4. Battery information
This device is intended for use when supplied with power from a CR2 3V, Lithium battery.
The use of any other types may invalidate any approval or warranty, and may be dangerous.
Always switch the device off before removing the battery. Ensure the correct polarity is
observed when inserting batteries.
Use the battery only for its intended purpose. Never use any charger or battery that is
damaged.
Do not short-circuit the battery. Accidental short-circuiting can occur when a metallic
object such as a coin, clip, or pen causes direct connection of the positive (+) and negative (-
) terminals of the battery. This might happen, for example, when you carry a spare battery in
your pocket or purse. Short-circuiting the terminals may damage the battery or the
connecting object.
Leaving the battery in hot or cold places, such as in a closed car in summer or winter
conditions, will reduce the capacity and lifetime of the battery. Always try to keep the
battery between 15°C and 25°C (59°F and 77°F). A device with a hot or cold battery may not
work temporarily, even when the battery is fully charged. Battery performance is particularly
limited in temperatures well below freezing.
Do not dispose of batteries in a fire! Dispose of batteries according to local regulations.
Please recycle when possible. Do not dispose as household waste.
