Note: There are some environments and weather conditions that may influence the reception of the atomic
clock radio signal. Since it also operates as a highly-accurate (+/- 15 seconds per month) quartz
time clock, the 7500E will function properly while outside the reception area or if it can not receive
the WWVB signal.
