Reading The Led Status - Extech Instruments S3750THS User Manual

The battery terminals are well recessed inside the printer. Do not
!
allow them to contact conductive material since this may create a
short circuit which could cause injury or start a fire.
When using the wall mounted charger ensure the socket outlet is close
!
to the printer and easily accessible during the battery recharging
process. Either switch the socket off (if supplied with a socket switch)
or pull out the charger from the socket or disconnect the plug from the
printer in the event of any problems.
