Battery information
The full performance of a new battery is achieved only after two of three complete charge and discharge cycles. Do not leave a fully charged battery connected to a charger since overcharging may shorten battery lifetime. If left unused, a battery will lose power with passage of time, so if the device is not used for long time it is suggested to charge once in a month time. Leaving the device in hot or cold places, such as in closed car in summer or winter conditions will reduce the capacity and lifetime of the battery. Should always try to keep the battery between 15 ℃ and 25 ℃. Battery performance is particularly limited in temperatures well below freezing .Do not dispose of batteries in a fire as they may explode .Battery may also explode if damaged.
Safety instruction
The following suggestions will help you effectively use the device for long time.
- Keep the adapter in dry place. Water, moisture and all kinds of liquids or moisture can damage or corrode the electronic circuit.
- Keep the device in clean place. Dust can damage the device.
- Do not use equipment stored when overheated, high temperature will shorten the life of electronic devices, damage batteries, make some plastic parts deform or melt.
- Do not use equipment if it was stored a cold place because when the device comes to room temperature, moisture will get deposited, which will damage the chipset.
- Do not try to un assemble the device.
- Do not use strong chemicals, detergent or detergent to clean the device.
- Keep the unit away from children.
