Some of the enhancements are described in detail below.
For availability of the enhancements, please check with
your local dealer. A few practical rules for enhancements
operation:
• Keep the enhancements out of small children's reach.
• When you disconnect the power cord of any accessory,
grasp and pull the plug, not the cord.
• Check regularly that all mobile phone equipment in a
vehicle is mounted and operating properly.
Use only batteries, chargers and enhancements
approved by the phone manufacturer. The use of any
other types may invalidate any approval or warranty
applying to the phone, and may be dangerous.
