Although reception of Germany's "DCF77" signal is good in the middle of Europe, there
are difficulties outside of its German-speaking regions, and in the rest of the world the
signal is not available at all. In contrast, GPS (Global Positioning System), which is
operated by the USA via satellite signals, can be used anywhere on the planet.
Note: Of the extensive GPS data involved here, the Zeitgeist 2 only uses information
relating to the time of day, i.e. it cannot be used to determine your geographic location.
All radio-based systems need good reception of radio sources without any interference
or obstructions, preferably outside without metal parts in the vicinity. Time
synchronization is generally also possible if the device is placed on a suitably positioned
windowsill.
As the GPS module consumes a relatively high level of power, the Zeitgeist 2 will try to
perform satellite measurement only for around half an hour. If this fails, it will be aborted
with a message to this effect. Try again in a more suitable location.
With good reception time synchronization is normally complete within one or two
minutes.
You can start the function either with the Settings menu or via quick access in the home
screen using the button combination
Top+Middle LONG
.
Following the prompt, you then change "GPS time" from "Disabled" to "Enabled". The
Zeitgeist 2 will then confirm this acoustically, return to the home screen and show the
corresponding status icon on the display; see picture in section 2.3.
Then place the device in a suitable location and wait until there is an acoustic message
confirming the operation was successful. If this is not the case, you will hear a message
stating GPS has been cancelled after 30 minutes max. Both messages then disable
GPS reception to save battery power and remove the status icon on the display.
Note: Automatic GPS time setting does not affect setting of the time zone and daylight
saving time.
This means that if you return from vacation in another time zone, you have to set these
values manually again, for example to "Europe" and "plus 1 hour".
7.9 Bluetooth
The technology used in the Zeitgeist 2 also includes a wireless module whose features
can be employed in a number of ways, with some ready for release or others under
development by the manufacturer. The device at all events offers power-saving
Bluetooth low-energy functions.
After calling up the function in the Settings menu, you see a list currently comprising two
entries, "Time Beacon" and "Pillow / Bed Shaker".
To scroll use Top or Bottom SHORT , to select or start a setting with Middle LONG .
Middle SHORT
determines whether the relevant module is currently switched on or off.
Note: Currently under development, "Time Beacon" is in future to be used for time
synchronization on other devices via "Bluetooth Beacons".
