12.4 Replacement of batteries
When the low voltage indicator flashes, the batteries should be replaced in time. The method of
replacement is shown in below:
a) Wait for the automatic turnoff
b) Open the battery chamber (use the thumb to push down the chamber and slide it out)
c) Take off the batteries and put in the new batteries. Note the polarity of the battery.
When the instrument lies idle for a long time, take out the batteries to prevent leaking that will
corrode the battery chamber and the poles.
12.5 Strictly avoid any collision or damp environment, etc.
