11. TIME CORRECTION WITH GNSS
By connecting the GNSS Receiver (GNS-300) with this Quartz Master Clock, the time correction is
made automatically on a regular basis. In the Normal Mode, the time correction is made every hour on
the hour. When the GNSS receiver is connected newly, or to manually receive the GNSS time signal,
show “GNSS” display in the Normal Mode, and press SET button. Checking of the connection
status of the GNSS Receiver and time correction are performed.
Show “GNSS” display in the Normal Mode.
Press SET button to start checking of the connection
status of the GNSS Receiver,
and “-” at the right of “gp” flashes alternately if the
connection is normal.
When the GNSS Receiver is not connected with the
Quartz Master Clock, or the Receiver or the connection is
faulty, “-” remains shown. In that case, reconnect the
GNSS Receiver with the Quartz Master Clock (remove the
connector and attach it securely again), and press SET
button again to check the connection status.

The display above is shown while the
GNSS signal reception is underway,
and “o” at the right of “gp” flashes
alternately. It takes about 10 minutes
to complete the reception. Pressing
MODE button discontinues the
reception and returns the clock to the
Normal Mode.
When the GNSS signal reception has failed, the display
shown at left remains displayed.
If the reception failure persists after several attempts of
manual reception, it is necessary to relocate the GNSS
Receiver to another place (an outdoor place where you
can see the whole sky is recommended). Press MODE
button to return the clock to the Normal Mode.
Time correction is completed.
Press MODE button to return the clock
to the Normal Mode.
Note:
After the GNSS signal reception has been performed following the
procedure above, be sure to return the clock to the Normal Mode. If it is left
in the Setting Mode, the regular time correction (made hourly in the case of
GNSS) will not be made.
