WARNING – The battery is not itself waterproof. Do not get the battery wet when it is removed
from the instrument. If water seeps into the battery, it may cause a fire or burns.

input must be 5 V with at least 4 A of current capability. Each battery may take
up to 2 A while charging.
Charging a battery
• Simply slide a battery into either battery slot to begin charging. The adjacent
charge indicator will illuminate yellow when charging is in progress. The
charge indicator will change to green when charging is complete.
• Charger slots are completely independent so a battery may be inserted
regardless of the state of the other battery slot.
• Charging may take 2-4 hours if the battery was normally discharged.
• Charging may take up to 5 hours with a completely drained battery which has
been stored for several months without use.
