This radio is NOT Intended for use by theGeneral Population in an uncontrolled environment .This radio is not designed for use by the general population and is restricted tooccupational users only, where the operator has control of his or RF exposure .Safety Information For GMRS UNITYour wireless handheld portable transceiver contains a low power transmitter. Whenthe TALK button is pushed it sends out radio frequency (RF) signals . This device isauthorized to operate at a duty factor not to exceed 50% In August 1996,the FederalCommunications Commission (FCC) adopted RF exposure guidelines with safetylevels for handheld wireless devices.To ensure that your exposure to RF electromagnetic energy is within the FCCallowable limits for occupational use ,always adhere to the following guldeilnes:. DO NOT operate the radio without a proper antenna attached , as this maydamage the radio and also cause you to exceed FCC RF exposure limits . A properantenna is the antenna supplied with this radio by the manufacturer or an antennaspecifically authorized by the manufacturer for use with this radio.. DO NOT transmit for more than 50% of total radio use time (50% duty cycle)Transmitting more than 50% of the time can cause FCC RF exposure compliancerequirements to be exceeded..ALWAYS use authorized accessories antennas, batteries,belt clips, speaker/mic,etc). Use of unauthorized accessories can cause the FCC RF exposurecompliance requirements to be exceeded.ALWAYS keep the antenna at least 2.5cm (1 inch) away from the body whentransmitting ,If you wear the handset on your body while using the headsetaccessory, DO NOT TRANSMIT. The GM-22 supplied belt clip is for storagepurposes ONLY. This is to ensure FCC RF exposure compliance requirements arenot exceeded. To provide the recipients of your transmission the best sound quality,hold the antenna at least 5cm(2 inches) from the mouth, and slightly off to one side. SAFETY TRAINING INFORMATION 4 ADJUSTMENT: REPLACEMENT or substitution of transistors,regular diodes or other parts of a unique nature, with parts otherthan those recommended by Columbia, may cause a violation ofthe technical regulations of part 95 of the FCC Rules, or violation ofType Acceptance requirements of Part 2 of the Rules.NOTE: This equipment has been tested and found to comply withthe limits for a Class B digital device, pursuant to Part 15 of theFCC Rules These limits are designed to provide reasonableprotection against harmful interference in a residential installation.This equipment generates, uses and can radiate radio frequencyenergy and, if not installed and used in accordance with theinstructions, may cause harmful interference to radiocommunications. However, there is no guarantee that interferencewill not occur in a particular installation. If this equipment doescause harmful interference to radio or television reception, whichcan be determined by turning the equipment off and on, the user isencouraged to try to correct the interference by one or more of thefollowing measures:• Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Consult the dealer or an experienced radio/TV technician for help. This device complies with Part 15 of the FCC Rules. Operation issubject to the following condition: this device must accept anyinterference received, including interference that may causeundesired operation.

CIRCIUT DESCRIPTION MODEL: 1. Receiver Section Radio Signal received by the Antenna, passing through the band pass filter T5 T3 and T8.The RF amplified by Q1 and T6 via 3361CP with XTAL1 three times Self-oscillator signal formed interval frequency, to get intermediate-frequency signals 455Hz. The signal is amplified restrictedly and demodulated by volume control and audio amplifiers Q8 Q7. the sound is then produced by speaker. 2.Transimtter Section In the transmitter section audio signal amplified by Mic Q2 and Q3, and then demodulated with circuit of crystal that formed by Q4 and D2 The signal amplified threefold by Q5. That via low pass filter and is connected the antenna output. 4.POWER SUPPLY Supply voltage of 9v dc is needed to power onwhole circuitry by a 9v battery.

