SenseCam v2.3 User Guide Page 20 of 31 10/03/2009
If for some reason the camera appears to have stopped working at any time, as a last resort it
may be necessary to switch the power off completely as described above, wait ten seconds,
and then power it back on again. Ideally, the slide switch should only be used after the
camera has been put into the „off‟ mode with the power button, to make sure that all files are
flushed to memory cleanly.
4.10. Slow start-up
The SenseCam can sometimes be slow to boot up when switched on. One reason for this is
the time required to reopen a very large SENSOR.CSV file in order to append to it – this
requires traversal of a large number of cluster chains. The best way to mitigate this is to
synchronise the SenseCam with the PC reasonably frequently, thereby moving all the files
(including the SENSOR.CSV file) off the device. If this is not possible, the only alternative
is to wait (perhaps many minutes).
