INTRODUCTION

Congratulations on your purchase of Jumbo Display Millen­nium RF Countdown Clock (JM828CD).

The JM828CD is unique in that it has a long-range countdown
timer function. Ideal for the coming millennium, this device is
also an ideal reminder for any future date of importance. Special
dates such as graduations, birthdays or special events, can be set
and the alarm will activate on that day.

In addition the JM828CD is a clock calendar with two daily alarm
functions. A radio frequency (RF) controlled timepiece, JM828CD
can maintain superbly accurate time. It features a jumbo-size,
2-line, liquid crystal display (LCD) and has a bar graph that
shows the amount of time left to a set target date.

ABOUT RADIO RECEPTION

The JM828CD is designed to automatically synchronize its cal­endar clock once it is brought within range of the Frankfurt
DCF77 radio signal [UK version, Rugby (radio signal MSF)].

When the JM828CD is within range, the radio-control mecha­nism will override all manual settings.

Upon receiving a radio signal, the Radio Reception Icon will start
to blink. Generally, complete reception take 2 to 10 minutes
depending on the strength of the radio signal.

When the reception is complete, the Radio Reception Icon will
stop blinking.

For better reception, place the clock away from metal objects and
electrical appliances to minimize interference.

Alarm 2 display

Note: The UK version will feature a 12-hour A.M. / P. M.
time display format.
