Solution
- Battery performance decreases at low temperatures. Warm the battery / batteries, such as by placing them in your pocket with the terminal cover on.
- If the battery terminals are dirty, battery performance will decrease. Clean the terminals with a cotton swab and re-insert the battery / batteries several times.
If the batteries are consumed quickly at normal temperatures (23 deg C), the battery life might have been exceeded. Please replace the batteries with new ones.
CAUTION
- When you warm the batteries in your pocket, please do not put them together with metal objects such as key chains. The batteries might short-circuit.
- Please do not short-circuit the plus (+) side and the minus (-) side of the batteries with metal objects such as key chains.
- When you are carrying the batteries or if they are not in use, please make sure to attach the terminal cover.
