To avoid incorrect measurements, replace the batteries when the battery
indicator is low. Use only AA alkaline batteries and follow all battery care
guidelines from the manufacturer. To remove the batteries, first ensure the
product is in OFF position, then unscrew the battery cover. When installing
the batteries, be sure that the battery polarity is correct to prevent battery
leakage. Secure the batteries by screwing the battery cover back in place
(Figure 3.2).
