“lock” onto a number of satellites as soon as the
RD8200G unit is turned on.
The time required for the GPS module to lock onto the
GPS system varies depending on the length of time that
has passed since the last time the locator was used, and
on the presence of obstacles (like high buildings, trees,
etc.) that obstruct sight to the sky.
If the unit has not been used for several days the time to
first fix may take up to several minutes.
The RD8200G locator display provides a number of
icons indicating the presence of an internal and active
GPS and when this has locked to the GPS system, the
quality of the signal received or numbers of satellites
received.
The accuracy of the GPS module is affected by the
number of satellites received and best accuracy is only
reached when the signal quality is at its maximum.

The LCD GPS operation icons provide visual information
about the status of the internal GPS module:
