ID Label/Location Info

APPENDIX A - FCC ID LABELING AND LOCATION Proposed FCC ID Labeling Proposed FCC ID Location Bottom View of EUT / Proposed Label Location Labeling Requirement Each equipment for which a type acceptance applications is filed on or after May 1, 1981, shall bear an identification plate or label pursuant to §2.295 (Identification of Equipment) and §2.926 (FCC identifier) In August 1996 the Federal Communications Commissions (FCC) adopted RF exposure guidelines with safety levels for hand-held wireless devices. Generally users manual contains a RF exposure statement to indicate compliance with FCC requirements. The users manual should also contain required information and instruction pursuant to 95.653.

Parts List/Tune Up Info

CB Module Tuning Procedure 1. RX TUNING 1.VCO Adjust TC 20P variable capacitor till tolerance of 10MHz reference point is within ± 100Hz.(measure at TP8 by cymometer) Adjust T12 coil, let VCO output is 1.9V ± 0.2V at 40CH.(Measure point is at TP3 by mechanical Voltage meter) 2. TX. Press TEST BOX AM/FM button to switch between AM and FM 2.1 AM/FM: Press PTT, adjust TC ( Frequency Tolerance TUNING), so that the output frequency is similar to desire channel such as 27.405MHZ for channel 40. 2.2 AM: adjust VR2 (AM MODULATION TUNING) to let AM MOD at 80%~85% and MAX is not over 100%. 2.3 AM/FM: tune T6 T7 T8 and VR200(TX POWER /TX DIST TUNING) to adjust the TX POWER and find out the distortion is minimum point. (AM AT 80% MOD, DIST is less than 10%; FM DIST is less than 8%). After that we have to tune the TX Power within 3.6W to 4W by adjusting VR200. 2.4 FM: Adjusting VR4 (Frequency Deviation) to let FM frequency shift between 1.7K~1.9K and Maximum is not over 2K. 3. RX TUNING . Press TEST BOX AM/FM button to switch between AM and FM. 3.1 AM/FM: Adjust L1~L3, T1, T2 to make the best sensitivity and S/N. It should be at 12dB SINAD and the S/N is at least –109dB.. DC 12.7V Test Box SAMPLE RF Communications Spectrum Analyzer 3.2 FM : AdjustT3(SENSITIVITY AND S/N) to let the SINAD be the best.. 3.3 AM/FM : Adjust VR1(AUDIO OUTPUT) to let the audio output for FM 0.1~0.32V and AM 0.12~0.16V 3.4 Adjust VR20(SQ), when INPUT is 62dBuV and OUTPUT would be 3.8V. Testing Point is at TP1. 2.WX Tuning Description: WX is just a 1050Hz signal warning system. A. Frequency reference point is as TP5. It should be 10.25MHz ± 60Hz. B. The voltage at TP6 should be 1.5 to 1.75V. If not, tune L6 till get the desired value C. Set the testing point at the output of TP4, tune T4 till getting maximum sensitivity and minimum distortion. D. Set the testing point at TP10 for 1050Hz signal testing. Usually, voltage at TP10 should be high (4.9V). Upon receipt 1050Hz signal, the voltage should be low (0V). The above testing is following ETS300-135 standard for FM, EIA/TIA-382-A for AM including ( FCC/CE and client requirement) PREPARED BY : Mr. YK Liu APPROVED BY : Date: 6-Apr-05

RF Exposure Info

§1.1307(b)(1) & §2.1091 - RF EXPOSURE According to §15.247(b)(4) and §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. According to §1.1310 and §2.1093 RF exposure is calculated. Limits for Maximum Permissive Exposure (MPE) Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm 2 ) Averaging Time (minute) Limits for General Population/Uncontrolled Exposure 0.3-1.34 614 1.63 *(100) 30 1.34-30 824/f 2.19/f *(180/f 2 ) 30 30-300 27.5 0.073 0.2 30 300-1500 / / f/1500 30 1500-15000 / / 1.0 30 f = frequency in MHz * = Plane-wave equivalent power density MPE Prediction Predication of MPE limit at a given distance Equation from page 18 of OET Bulletin 65, Edition 97-01 S = PG/4πR² Where: S = power density P = power input to antenna G = power gain of the antenna in the direction of interest relative to an isotropic radiator R = distance to the center of radiation of the antenna Maximum peak output power at antenna input terminal: 36 (dBm ) Maximum peak output power at antenna input terminal: 3981.07 (mW) Predication frequency: 27 (MHz) Antenna Gain (typical): 0 (dBi) Maximum antenna gain: 1 (numeric) MPE limit for uncontrolled exposure at prediction frequency: 0.25 (mW/cm^2) Power density at predication distance: 40 cm Test Result The predicted distance at 0.25mW/cm 2 power density level is 40cm. The EUT is defined as mobile device.
