Conrad Wristwatch 67 14 48 - Analogue Radio-Controlled Watch Operating Instructions

Intended use

A radio clock always shows the correct time after reception of the relevant signal. The basic features of this analogue radio-controllled wristwatch are: digital time, date, seconds with weekday and time zone setting. You can set the time manually yourself, e.g. for a holiday trip, or select the time zone from EU, Japan, UK or America via an additional settings button; the corresponding time sets itself automatically then. Summer/winter time is set automatically.

Any usage other than described above is not permitted and can damage the product and lead to associated risks such as short-circuit, fire, electric shock, etc. Please read the operating instructions thoroughly and keep them for further reference.

Functional description

The radio signal (DCF) for the exact time display in Germany is encoded and transmitted by a transmitter in Mainflingen near Frankfurt. The transmitter has a range of ca. 1,500 km, under ideal conditions even up to 2,000 km. Watches with integrated radio receivers can receive and decode the radio signal within this transmission range. For these watches, manually setting the time is thus not necessary (e.g. when changing from winter to summer time). The automatic change between summer and winter time takes 24 hours, at most.

Among other things, the DCF signal includes the precise time (theoretical deviation of 1 second in a million years!) and the date.

This watch can likewise receive time signals in other countries. Along with Germany's DCF77 signal, the watch can receive Great Britain's MSF signal, Switzerland's HGB signal, WWVB signals in the USA and Japan's JJY signal.

Start-up operation

1. The basic setting of the LC display is the display of hours and minutes.
2. Pressing the button A once switches to the display of month and date.
3. Pressing it twice switches to the display of seconds and weekday.
4. Pressing it a third time displays the time zone.
5. Pressing it a fourth time puts the display back into the basic setting.

Automatic reception of a time signal

Every day, the watch attempts to receive the currently set time signal up to three times if previous attempts fail. Compare the table below. (*UTC Coordinated Universal Time is the reference time.) UTC corresponds to GMT.

CET corresponds to UTC + 1 h

Manual reception

1. Press button A for at least 2 seconds to start a reception attempt. The - symbol starts flashing. The signal strength display shows the quality of the signal received.
2. If a reception attempt fails, the time previously set on the watch is resumed. No further display symbol is displayed.
3. Pressing button A for at least 2 seconds stops the reception attempt.

During a reception attempt, the hands of the watch continue to move.

Manual time setting

1. Press button B until the time zone setting flashes.
2. Press button A to set the time zone. Set the time signal required at your geographic location ("number + h" = difference to UTC, "EU" = Germany, "US-P + US-M + US-C + US-E" = time zones in the USA, "UK" = Great Britain, "CH" = Switzerland).
3. Confirm the input by pressing on button B. The summer time setting flashes.
4. Press button A to set or turn off summer time. The appearance of "ON" and the - symbol indicate that summer time is activated. ("OFF" = off, "AUTO" = automatic)

17. Confirm the input by pressing button B. The time display appears again. The hands of the watch turn quickly until digital time display and analogue time agree once more.

During manual time setting the minute hand stops.

The watch leaves the setting mode automatically if no setting is activated for more than a minute.

Zero setting mode

1. Pull the crown (C) out. All hands stop and the LC display indicates "00:00."
2. Put the hour and minute hands in the twelve o'clock position.
3. Push the crown (C) back in.
4. Put the second hand in the twelve o'clock position by pressing button A briefly each time until the hand reaches its goal in second-steps.
5. Press button B to activate an attempt to receive the time signal. The - symbol starts flashing.
6. Press button A for 2 seconds to leave the zero setting mode. The time that was previously set appears again.
7. If after one minute no button is pressed, automatic time reception is activated.
8. If a signal is successfully received, the hands turn until the times are synchronised.

Care and maintenance

The watch water- and shock-resistant for normal use. But striking it against hard surfaces should be avoided, as should excessive contact with water. The enclosure is to be wiped off with a soft dry cloth, as needed. If there is more dirt, please use a lightly moistened cloth. Do not use any abrasive cleaners or solvents.
