Understanding How Your Phone Operates
Your phone is basically a radio transmitter and receiver. When it's
turned on, it receives and transmits radio frequency (RF) signals.
When you use your phone, the system handling your call controls the
power level.
Allow only qualified personnel to service your phone
Allowing unqualified personnel to service your phone may result in
damage to your phone and will void your warranty.
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 and memory cards with care
Do not remove a card while the phone is transferring or accessing
•
information, as this could result in loss of data and/or damage to the
card or phone.
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.
