Ensure maximum battery and charger life
• Avoid charging batteries for more than a week, as overcharging
may shorten battery life.
• Over time, unused batteries will discharge and must be recharged
before use.
• Disconnect chargers from power sources when not in use.
• Use batteries only for their intended purpose.
Handle SIM cards and memory cards with care
• Do not remove a card while the device is transferring or accessing
information, as this could result in loss of data and/or damage to
the card or device.
• Protect cards from strong shocks, static electricity, and electrical
noise from other devices.
• Frequent writing and erasing will shorten the life span of memory
cards.
• Do not touch gold-coloured contacts or terminals with your fingers
or metal objects. If dirty, wipe the card with a soft cloth.
