3. Press reset button to re-start the clock and it will synchronize the channels of the transmitter 
automatically.  

 
NOTE:

  

 
1. If extra transmitters are added in the future, press the reset button to re-start the clock and 
synchronize the channel. 
 
2. Building material and the receiver and transmitter affect the effective range. Try various 
locations to obtain the best result.  
 
3. Place the units away from metal objects and electrical appliances to minimize location 
interference. Position the receiver and the transmitter within the effective transmission range; less 
than 100 feet in usual circumstances.  
 

RECEPTION OF RADIO CONTROLLED TIME SIGNAL  

 
The time and date are radio-controlled. The current time and date are automatically synchronized 
with the time signal transmitted from Ft. Collins, Colorado provided the device is within about 
2,000 miles of the transmitter. When used for the first time (after inserting the batteries or pressing 
RESET), the clock starts receiving the time signals and the reception display flashes.  
 

SIGNAL STRENGTH INDICATOR  

 
The signal indicator displays signal strength in 3 levels. Wave segment flashing means time signals 
are being received. The signal quality could be classified into three types:  
 

 

 

NOTE:  

 
1 The unit will automatically search for the time signal at 2:00 a.m., 8:00 a.m., 2:00 p.m., and 8:00 
p.m. each day.  
 
2. Always place the unit away from interfering sources such as TV set, computer, etc.  
 
3. Avoid placing the unit on or next to metal plate.  
 
4. Closed area such as airport, basement, tower block or factory are not recommended.  
 
5. Do not start reception on a moving vehicle.
