Langchao LG (YANTAI) Digital Mobile Technology R&D Co., Ltd Oct 16. 2001 1/24 CU410 User’s Manual For more information about RF exposure, please visit the FCC website at www.fcc.gov FCC RF EXPOSURE INFORMATION In August 1996 the Federal Communications Commission (FCC) of the United States with its action in Report and Order FCC 96-326 adopted an updated safety standard for human exposure to radio frequency electromagnetic energy emitted by FCC regulated transmitters. Those guidelines are consistent with the safety standard previously set by both U.S. and international standards bodies. The design of this phone complies with the FCC guidelines and these international standards. Use only the supplied or an approved antenna. Unauthorized antennas, 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 damaged antenna comes into contact with the skin, a minor burn may result. Please contact your local dealer for replacement antenna. Body-worn Operation This device was tested for typical body-worn operations with the back of the phone kept 1.0 cm. from the body. To maintain compliance with FCC RF exposure requirements, use only belt-clips, holsters or similar accessories that maintain a 1.0 cm. separation distance between the user’s body and the back of the phone, including the antenna, whether extended or retracted. The use of third-party belt-clips, holsters and similar accessories should not contain metallic components in its assembly. The use of accessories that do not satisfy these requirements may not comply with FCC RF exposure requirements, and should be avoided. WARNING!

Soft Key 1: Used to display the function setting menu. Soft Key 2: Used to search through the stored phone numbers and select the function. Up Navigation: When search a character/voice message and scroll through menu items Langchao LG (YANTAI) Digital Mobile Technology R&D Co., Ltd Oct 16. 2001 2/24 vertically. Down Navigation: When search today schedules and scroll through menu items vertically. Left Navigation(<) : Used to connect Internet service and scroll through menu items horizontally. Right Navigation(>) : Used to scroll through menu items horizontally. CLR: If you press this key once, you can erase one digit or character. If you press and hold this key, you can erase all digits. (When enter the phone number) If you press this key once in a menu, you can go back one level and if you press and hold the key in a menu, you can go back to the standby display. - In the standby status, set the manner mode by pressing the # button. (for 2 seconds) - In the standby status, set the lock function by pressing the * button. (for 2 seconds) Alphanumeric keypad: These keys enable you to enter numbers and characters and choose menu items. Hotkey1, Hotkey2, Hotkey3 : These keys use bookmark Battery Charge Level The battery charge level is shown at the top right of the LCD screen on the phone. When the battery charge level becomes low, the low battery sensor will alert you in three ways: Sounding an audible tone, blinking the battery icon outline, and displaying “LOW BATTERY WARNING”. After a short period of time, the power is automatically shut down to prevent any battery damage. Using the Desktop Charger The “CU410” desktop charger has a slot for recharging batteries. The slot accommodates phone and battery pack for charging. Warning! Use only the desktop charger provided with the phone. Using the wrong charger may cause damage to your phone or battery. 1. Plug the charger into a wall outlet. ¢∫ The charger should operate on a 220V source. 2. Insert the phone with an installed battery pack or a battery pack into the charger’s slot. ¢∫ Fit the battery terminal and charger terminal properly. The lamp on the front of the charger should be red. Langchao LG (YANTAI) Digital Mobile Technology R&D Co., Ltd Oct 16. 2001 3/24 If completely discharged, the battery will take about 3 hours to recharge. If you leave the phone on while it is in the desktop charger, the battery will take longer to charge. Chapter 2. Basic Functions Making a Call Whenever you make a call, follow these simple steps: 1. Make sure the phone is turned on. ¢∫ If not, press [END] 2. Enter the phone number with area code, if needed. 3. Press [SND] ¢∫ If the phone is …

(c) 1992 by the Institute of Electrical and Electronics Engineers, Inc., New York, New York 10017.[2] The measurement procedure described in IEEE/ANSI C95.3-1992 Recommended Practice for the Measurement of Potentially Hazardous Electromagnetic Fields - RF and Microwave[3] is used for guidance in measuring SAR due to the RF radiation exposure from the Equipment Under Test (EUT). These criteria for SAR evaluation are similar to those recommended by the National Council on Radiation Protection and Measurements (NCRP) in Biological Effects and Exposure Criteria for Radiofrequency Electromagnetic Fields,” NCRP Report No. 86 (c) NCRP, 1986, Bethesda, MD 20814.[5] SAR is a measure of the rate of energy absorption due to exposure to an RF transmitting source. SAR values have been related to threshold levels for potential biological hazards. 2.2 SAR Definition Specific Absorption Rat…
