Read and understand all instructions. 2. Follow all warnings and instruc- tions marked on the telephone. 3. Do not use this telephone near a bath tub, wash basin, kitchen sink or laundry tub, in a wet basement, near a swimming pool or anywhere else there is water. 4. Avoid using a telephone (other than a cordless type) during a storm. There may be a remote risk of electrical shock from lightning. 5. Do not use the telephone to report a gas leak in the vicinity of the leak. 6. Unplug this telephone from the wall outlets before cleaning. Do not use liquid cleaners or aerosol cleaners on the telephone. Use a damp cloth for cleaning. 7. Place this telephone on a stable surface. Serious damage and/or injury may result if the telephone falls. 8. Do not cover the slots and open- ings on this telephone. This telephone should never be placed near or over a radiator or heat register. This tele- phone should not be placed in a built-in installation unless proper ventilation is provided. 9. Operate this telephone using the electrical voltage as stated on the base unit or in the owner’s manual. If you are not sure of the voltage in your home, consult your dealer or local power company. 10. Do not place anything on the power cord. Install the telephone where no one will step or trip on the cord. 11. Do not overload wall outlets or extension cords as this can increase the risk of fire or electrical shock. 12. Never push any objects through the slots in the telephone. They can touch dangerous voltage points or short out parts that could result in a risk of fire or electrical shock. Never spill liquid of any kind on the telephone. 13. To reduce the risk of electrical shock, do not take this phone apart. Opening or removing covers may expose you to dangerous voltages or other risks. Incorrect reassembly can cause electric shock when the appliance is subsequently used. 14. Unplug this product from the wall outlet and refer servicing to the manufacturer under the following conditions: A. When the power supply cord or plug is frayed or damaged. B. If liquid has been spilled into the product. C. If the telephone has been exposed to rain or water. D. If the telephone does not operate normally by following the operating instructions. Adjust only those controls that are covered by the operating 5 IMPORTANT SAFETY INSTRUCTIONS SAVE THESE INSTRUCTIONS instructions. Improper adjust- ment may require extensive work by a qualified technician to restore the telephone to normal operation. E. If the telephone has been dropped or the case has been damaged. F.

Revision: 02 Page 32 of 39 10. C4230 Basic Operation (Base and Handset) 10.1 Registration Before the handset can make a call, it has to register to a base unit. This can be done either manually or automatically. For C4230, the following identification codes are generated during power up. A. Handset IPEI (International Portable Equipment Identity) code: Bits (0 -> 5) - 000000; Bits (6 -> 15) - EMC (Equipment Manufacturer’s Code) code (DSPG 0x010); Bits (16 -> 35) - PESN (Portable Equipment Serial Number) (524K combinations) B. Base RFPI (Radio Fixed Part Identity) code: Bits (0 -> 7) - Frequency information; Bits (8 -> 9) - 00; Bits (10 -> 19) - EMC code (DSPG 0x010); Bits (20 -> 36) – FPN (Fixed Part Number) (65K combinations); Bits (37 -> 39) - 000. These codes are registered to each other during registration process. In addition, a 128 bit authentication code (made up of four 32 bits short authentication code) is generated randomly through the registration process. These codes are checked when the handset/base communicate with each other. Registration (Manual Method): Press the handset “MENU” button or the “MENU” softkey. Press “UP” / “DOWN” button to scroll to “Initial Setup”. Press “SELECT” softkey. LCD will show the selection arrow pointing at “REGISTRATION”. Press and hold the base “PAGE” switch for ~2 seconds until the “INUSE” LED on the base blinks. Press the “SELECT” softkey on the handset. The base and handset will start the registration process. Registration (Automatic Method): Connect AC power to the base unit first.

INTERTEK TESTING SERVICES FCC ID:ACEC4230 RF exposure - 2 of 2 For Maximum Permissible Exposure (MPE) evaluation of the base unit, the maximum power density at 20 cm from this mobile transmitter shall be less than the General Population / Uncontrolled MPE limit in OET Bulletin 65. For the base unit of tested model of C4220, the maximum field strength measured (FS) was 118.9 dBμV/m. The distance (D) between the antenna and the equipment under test (EUT) was 3 meters. And the maximum source-based time-averaging duty factor in four-handsets operation is 39.2%. From these data, the exposed power density at a distance (R) of 20cm from the center of radiation of the antenna can be calculated according to OET Bulletin 65 as follow: The radiated power = (FS*D) 2 / 30 = 232.87 mW The radiated (EIRP) source-based time-averaging output power = (232.87 * 0.392) mW = 91.29 mW The power density at 20 cm from the antenna = EIRP / 4πR 2 = 0.0182 mW cm -2 In the frequency range of 1,500 - 100,000MHz, the MPE limit is 1.0 mWcm -2 for general population and uncontrolled exposure. As the measured power density at 20cm from the transmitter is lower than the MPE limit, the compliance to the MPE limit can be ensured by indicating the minimum 20cm separation between the transmitter's radiating structures and body of the user or nearby persons. The following RF exposure statement is proposed to be included in the user manual: “ FCC RF Radiation Exposure Statement Caution: To maintain compliance with the FCC’s RF exposure guidelines, place the base unit at least 20cm from nearby persons.”

From these data, the exposed power density at a distance (R) of 20cm from the center of radiation of the antenna can be calculated according to OET Bulletin 65 as follow: The radiated power = (FS*D) 2 / 30 = 54.59 mW The radiated (EIRP) source-based time-averaging output power = (54.59 * 0.392) mW = 21.40 mW The power density at 20 cm from the antenna = EIRP / 4πR 2 = 0.0043 mW cm -2 In the frequency range of 1,500 - 100,000MHz, the MPE limit is 1.0 mWcm -2 for general population and uncontrolled exposure.
