15. Care and Maintenance
When batteries of different brand or type are used together, or new and
old batteries are used together, some batteries may be over-discharged
due to a difference of voltage or capacity. This can result in venting,
leakage, and rupture and may cause personal injury.
• Do not mix Alkaline, Lithium, standard, or rechargeable batteries.
• Always purchase the correct size and grade of battery most suitable for
the intended use.
• Always replace the whole set of batteries at one time, taking care not to
mix old and new ones, or batteries of different types.
• Clean the battery contacts and also those of the device prior to battery
installation.
• Ensure the batteries are installed correctly with regard to polarity (+ and
-).
• Remove batteries from product during periods of non-use. Battery
leakage can cause corrosion and damage to this product.
• Remove used batteries promptly.
• For recycling and disposal of batteries, and to protect the environment,
please check the internet or your local phone directory for local recycling
centers and/or follow local government regulations
