Last Fix Repeat ("Lfr") - di-GPS Mini 3L Series User Manual

GPS data are only recorded when GPS icon displayed on the top of LCD panel of DSLR
camera. Please make sure that GPS icon is displayed before shooting.

Last Fix Repeat ("LFR")

di-GPS® Mini 3L series GPS receiver continuously reports the last fix when the GPS
signal is lost or the unit is out of the GPS coverage. With this new function, di-GPS®
Mini 3L series GPS receiver is able to provide the last fixed GPS data with current UTC
date/time to the DSLR camera even if there is no GPS signal, for example inside
buildings.
During initialization, di-GPS® Mini 3L series GPS receiver needs to obtain a first fix
before the LFR works properly. Once the GPS unit has a good position fix, the GPS will
continuously report the last fix with current UTC date/time if the GPS signal is lost or the
unit is out of GPS coverage. Once the new fix available, the GPS unit will immediately
report the updated GPS position to the camera.
After a power reset (power off....on), di-GPS® Mini 3L series GPS receiver reads the
last GPS position in internal memory. If there is no GPS data in the internal memory or
the internal clock is out of battery, di-GPS® Mini 3L series receiver will report no fix
available. The camera's GPS icon will flash and no GPS data will be recorded. The
GPS unit will report the last recorded GPS data in the internal memory with current UTC
date/time after power reset. The internal Real Time Clock (RTC) is powered by the built-
in super capacitor. The operation time of built-in super capacitor is about 4 hours at
room temperature after the GPS unit turned off. Exhaustion of power of super capacitor
may cause incorrect RTC. Turn on the GPS unit and the super capacitor will be
charged in a few minutes. The last good fix will be recorded in each photo until a new
fix available.
Some models of the DSLR camera (Nikon D7000, D700, D3, D3S & D3X....) support
the function "Use GPS to set camera clock". To prevent the incorrect time set, disable
the "Use GPS to set camera clock" function under the GPS menu or turn on the GPS
unit and wait for new fix before turn on the camera.
