Dear Customer,

By purchasing this radio-controlled wristwatch, you have become the owner of a timepiece equipped with the very latest technology. It is operated simply with a corrector and a pushbutton. The additional 'manual start' function allows you to change the battery even when you are outside the transmitter range. Please keep these instructions in a safe place for ready reference.

General information

In addition to the hour and minute hands, your watch displays the seconds digitally on the left-hand side of the LCD. Steady display of the radio tower symbol indicates that your watch is showing the exact radio-controlled time. The number to the right of the radio tower is the 'reception indicator'. It shows how many days have elapsed since your watch last had contact with the DCF transmitter. Therefore, a 'O' means ideal reception conditions.

Changing the LCD display

If you press the pushbutton (right-hand button) briefly (< 3 seconds), the display changes from seconds to date (day 1 month). When you press the pushbutton a second time, the display returns to the seconds with radio tower symbol and reception indicator.

Time zone selection

Press the corrector (left-hand recessed button) briefly (< 3 seconds) with a pointed object. The number on the LCD now shows the hour. Each subsequent brief press on the corrector increases the hour by one, i.e. one time zone further east. At the same time, the hands also move forward by one hour. As from the 11th. time you press the corrector, you start returning towards the current Central European Time from a westerly direction (apparently backwards) in hourly steps. In the extreme case of Great Britain, which is one hour behind the DCF time, you must press the corrector 23 times. If you press it slowly, the hands will adjust themselves in unison. But if you press the corrector in very rapid succession, the hands may only move 11 hours instead of 23. This does not mean that your watch is malfunctioning.

9 seconds after you last press the corrector, the LCD returns to the normal display of seconds and date (adjusted to the new time zone). Instead of waiting for 9 seconds, you can also finish the time zone selection immediately by briefly pressing the pushbutton (on the right).

Returning to DCF time (after a change of time zone)

Press the corrector (on the left) for longer than 3 seconds. Your watch then automatically sets itself to all the transmitted DCF time information. Thanks to the internal time memory, this is also possible at any time when travelling abroad, even outside the transmitter range.

Note:  The manual transmitter call (refer to next section) and automatic reception (radio tower symbol and reception indicator both flash) are not possible if you have set a time zone beyond the DCF time + 1 - one hour. This limitation saves the battery.

 

Transmitter call

Press the pushbutton (on the right) for longer than 3 seconds. The seconds display jumps to '00'. The hands move at high speed to the 12:00 position and normally remain exactly there. If they do not reach this precise position, please follow the instructions given below under 'Positioning the hands'. If the hands immediately reach the exact 12:00 position, keep your watch still (preferably lay it on a non-metallic surface) to ensure reliable reception. The radio-tower symbol and reception indicator both flash and the seconds display begins to count. After a few minutes, your watch automatically sets all the current time information and the transmitter call is then complete. You can interrupt the transmitter call prematurely by briefly pressing the pushbutton (on the right). The time stored in the watch's memory is then displayed.

Positioning the hands

The hands have not reached the exact 12:00 position. Now press the corrector (left-hand side). The LCD displays 'Po O' (zero position of the hands). This message means that you must continue pressing the corrector (left-hand side) until the hands are exactly in the 12:00 position. When doing so, a brief press moves the hands in small individual steps, and continuous pressure makes the hands move at high speed. Once the correct position is reached, you must finish the positioning process by briefly pressing the pusbutton (right-hand side). Everything else takes place automatically, as if the hands had moved immediately to the exact 12:00 position, as described in the section 'Transmitter call'.

Operator error message

If, by accident, you press both the corrector and pushbutton simultaneously for longer than 3 seconds, the microprocessor stats a hardware reset. All previous time information is then lost. In this case, follow the instructions below for a New start after a Change of battery.

Changing the battery

Carefully remove the snap-fit battery cover on the back of the watch-case, using the recess provided and, if necessary, a blunt object to apply leverage. Only use the specified lithium battery type CR 1220 / 3 V and make sure that the battery is inserted with the correct polarity i.e. battery code facing out. Also take care to refit the cover correctly before pressing it in, to ensure that it remains watertight.

 

 

New start after a change of battery

The LCD displays 'Po 0'. You must move the hands to the exact 12:00 position

with the corrector (left-hand side) and conclude this operation with the pushbutton (right-hand side), as described in the section 'Positioning the hands'. Then, if the reception conditions are good the watch sets itself automatically, as described in the section 'Transmitter call'. After your watch has received the transmitter signal for a few minutes, it displays the correct time and date. If reception conditions are bad, or your location is outside of any transmitter range, your watch will not be able to receive the transmitter signal completely and no time information will be displayed. In this case, the special software enables you to carry out a manual start following the instructions in the next section.

Manual start

After positioning the hands, as described above, press the corrector (left-hand side) briefly. The minutes are displayed on the LCD. If you continue to press the corrector (left-hand side), the LCD minutes and the hands will be adjusted (brief

press = step-by-step adjustment; continuous pressure = high-speed adjustment). In this way, you can synchronise your watch with another clock or watch, pressing the corrector for the last time exactly on the minute.

Finish the manual start by briefly pressing the push-button (right-hand side). A steady '1' is displayed next to the LCD seconds to indicate the manual start. The radio tower symbol is not visible. In manual start mode your watch attempts to receive the transmitter signal every hour on the hour. The transmitter call is also possible, but should only be carried out when you are within the transmitter range. After successful reception, your watch automatically displays the radio-controlled time (radio tower symbol is visible).

Automatic functions of your watch

During the night your watch's receiver is switched on at 2, 3, 4, 5, and 6 a. m. the internal time memory is synchronised by radio signal accurate to the second. At these switch-on times the radio tower symbol flashes. It all five automatic attempts to receive the radio signal fail to produce exact synchronisation, the number in the reception indicator moves up by '1'. Days on which there is no reception are added together. On such days, your watch still operates very accurately on the quartz time base thanks to the internal time memory. The next time that a successful reception makes synchronisation possible, the reception indicator is reset to '0'.

Changeover from Summertime to Wintertime (and vice-versa)

If reception conditions are good, your watch changes from summer to winter time,

at 2 a. m. or 3 a. m. If interference prevents reception, the changeover may be delayed until later in the morning.

If the second display or date display flashes, this indicates that the battery voltage has dropped below 2.4 V. All watch functions still operate normally, but you should have a new battery fitted within the next few weeks.
