Sony GPS-CS1KASP Manuel d'utilisation
On the internal memory
The unit can record GPS log files up to about 360 hours.
When the available internal memory becomes about 10 % or lower, the
MEM FULL lamp flashes red. When the internal memory becomes full,
the power is turned off automatically after the MEM FULL lamp lights
up for a minute.
If you press the CLEAR button (page 17) longer with an object with a
tapered tip while the power is turned on, all the GPS log files in the
internal memory will be erased and the power goes off automatically.
