14.0 USAGE CONSIDERATIONS
Sleep mode
Sleep mode (power-down mode) doesn’t affect the logging system. If logging
is active when going to sleep mode, logging is resumed as the module wakes
up and first valid fixes are received.
Power-down
The CT5510’s logging system can sustain sudden power losses without major
affects; however, it’s suggested to stop navigation properly prior to switching
off the power or otherwise some of the most recently logged data may be lost
and as CT5510’s logging system performs automatic recovery checks due to
the power loss, the next power-up time may be longer.
It’s also possible that CT5510’s logging system may occasionally unable
to continue the previous log (logging start modes 2 and 4) after sudden
power-losses. In such cases, the logging system creates a new log
and continues using that one as usual.
Memory full
CT5510’s logging system automatically ceases from logging shortly before
the flash memory gets totally full. It’s thus quite normal for the logging to stop
while enough flash space for several dozen more logs seems to be available.
This early stopping is implemented to prevent problems with logging settings
and book-keeping information due to the lack of available memory.
