External 12V Power Port
The external power port is located on the front of the instrument, below the button pad and LCD
Display (See Figure 1 #6).
The external power port may be used to supply the LMPL20 with an external 12V power supply. The external
12V power supply can be used to power the LMPL20 without a battery pack installed, or can be used to charge
a NiMH rechargeable battery pack if inserted in the LMPL20. If a battery pack containing Alkaline non-
rechargeable batteries is inserted in the LMPL20, the 12V supply may still be used without damaging the
batteries or the LMPL20.
Using an external 12 volt DC battery source (Vehicle battery)
1. Turn the vehicle engine off.
2. Make sure to connect the red clip to positive terminal and Black clip to negative terminal.
3. Connect to External Port
Note: Always turn the LMPL20 off before removing external power cable.
MAINTENANCE AND CARE
DO NOT store LMPL20 in cold environment. Moisture can form on interior parts when warming up. This may
cause laser windows to fog and corrosion to internal circuit boards.
DO NOT use aggressive cleaning agents or solvents to clean LMPL20.
REMOVE moisture or dirt from laser windows with a soft, dry cloth.
