1. Radio technology

Cutting edge chronography.

5,000 years have now passed since the advent of chronography. Starting with

sundials and water clocks, advancing to mechanical clocks in the 13th century

and then followed by quartz watches, chronography has now culminated in

the radio-controlled watches by Junghans.

Radio-controlled watches by Junghans are always accurate and never require

adjustment if reception conditions are adequate. Junghans radio-controlled

watches are perfectly accurate because they are linked to the most accurate

clocks in the world by radio signals.

In Europe, this is the caesium clock of the German National Metrology

Institute (Physikalisch-Technischen Bundesanstalt, PTB) in Braunschweig.

In North America, this is the caesium clock of the U.S. Department of

Commerce, the National Institute of Standards and Technology (NIST) in

Boulder, Colorado.

In Japan this is the caesium clock of the National Institute for Information

and Communication Technology, an association of the government office.

Your Junghans Mega 1000 radio-controlled watch is able to automatically

receive the radio signals of the following time signal transmitter stations:

– DCF77 in Mainflingen (24km south-east of Frankfurt am Main) for Europe,

– WWVB in Fort Collins, Colorado (USA) for North America

– JJY40 on Mount Ohtakadoya (near Tokyo in north-east Japan) for Japan

– JJY60 on Mount Hagane (in south-west Japan) for Japan,

the East coast of China (Shanghai),

for South Korea and parts of Taiwan.

4342

This means that within range of one of these 4 transmitter stations your

Junghans Mega 1000 will display the exact time when reception conditions

are adequate.

Junghans radio-controlled wristwatches automatically synchronise themsel-

ves every day with the DCF77,WWVB, JJY40 and JJY60 time signal transmitters.

If your Junghans Mega 1000 radio-controlled watch is unable to receive a sig-

nal due to interference (e.g. thunder storms, electronic devices, lighting dim-

mer switches) it will automatically attempt to receive a signal the following

day at the same time.

The time can also be synchronised manually by calling a transmitter e.g. from

a place with better reception.

The most recent time information received is stored in an internal time memo-

ry. This time is then kept by a high-precision 32 kHz quartz oscillator until the

next time your watch is synchronised.

The radio-controlled time synchronisation function of your Junghans Mega

1000 radio-controlled watch not only ensures total time accuracy, but also

automatically switches (at night) from winter time to daylight saving time

(Europe and North America) and vice-versa when reception is available.

The Junghans Mega 1000 time zone adjustment function enables you to set

your watch to the relevant local time when travelling in countries in other time

zones.

2. Operational requirements

Make sure that the battery has enough power to ensure the continuous

operation of your watch.

The watch regularly checks whether sufficient battery power is available. If the

battery is low on power (empty battery or low ambient temperature affecting

battery performance) then a battery indicator appears in the LCD display. If the

battery does not recover (e.g. due to higher ambient temperature) you should

bring the watch to your specialist retailer or send it to the Junghans Service

Center within a few weeks to have the battery replaced.

Battery type: CR 1620 – average service life: approx. 2 years

Please ensure that the battery is disposed of appropriately and in accordance

with the legal regulations.

3. Automatic time synchronisation

The fully automatic time synchronisation takes place daily using the DCF77

(Europe) transmitter with CET (Central European Time) at both 2:00 und 3:00

hours, as well as CEST (Central European Summer Time) at 3:00 und 4:00

hours depending on the current local time.With the transmitter WWVB (North

America) and JJY40 respectively JJY60 (Japan) at 2:00 and at 3:00 hours

depending on the current local time.

The display switches itself off automatically when the automatic synchronisa-

tion commences.The display will remain switched off for the whole of the syn-

chronisation period (maximum 9 minutes) or until the procedure is manually

discontinued. The automatic time synchronisation procedure can be disconti-

nued with the use of the T1 button.With the use of one of the buttons ranging

fromT2 toT5, it is possible to display the current time during the synchronising

procedure by keeping the button depressed or, by pressing the T5 lighting but-

ton which will display the time for the duration of the illumination.Hereby, the

current hour, minutes and seconds as well as weekday, day, month and year will

be displayed.

T1T4

The date is also automatically adjusted by the time signal, and this function

also takes 29 February into consideration during leap years.

If, within a 24-hour period, all attempts to receive a signal fail to correctly syn-

chronise the watch, the reception indicator increases by 1 point (see chapter 6,

”Description of the reception indicator mode”). The indicator increases by 1

point for every further day that a signal is not successfully received. On days

when the watch has not been synchronised time is kept with the accuracy of

a quartz watch using the internal time memory. The watch will be synchroni-

sed as soon as a signal is successfully received.

Recommendation: The best conditions for reception of the time signal at night

exist when the watch is not being worn and is not placed near to electronic

devices, mobile telephones or cordless telephones.

4. Functions

The Junghans Mega 1000 has a variety of functions that are shown in the

display. The watch is operated using the five buttons above and below the

display as well as on the side of the watch (the button designations are shown

in the overview located in the foldout front cover).

4.1. Time display modes

The following five time display modes are available.

In these modes the watch cannot be adjusted using the T1 or T2 buttons. Only

T3 (to switch between Time, Stopwatch, Countdown Timer and Alarm modes)

and T4 (to select time display mode) are active so that the watch settings can-

not be accidentally changed.

if this is not the case, press T3 until one of the time display modes is shown.

Press T4 until the reception indicator is shown (time display mode 5: time,

transmitter indicator and reception indicator).

If the reception indicator reads 0 then the watch was properly synchronised

during the previous night.The numbers 1-9 show the number of days in which

watch has not been automatically synchronised due to poor reception. The

indicator returns to 0 the next time the signal is successfully received.

7. Manuel Synchronisation (Calling the transmitter)

In the various time display modes, it is possible to

carry out a manual synchronisation or so called

transmitter call.

For this purpose press the T1 button for a period lon-

ger than 3 seconds. The display switches itself off
