WARNING
• Using batteries other than those supplied or recommended for use with the meter may significantly
reduce the life of the batteries. Batteries other than those recommended may leak and corrode
the battery contacts within the meter. Using batteries not supplied or recommended may void the
warranty.
• Replace all batteries of a set at the same time. Newly purchased batteries should not be mixed with
partially exhausted ones. Batteries of different electrochemical systems, grades, or brands should
not be mixed. Failure to observe these precautions may result in some batteries in a set being driven
beyond their normal exhaustion point and thus increase the probability of leakage.