- 1 - CIRCUIT DESCRIPTION 1. RECEIVER SECTION Radio Frequency signal received by the antenna (ANT1), passing through the Low Pass Filter (L1, L2, L22, C2-C4, C153). The RF signal is then amplified by Low Noise Amplifier Q1 and passes through a Band Pass Filter (FL1 = 465MHz). The filtered signal within the range of 462 MHz – 467 MHz is then mixed with the first local oscillator signal from the Voltage Controlled Oscillator (VCO) circuit (Q9,Q10, D4, L16) through Q8, a portion of VCO signal is then feedback to the PLL IC (IC2) for phase comparison generating a stable RX frequency, the output signal is filtered by FL2 (21.7 MHz) which is the first Intermediate Frequency (IF) and is then amplified by Q3. The IF signal is fed to the discriminator IC1 pin 16 which is then mixed with the second local oscillator supplied by crystal X1 (21.25 MHz) to produced a reduced second IF signal which is then filtered by FL3 (KTM450HTW). Demodulated signal is recovered through correct adjustment of IF tank coil (IFT1) and the internal discriminator circuit of IC1. The recovered Audio signal is outputted at pin 9 of IC1 and then processed through filtering done by IC7 circuit, the fully recovered audio signal is then further amplified by Power Amplifier IC3. An audible sound is therefore produce by the speaker SPK100, which can be varied digitally from the CPU pins 76 – 79 and the corresponding series of resistors R31 – R34. 2. TRANSMITTER SECTION PTT switch (SW7) when pushed triggers the Transmitter Circuit “ON”, the voice signal generates by the surrounding noise passes through the microphone MIC100 where mechanical to electrical transformation occurs, the electrical transformed signal is then filtered by a Band Pass Filter IC6, and Q23. The output signal is Modulated by a modulator circuit with a varactor diode D4 and L16. The external components from Q9,Q10 form a VCO Circuit which generates the required oscillating frequency for transmission, a portion of this signal is feedback to the PLL IC2 pin 14 for phase comparison in order to produce a stabilized TX frequency. The modulated signal is then amplified by a Cascaded Amplifier Circuit Q6,Q17 and Q7 and again amplified by Q4 and Q5 to produce a sufficient Radio Frequency signal emitted by the Antenna (ANT1). 3. CALL TRANSMISSION By pushing the CALL key, a signal is detected by the CPU (IC8), a CALL data is then produced by the CPU. This data passes through the Band Pass Filter IC6C and modulated by the varactor diode D4 and L16. The signal follows it’s conventional transmission section path through the antenna. - 2 - 4. BATTERY LOW DETECTION Battery Low Detection is controlled by the CPU pin 43 as detected on the LCD 1, however a voltage divider circuit R64 and R65 serve as the stabilize reference voltage for the CPU to process its detection. 5. SQUELCH DETECTION Supported by the linear IC circuit (IC1), a resistor R12 sets the level of detection and Diode D5 acts as a comparator circuit interface with the CPU. 6. POWER SUPPLY Supply voltage of 6.0 Volts dc is needed to power “ON” the whole circuitry, by four (4) batteries “AAA” size. - 3 - FREQUENCY CHART CHANNEL FREQUENCY (MHz) CHANNEL FREQUENCY (MHz) 1 462.5625 12 467.6625 2 462.5875 13 467.6875 3 462.6125 14 467.7125 4 462.6375 15 462.5500 5 462.6625 16 462.5750 6 462.6875 17 462.6000 7 462.7125 18 462.6250 8 467.5625 19 462.6500 9 467.5875 20 462.6750 10 467.6125 21 462.7000 11 467.6375 22 462.7250 CTCSS CODE FREQUENCY CHART CODE FREQUENCY (Hz) CODE FREQUENCY (Hz) 1 67.0 20 131.8 2 71.9 21 136.5 3 74.4 22 141.3 4 77.0 23 146.2 5 79.7 24 151.4 6 82.5 25 156.7 7 85.4 26 162.2 8 88.5 27 167.9 9 91.5 28 173.8 10 94.8 29 179.9 11 97.4 30 186.2 12 100.0 31 192.8 13 103.5 32 203.5 14 107.2 33 210.7 15 110.9 34 218.1 16 114.8 35 225.7 17 118.8 36 233.6 18 123.0 37 241.8 19 127.3 38 250.3
