To prevent thepossibility of personal injury or product damage caused bybattery exposure to extreme heat, store the device out of directsunlight.Do not use a sharp object to remove batteries.CAUTIONContact your local waste disposal department to properlyrecycle the batteries.Long-Term StorageNOTICEThe normal long-term decrease in the charging capacity oflithium-ion batteries can be accelerated by exposure to elevatedtemperatures. Storing a fully charged device in a location with atemperature outside the long-term storage temperature rangecan significantly reduce its recharging capacity.When you do not plan to use the handheld device for severalmonths, the battery should be removed. Stored data is not lostwhen the battery is removed.When you do not plan to use the collar for several months, thebattery should be charged to about 50%. The device should bestored in a cool, dry place with temperatures around the typicalhousehold level. After storage, the collar should be fullyrecharged before use.Maximizing the Battery LifeYou can do several things to extend the life of the batteries inthe handheld device and collar.• Reduce the backlight brightness (Adjusting the BacklightBrightness).Device Information 13
