Symptom
The current location is
not displayed on the
viewfinder even if the
GPS function is set to
ON.
The current time
displayed on the
viewfinder is different.
The location calculation
time has stopped.
Causes/remedies
The unit cannot receive radio signals due to
objects which block the signals.
— Move to a place where you can see the
horizon.
Make sure the connector of the GPS antenna
is inserted firmly.
— Insert it until it clicks.
You have set the GPS function to ON for the
first time since you purchased the unit, or you
have not used the GPS function for a while.
You replaced the backup battery.
— In this case, it takes about 15 minutes to
begin receiving radio signals from
satellites. This is not a malfunction.
The time is displayed in UTC (Universal Time
Coordinated). There is a time difference from
your local time. This is not a malfunction.
When data cannot be received from
satellites, the time is advanced using the
internal clock. In this case, a time difference
may be generated in units of seconds. If the
unit receives radio signals from satellites
again, the correct time is displayed.
The time stops when the unit cannot
calculate the current location. But, the time
starts to advance once the unit starts to
receive radio signals from satellites again.
