|Replacing the Batteries|
Replace the 4 AA batteries when the message Low Batteries! appears. You can expect around 30 hours battery life when using Alkaline Batteries.
Obs.: Install new batteries within 3 minutes of removing the old batteries. If you leave the batteries out for more than 3 minutes, the time and date may need to be reset. Your saved test results will not be lost. The testers battery gauge is most accurate when alkaline batteries are installed.
