Техническая Спецификация для Eurochron EFAUS 100 - Radio Controlled Solar-powered Watch EFAUS 100

The radio wrist  is use to receive DCF, MSF, WWWVB and JJY (60kHz) radio signals. 
The time is displayed analogue. Furthermore, on the integrated LC display the day of 
the week (in German or English), the date, the seconds and the charging condition of 
the accumulator are displayed.  A nonvisible solar cell is integrated to recharge the 
accumulator (type ML 2016). In case there is no radio siognal available the watch can 
be set manually. For this 31 cities can be selected from different time zones.

This product complies with the applicable National and European regulations. All

   Operating Instructions

   Please read all the instructions before using this device, they include 

 

   For safety and approval (CE) reasons, unauthorised conversions and/or modifi -

cations to the product are not permitted. 

 

   Do not allow children to play with the device. The product contains small 

parts that can be swallowed, and a battery.

 

   Do not carelessly leave the packaging material lying around since it could 

become a dangerous plaything for children.

 

   This product must not be exposed to high mechanical pressure.

 

   Do not expose the product to extreme temperatures, strong vibrations or 

strong mechanical stress.

 

   Handle the product with care. Shocks, hits or a falls even from low heights 

can lead to damages.

   Batteries/rechargeable batteries do not belong in the hands of children.

   Do not leave the batteries/rechargeable batteries lying around in the open; there 

is a risk of them being swallowed by children or pets. If swallowed, consult a doc-
tor immediately.

   Leaking or damaged batteries/rechargeable batteries might cause acid burns 

when making contact with skin. Therefore, in such a case use suitable protective 
gloves.

   Batteries/rechargeable batteries must not be short-circuited, opened or thrown 

into a fi re. There is a risk of explosion!

   Do not recharge normal, non-rechargeable batteries, risk of explosion! There is 

a risk of explosion! Only charge rechargeable batteries that are intended for this 
purpose; use suitable rechargeable battery chargers.

   Check that the polarity is correct, when inserting the batteries/rechargeable bat-

teries (pay attention to plus/+ and minus/-).

Attempts to receive the DCF signal for daily automatic synchronisation are being 
made at 2 a.m. and 3 a.m.  One successful reception per day is suffi cient to keep the 
deviation to less then 1 second. 

The DCF signal is encoded and transmitted via a DCF transmitter in Mainfl ingen 
(near Frankfurt). Its range is up to 1,500 km and, under ideal reception conditions, 
even up to 2,000 km. 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 receive four different radio signals: DCF, MSF, WWVB and JJY 
(60kHz). By receiving one of these signals the time of day and the date are set 
automatically. The time of the day must be set manually within the respective range 
of the transmitter. Manually setting of the summer and winter time of course is no 
longer necessary. 

Reception of the respective radio signal depends on the location and the position, 
and on disturbing signals as well that, for example, may originate from computers, 
television sets and micro waves. Withing rooms made of steel concrete the radio 
signal is alse weakened.

If your watch does not display the correct time after delivery, the DCF receiver has 
to be triggered manually. For this observe chapter "Manual setting of the time".

   Due to storage and transport the accumulator might be discharged. You can 

recognise this if all hands are set to 12 o'clock or if the seconds hand is only 
moving every two seconds and skipping one second. In every case, recharge 
the accumulator before the watch is started. For this please refer to the chap-
ter "Recharging of the accumulators".

- Impressed 1x: Shows, if a radio signal is received. 

-  Impressed 1x: Shows the charging condition of the ac-

cumulator

-  Press and hold for about 3 seconds: Search for the radio 

signal

- Impressed 1x: Indication of the weekday

- Impressed 1x: Display of the date

- Impressed 3x: Indication of the seconds

-  Impressed 4x: Shows the charging condition of the ac-

cumulator

- Press and hold for about 3 seconds: Main Menu

   Hold button 1 for about 3 seconds until the antenna symbol fl ashes in the display.

   If possible, place the watch in the vincinity of a windos for a possibly optimal 

receptiom. Have the watch either pointing upwards or downwards. Do not tilt the 
watch to the side.

   During the search the strength of the signal is shown. This helps when searching 

for a suitable location for the reception of the radio signal.

   The watch now searches for the radio signal. This process can take several min-

utes.

   After completion of the radio signal search and after the quick run of the minutes 

hand the watch shows the normal time of day again.

   In order to check if the radio signal search was successful, now press button 1.

Successful reception:  On the display "OK" is shown besides the antenna symbol.

No reception: 

On the display "NO" is shown besides the antenna symbol.

If the watch does not receive an signal place the watch at another location. If neces-
sary, leave the watch lying in the vicinity of a window during the night, since the re-
ception is better by night than by day. If this is not the case the watch is not located 
within the range of the radio signal transmitter. If so, set the watch manually. This is 
described in the chapter "Manual setting of the time".

The days of the week can be shown either German or English. For this purpose, 
proceed as follows:

   When in normal time mode, keep button 2 impressed for about 3 seconds until a 

3-digit city codes appears on the display.

   Press button 2 again. On the display the day of the week is fl ashing, e.g. TUE 

(=Tuesday).

   Press button 1 to change the language.

   Press button 2 in order to confi rm the selection. The confi rmation process takes 

a few seconds. During that "WAIT" appears on the display.
