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.
