Changing the Battery
Besides the Unit's LCD display, the battery level can be
displayed on the computer screen via the software if a Unit is
connected to the computer with a USB communication cable.
If a Unit is left without a battery for some time, all data may be
lost, so please work quickly when changing the battery.
When a battery life warning signal appears, try to replace
the battery with a new one as soon as possible.
1. When it is time for the battery to be replaced, a battery life
warning signal will appear.
* If, at this time you change the battery,
recording will continue uninterrupted and
all data will be saved for downloading.
2. If the battery is not changed but it remains in use, "SLP" will
appear in the LCD display. Recording will stop in order to
protect recorded data until this point.
* If you change the battery at this point, it
is still possible to download all saved
recorded data.
3. If the battery is further left unchanged, the display will
automatically shut off and all previously recorded data will
be lost.
