About Battery Life
When battery life goes low, a battery life warning mark will be
displayed to inform you it is time to replace the battery. If battery life
goes even lower, the Unit will automatically go into sleep mode in
order to save data.
- In sleep mode, the Unit cannot be turned on or operated as usual.
- When replacing the battery, if the battery has been removed for more than five
minutes, the data stored in the Unit may be erased. It is recommended to first
download any necessary recorded data to your computer before replacing the
battery.
- Also, you will lose all data if the battery drains completely; make sure to
replace the battery as soon as possible.
