Blasting Areas
To avoid interfering with blasting operations, turn Off your phone when in a blasting area or areas posted: "Turn Off Two-Way Radio."
Obey all signs and instructions. (See Flag.)
Potentially Explosive Atmospheres
Turn Off your phone prior to entering any area with a potentially explosive atmosphere, and obey all signs and instructions. Do not
remove, install, or change batteries in such areas. Sparks in such areas could cause an explosion or fire resulting in bodily injury or
even death. (See Flag.)
Areas with a potentially explosive atmosphere are often, but not always, clearly marked. These include fueling areas such as gasoline
stations; below deck on boats; fuel or chemical transfer or storage facilities; vehicles using liquefied petroleum gas (such a propane or
butane); areas where oxygen is used; areas where the air contains chemicals or particles such as grain, dust, or metal powders; and any
other area where you would normally be advised to turned Off your vehicle engine.
Vehicles Equipped with an Air Bag
An air bag inflates with great force. Do not place objects, including either installed or portable wireless equipment, in the area over the
air bag or in the air bag deployment area. If wireless equipment is improperly installed in the vehicle and the air bag inflates, serious
injury could result.
Battery Care and Disposal
Do not leave the phone or the battery in places where the temperature could exceed 140 °F, i.e., on a car dashboard, on a window sill,
in direct sunlight, etc.
Do not put your phone's battery in your mouth as battery electrolytes may be toxic, if swallowed.
Keep the battery away from children. It is not a toy and it could be a choking hazard.
Your phone battery is a sealed unit with no serviceable parts inside; do not attempt to open the battery covering.
Use only a battery approved by NEC for the 525 wireless phone.
Using any battery pack or AC adapter not specified by NEC for use with the 525 may be dangerous and may invalidate any warranty and
approval given to the wireless phone. Do not connect more than one charger at any time.
To ensure the maximum life from your battery, allow the battery to fully discharge at least once a week. To fully discharge the battery,
leave the phone turned on until the message "RECHARGE BATTERY" is displayed and the phone shuts itself Off. If left unused, a fully
charged battery discharges in approximately one month. Store batteries uncharged in a cool, dark, and dry place.
Batteries must be recycled or disposed of properly. Through the AT&T Wireless Reuse and Recycle program, consumers are invited to
bring unwanted phones, accessories, and batteries (regardless of the manufacture or carrier) to an AT&T Wireless retail store for
recycling. Use the website link to find an AT&T Wireless store nearest you:" http://www.attwireless.com/general/storelocator ".
Do not dispose of battery packs in a fire.
O
Turn Off the phone. The wireless
phone can still be a hazard in these
areas even when set in vibrate
mode.
