2. Remove batteries.​

  • Note that the proper and safe method for removing, inserting and replacing the batteries is described in the product guide/instructions.
  • Exhausted batteries are to be removed from the appliance and safely disposed.​
  • Separate batteries from other types of waste and recycle them via your local collection facility.​

3. Install new batteries.​​

CAUTION

  • Non-rechargeable batteries must NOT be recharged. DO NOT recharge Lithium or Alkaline primary cells (disposable) as they are not designed to be recharged.​
  • In case of battery leakage, replace all the batteries.​
  • Different types of batteries, or new and used batteries, are not to be mixed.​​
  • If the device is to be stored unused for a long period, the batteries should be removed.​
  • The battery connectors should not be modified; this eliminates the possibility of a short circuit.​
