Important Notice (Must Read)
1. For battery replacement, it is a must to use a new and high quality CR2
lithium battery for replacement. Otherwise the instrument cannot
correctly estimate the battery life.
2. During replacing the battery, after the old battery is removed, the
instrument still has residual power. Wait until the residual power of the
instrument is completely exhausted, that takes about 5 seconds, and
you can see the whole LCD screen is off. Then you can install a new
battery. Otherwise the instrument will not recognize if a new battery
has been replaced. If the remaining battery power is not exhausted
and a new battery is installed, you can remove the battery again, and
wait until the LCD screen is completely off, and install the new battery
again.
3. After replacing the new battery, the first time connect the instrument to
the application software, the software will remind the user that the
battery has been replaced. Be sure to use a brand new battery.
4. After installing the battery, do not remove the battery, unless the
battery is exhausted or the remaining battery capacity is too low that
cannot complete the scheduled task.
5. The action of removing the battery and then putting the removed
battery back is equivalent to replacing the battery. The instrument will
assume that a new battery has been replaced and the battery life is
estimated with the new battery's power. In this case, the estimated
battery life is not accurate.
6. Do not replace the battery in a humid environment, because high
humidity air can enter the instrument through the battery compartment.
The moisture inside the instrument may affect the operation of the
electronics or cause rusting of the components.
