately. Due to
the atmospheric disturbance, the best reception often occurs during nighttime.
DAYLIGHT SAVING TIME (DST)
The clock will automatically advance the time by one hour in the spring and back
an hour in the fall, provided that the DST function is not turned off.
DST function is set to AUTO by default.
RECEPTION OF RADIO CONTROLLED SIGNAL
This RC clock includes a built-in receiver which picks up the signal from the
WWVB station. Therefore, the clock automatically sets the time, date and
weekday.
●
The clock automatically carries out four periodic synchronization procedures
(at 2:00 AM, 8:00 AM, 2:00 PM and 8:00 PM daily) with the RC signal to
correct any deviations to the exact time.
●
Once the unit synchronizes successfully to the RC signal, the signal icon
“ ”
will show up. Each synchronization process will take between 6 to 16
minutes.
●
To manually start or stop the RC signal reception, press
[ RCC ]
button.
NOTE:
●
The strength of radio-controlled time signal from the transmitter tower may be affected
by geographical location or building around.
●
Always place the unit away from interfering sources such as TV set, computer, etc.
●
Avoid placing the unit on or next to metal plates.
●
Closed areas such as airport, basement, tower block, or factory are not recommended.
SIGNAL RECEPTION INDACATOR
The signal indicator displays signal strength in 4 levels. Wave segment flashing
means time signals are being received. The signal quality could be classified
into 4 types:
TIME ZONE SETTING
