CAUTION
Once the “Low Battery Mark” starts to light, replace with new batteries immediately.
Even if the unused battery if it has been stored very long time may cause a malfunction (such as a
buzzer sounding without being displayed). If this happens, replace with a new battery.
Both batteries must be the same type, and use all new ones. Different types or mixing with old
batteries may cause rupture or leakage.
Do not dispose of the used battery in a fire.
Doing so may cause an explosion which may lead to an

regulations.
Keep batteries out of reach of children. If swallowed, contact a medical assistance immediately.
