Please, be sure to read thismanual before using your phone.And keep the manual afterreading it and use any time youhave a question. ii FCC RF EXPOSURE INFORMATION In August 1996 the Federal Communications Commission (FCC) ofthe United States with its action in Report and Order FCC 96-326adopted an updated safety standard for human exposure to radiofrequency electromagnetic energy emitted by FCC regulatedtransmitters. Those guidelines are consistent with the safetystandard previously set by both U.S. and international standardsbodies. The design of this phone complies with the FCCguidelines and these international standards. Use only the supplied or an approved antenna. Unauthorizedantennas, modifications, or attachments could impair call quality,damage the phone, or result in violation of FCC regulations.Do not use the phone with a damaged antenna. If a damagedantenna comes into contact with the skin, a minor burn mayresult. Please contact your local dealer for replacement antenna.Body-worn OperationThis device was tested for typical body-worn operations usingthe optional belt-clip/holster placed 1.0 inch (2.5cm) from the body . T o comply with FCC RF exposure requirements, a minimum separation distance of 1.0 inch (2.5cm) must be maintained between the user’ s body and the phone, including the antenna, whether extended or retracted. The use of third-party belt-clips/holsters with no metallic components that provide the minimumseparation distance of 1.0 inch (2.5cm) can be used to satisfy FCC RF exposure requirements. The use of non-testedaccessories or other body-worn operations may not comply withFCC RF exposure requirements and should be avoided. Contactyour local dealer for optional accessory items.Vehicle Mounted External Antenna (optional, if available.)A minimum separation distance of 7.9 inches (20cm) must bemaintained Between a person and the vehicle mounted externalantenna to satisfy FCC RF exposure requirements.For more information about RF exposure, please visit the FCCwebsite at www .fcc.gov i SAR Information & FCC ID Labeling THIS MODEL PHONE MEETS THE GOVERNMENT’S REQUIREMENTSFOR EXPOSURE TO RADIO WAVES.Your wireless phone is a radio transmitter and receiver. It is designedand manufactured not to exceed the emission limits for exposure toradiofrequency (RF) energy set by the Federal CommunicationsCommission of the U.S. Government. These limits are part ofcomprehensive guidelines and establish permitted levels of RFenergy for the general population. The guidelines are based onstandards that were developed by independent scientificorganizations through periodic and thorough evaluation of scientificstudies. The standards include a substantial safety margin designedto assure the safety of all persons, regardless of age and health.The exposure standard for wireless mobile phones employs a unit ofmeasurement know as the Specific Absorption Rate, or SAR. TheSAR limit set by the FCC is 1.6W/kg.* Tests for SAR are conductedusing standard operating positions specified by the FCC with thephone transmitting at its highest certified power level in all testedfrequency bands. Although the SAR is determined at the highestcertified power level, the actual SAR level of the phone whileoperating can be well below the maximum value. This is because thephone is designed to operate at multiple power levels so as to useonly the power required to reach the network. In general, the closeryou are to a wireless base station antenna, the lower the poweroutput.Before a phone model is available for sale to the public, it must betested and certified to the FCC that it does not exceed the limitestablished by the government-adopted requirement for safeexposure. The tests are performed in positions and locations (e.g., atthe ear and worn on the body) as required by the FCC for eachmodel. The highest SAR value for this model phone when tested foruse at the ear is XXXXX and when worn on the body, as described in this user guide, is XXXXX . (Body-worn measurements differ among phone models, depending upon available accessories and FCCrequirements). While there may be differences between the SARlevels of various phones and at various positions, they all meet thegovernment requirement for safe exposure. iii 1 ContentsUnpacking . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 Your PhonePhone Layout . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8 Display . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 11 Service Light . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 13 Getting Started Installing the Battery . . . . . . . . . . . . . . . . . . . . . . . . . . 14 Charging a Battery . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16 Switching the Phone On/Off . . . . . . . . . . . . . . . . . . . . . 18 Locking Your Phone . . . . . . . . . . . . . . . . . . . . . . . . . . . 19 General Functions Making a Call . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 20 Adjusting the Volume . . . . . . . . . . . . . . . . . . . . . . . . . . 22 Answering a Call . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 22 Viewing Missed Calls . . . . . . . . . . . . . . . . . . . . . . . . . . 23 Quick-switching to Silent Mode . . . . . . . . . . . . . . . . . . . . 25 Selecting Functions and OptionsUsing the Soft Keys . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 26 Selecting Functions and Options . . . . . . . . . . . . . . . . . . . 27 Example: Setting the Display Language . . . . . . . . . . . . 28 Phonebook Storing a Phone Number with a Name . . . . . . . .…
