Battery Indicator and Battery Replacement
Low battery
When the batteries are approximately 25% left, the battery symbol will flash as soon as the device is
switched on (partly filled battery displayed). Although the device will continue to measure reliably, it’s
recommended to replace the batteries as soon as possible.
Flat battery and replacement
When the batteries are flat, the battery symbol will flash as soon as the device is switched on (flat
battery displayed). You cannot take any further measurements and must replace the batteries.
1. Open the battery compartment at the back of the device.
2. Replace the batteries – ensure correct polarity as shown by the symbols in the compartment.
3. To set date and time, follow the procedure described in «Section 2.».
■ The memory retains all values although date and time must be reset – the year number
therefore flashes automatically after the batteries are replaced.
