Question: I replaced the batteries, however soon after I installed the new set the unit displayed "Low Bat." again?
Answer: Please remove the battery cover and wait at least 2 minutes before reinstalling the cover again. When the battery cover is removed the batteries are disconnected. When installing a new set of batteries too quickly the microprocessor may sometimes enter a wrong mode and thus display wrong information. Do also refrain from pressing any buttons for about 15 minutes after installing new batteries.
