The Ws738 is designed to automatically synchronize its calendar clock once
it is brought within range of 1500km of the Frankfurt DCF77 radio signal.
When the WS738 is within this range, its radio-control mechanism will
override all manual settings.
2
When receiving radio signal, the Radio Tower symbol starts
to blink. A complete reception generally takes several
minutes, depending on the strength of the radio signal.
3
When the reception is complete, the Radio Tower
symbol will stop blinking and remain solid.
4
For better reception, place the clock away from metal
objects and electrical appliances (i.e. television, computer,
monitor, etc.) to minimize interference.
