RADIO SIGNAL RECEPTION
About Radio Signal Reception
The Model 1600E 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 12 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 1600E 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 1600E 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.
