RADIO SIGNAL RECEPITION
About Radio Signal Reception
The Model 1500E is programmed to see the WWVB radio signal everyday. Initially
the time recorder will search for a signal immediately after you set the time zone.
Once the clock has initially set, it will search for the signal 9 times per day to
maintain accuracy. The WWVB signal is the strongest early in the morning, when
there is the least amount of interference from other sources.
There are some environments and weather conditions that may influence the
reception of the AM radio signal. Just as with an AM radio, the Model 1500E can
be positioned for optimal reception. For instance, it is best to position the clock
away from metal studs and toward the direction of the tower in Colorado. Since
this time recorder contains a highly accurate quartz timer, it will function with a
very high level of accuracy between signal receptions. The Model 1500E will
operate as normal electronic time recorder without having to receive the signal.
Since it is also operates as a highly accurate (+/- 15 seconds per month) quartz
time clock, it will function properly while outside the reception area or if it can not
receive the WWVB signal.
Verifying the Time
The best way to verify the correct time is to call the NIST at (303) 499-7111 (long
distance charges may apply). Any other sources, including the time number in
your local phone book, the Internet, cell phones, and Cable TV receivers may be
off by several seconds.
Signal Reception Indicator
FLASHING: Unit is receiving the atomic radio signal.
ON: Unit successfully received the atomic radio signal.
OFF: Unit was unable to receive the radio signal.
