Junghans J615.84 - Setting the Time Zone; Quartz Mode

43 42
6.2 Setting the time zone
The Junghans multi-frequency radio-controlled solar watch receives
the signal of DCF77, JJY40, JJY60 and WWVB. This means that the
watch reliably displays summer and winter time in the transmission
areas (exception WWVB, see chapter 3.).
In other time zones without radio reception the local time can be set
manually by pressing button T2 in hourly steps.
By holding down the T2 button you can fast forward to set the local
time. The hands run parallel to the setting. The date is also adjusted
automatically during the setting process.
If you wish to return the time display to the original time, press button
T2 until the original time is reached again.
6.3 Quartz mode
In order to set the time manually, press both buttons for longer than
3 seconds (or until the indicator on the LC display goes out). After the
hands have reached the 12 o’clock position, press button T1. The watch
is now in quartz mode. Quartz mode is indicated by the display sho-
wing the year, e.g. [99]. Every time you press the T2 button the display
advances by one year. Holding down button T2 scrolls through the
years quickly.
Once you have entered the current year, conrm this with a brief
press of button T1. The LC display now switches to showing the month
setting [¡ ™]. This is again adjusted via the T2 button. Conrm again the
month you have set by briey pressing button T1.
Perform the following settings using the procedure described above:
– Set the date – the LC display switches to [£ ¡] (or the nal day in the
month)
– Set the hour – the LC display switches to [™£]
– Set the minutes – the LC display switches to [∞ª]
Note: to achieve a time display accurate to the second in the LC display
set the next full minute and set using button T1 on 60 seconds, using
a reference watch or clock.
After the minutes have been set and subsequently conrmed by
pressing button T1, the hands of the multi-frequency radio-controlled
solar-powered watch move to the programmed time. The LC display
shows the date. The programmed time can be corrected by holding
down button T2 for longer than 3 seconds.
Please note: The manual setting procedure must be fully completed
before the watch is ready for further operation.
In quartz mode the watch does not perform any automatic attempt
to pick up a time signal. A manual transmitter call can be made at any
time. A successful transmitter call will overwrite the time set manually
and the watch then performs automatic time synchronisation again.
