ADVANCED MOBILE SOLUTIONS, INC AIR MAGIC WIRELESS HEADSET & BASE STATION USER’S GUIDE HOW TO USE THE HEADSET AND BASE STATION STEP 1 Plug base station into cigarette lighter outlet. SETP 2 Plug the right angle 2.5mm plug from the base station into the audio receptacle or adapter on the phone. STEP 3 Adjust microphone tip to point to the corner of your mouth and adjust the earhook for proper stability. SETP 4 Turn on the headset by pushing the ON button. During a call, should it be necessary to adjust the receiver volume, push the three step volume button to achieve the correct level. BASE STATION OPERATION • Make sure the second battery pack is in the base station charging receptacle. • The LED on the right side of the base station will display the charging status of the battery, Red is fast charge and Green fully charged. • If the battery power drops below sufficient power level, you will notice a slight increase in background noise. Remove battery pack from the headset and replace it with a freshly charged battery pack from the base station. Place the discharged battery pack from the headset into the base station charger. • The newly charged battery will have a 4 hour on time • Normal charging time for the battery is 2.5 hours. HEADSET OPERATION • During a call, should it be necessary to adjust the receiver volume, push the three step volume button to achieve the correct level. • Transmit and receive range is 5 feet from the base station. If you exceed this range, the headset will generate an out of range tone every four seconds, up to eight times for a total of 32 seconds. When you return back into range the headset will still be linked to the base station. If you stay out of range for more than 32 seconds, the headset will automatically turn off to conserve battery power. At that time the yellow LED will be off, indicating a broken link. • To establish the link, simply turn the headset back on and the yellow LED will be back on showing the link has been established. • If for some reason you experience some interference with other electronic devices such as labtop computer TV set or radio etc. you can change the frequency setting by removing the battery pack from the headset and changing the 2 channel select switch to the other position. CAUTION: • Do not attempt to put on your headset or change the battery while driving. • Only turn off the headset when you leave the car or when you do not wish to use your cellular phone. FCC COMPLIANCE STATEMENT: This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. CAUTION: Changes or modifications not expressly approved by the manufacturer responsible for compliance could void the user’s authority to operate the equipment

Theory of Operation AM1010B and AM1010H Prepared by Kevin Park Version 1.1 1.0 Theory of Operation 1.1 System Abstract: The characterstics of AM1010 is that One Chip IC offers all functions. AURA IC’s Short Range Magnetic Induction ASIC, AB1002 and AH1002 provide audio signal and RF signal for BU(AM1010B Base Unit) and HU(AM1010H Headset Unit). AM1010 IC sends the signal using the method of PWM (Puls Width Modulation) and receives AM modulation signal through LC antenna. Wireless communication’s receiver and transmitter are created by Magnetic Induction and the power consumption is very low and the unwanted emission are minimized. Receiver signal is controlled by AGC(Automatic Gain Controller) and it creates audio signal by IQ-Modulator and Direct Conversion method. Audio signal transmits low noise signal though Compressor and Expender in the IC. ASIC has TX, LO1, LO2 derived by PLL and can choose maximum 2 channels. 1.2 Dimensional Antenna The biggest characteristic of AM1010 is that 3 receiver and transmitter antenna with X,Y,Z axis are built in BU. This method prevents from lowering signal output by the signal direction of Magnetic Induction. Each axis of receiver antenna and transmitter antenna are constructed in the same direction. ASIC of BU do summing the signals from each axis and combines communication signals and then sends the signal by transmitter antenna which finds the strongest signals among the 3 axis antenna. The selection of transmitter antenna continues during communication and BU’s transmitter antenna is selected automatically which is depends on the direction of HU’s transmitter antenna. 1.3 X-Tal, TX, Local Oscillator 1 and 2 The set up for AM1010 wireless frequency is determined by Channel Switch. The channel can have maximum 8. Transmitter frequency is controlled by the internal PLL, according to selected channel value and transmitter frequency is calculated according to the following table. Reference frequency is obtained from X-tal(3.58MHz). TX Oscillator and Fist Local Oscillator and Second Local Oscillator are created internal ASIC. Especially, HU’s wireless frequency can be automatically tracking according to Base’s transmitter frequency. HU’s wireless frequency Tracking can control automatically HU’s Reference frequency by Varactor Diode which is installed inside of HU’s ASIC AH1002. Therefore, for frequency variation due to the environment, HU and BU can maintain the same frequency. 1.4 Modulation After BU and HU pass Compressor equally, communication signals change the internal PWM. The changed signals become Buffering through Inverter IC which connects to external ASIC and AM signals are Radiated through LC antenna. 1.5 AGC(Automatic Gain Control) The signal received by antenna is amplified by input amplifier in internal ASIC. Because the amplifier gain is fixed by RF-load, when the over limit signal sends to antenna, the signal becomes saturated and it causes signal Distortion. To prevent this, AGC (Atomatic Gain Controller) using Transistor Switch is built between antenna and RF-Load. When the internal Gain Controller voltage becomes over the limit level, it will turn on Transistor Switch and reduce the impedance of Rf-load and lower the Gain 1.6 Demodulator After the receiver signal mixes with LO1(First Local Oscillator) inside ASIC and passes 455KHz IF filter outside, it makes communication signal though I-Q modulator. In I-Q modulator, it mixes with LO2 (second Local Oscillator). In BU, separate I-Q modulator is installed where 2 I-Q Modulator will inspect the third axis receiver signal and will transmit to the direction of the antenna which finds the strongest signal. 1.7 OOR (Out of Range Detector) Depending on the demodulated communication signal volume, it sets OOR by comparing the DC size for found Gain Error and externally fixed OOR Range with resistance. BU indicates the status of OOR in Yellow color LED and HU warns the distance Tone signal to the user through speaker. When OOR is set, it mutes the block of internal receiver communication output and prevents the noise signal to go outside through Audio Line.
