WEATHER FORECAST RF WALL CLOCK
INTRODUCTION
Congratulations for purchase of the Weather Forecast RF Wall
Clock with Remote Thermometer (JMR838WFA).
The JMR838WFA is designed to receive RF signals generated by
the US Atomic Clock, one of the world's most accurate timekeepers.
Each time the JMR838WFA receives this signal, the current time
and date is synchronized with the US Atomic Clock.
the JMR838WFA also displays outdoor and indoor temperature
and uses barometric information to indicate weather forecasts
and atmospheric pressure trends.
Included in this package is a remote thermo-sensor. Place the
thermo-sensor in a sheltered outdoor location within a 30 meters
(100 feet) radius of the main unit and it will transmit outdoor
temperature readings to the JMR838WFA.
Other features include a daily crescendo alarm with an eight-
minute snooze function and an extra-large LCD display.
