Flashlight Introduction 5 Component Guide Battery Installation To use the radio, you must install 4 AAA size batteries. Caution: incorrect positioning of the batteries can damage both the batteries and the unit. To install the batteries: •Remove the belt clip by pulling the tab on the top of the belt clip back, and sliding it up and off of the unit. •Pull the battery door lock tab down to release the battery cover. •lnsert four AAA batteries. Position the batteries according to the polarity markings on the plastic. •Replace the battery cover. Snap the lock tab and belt clip back into place. connecting the adaptor To use the unit with an AC/DC Adaptor rechargeable batteries must be used. Lift the rubber flap on the top of the unit to expose the jack. Insert the round connector (OD 2.5mm) of the7.5V DC/100mA AC/DC adaptor* into the SPK/MIC/CHG jack on top of the unit. Note The unit should be turned OFF in order to charge the batteries properly.If the unit is turned ON and placed for charging the charge current is too low for the battery to charge up as the Setting Up Your FRS Radio Setting Up Your FRS Radio 6 unit is still using power.There is no charge indicator during charging at OFF mode.It takes approximately 7 to 10 hours to fully charge the batteries if they are at the their lowest lever. WARNING DO NOT CHARGE THIS UNIT USING AN AC/DC ADAPTOR* WITH REGULAR AAA ALKALINE BATTERIES INSTALLED.USE ONLY THE AC/DC ADAPTOR WITH AAA RECHARGEABLE BATTERIES • Do not mix old and new batteries. • Do not mix alkaline, standard (carbon-zinc), or rechargeable batteries. * The AC/DC adaptor and rechargeable batteries are sold separately. Battery Meter The battery meter is located in the bottom left corner of the LCD display panel on the unit. It looks like a battery with vertical bar inside. As the power is used up, the bar will disappear. Low Battery Indicator When the batteries need to be changed, the battery vertical bar inside will disappear. To ensure uninterrupted communication, replace the Setting Up Your FRS Radio Sett…

- 1 - CIRCUIT DESCRIPTION 1. RECEIVER SECTION Radio Frequency signal received by the antenna (ANT1), passing through the Low Pass Filter (L1,L3, C2-C5). The RF signal is then amplified by Low Noise Amplifier Q1 and passes through a Band Pass Filter of L16,19,C14,16,82,83. The filtered signal within the range of 446 MHz is then mixed with the first local oscillator signal from the Voltage Controlled Oscillator (VCO) circuit (Q11,Q10, D7, L18) through Q3, 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 Q4. 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 Q20, the fully recovered audio signal is then further amplified by Power Amplifier IC101. An audible sound is therefore produce by the speaker SPK100, which can be varied digitally from the CPU pins 29,20,31 and the corresponding series of resistors R4,R16,R66. 2. TRANSMITTER SECTION PTT switch (SW1) when pushed triggers the Transmitter Circuit “ON”, the voice signal generates by the surrounding noise passes through the microphone MIC1 where mechanical to electrical transformation occurs, the electrical transformed signal is then filtered by Q18. The output signal is Modulated by a modulator circuit with a varactor diode D7 and L18. The external components from Q10,Q11 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 Q7 and Q8 and again amplified by Q5 and Q6 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 (IC105), a CALL data is then produced by the CPU. This data passes through the Low Pass Filter Q18 and modulated by the varactor diode D7 and L18. 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 20 as detected on the LCD 1, however a voltage divider circuit R57 and R54 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 R21 sets the level of detection and Diode D3 acts as a comparator circuit interface with the CPU. 6. POWER SUPPLY Supply voltage of 6 Volts dc is needed to power “ON” the whole circuitry, by four (4) batteries “AAA” size.
