INSTALLATION NOTES

The installation of this equipment should be made in such a manner as to respect the EC recommended electromagnetic field exposure limits (1999/519/EC). The maximum RF power available from this device is 25 watts. The antenna should be installed as high as possible for maximum efficiency and that this installation height should be at least 5 meters above ground (or accessible) level. In the case where an antenna cannot be installed at a reasonable height, then the transmitter should neither be continuously operated for long periods if any person is within 5 meters of the antenna, nor operated at all if any person is touching the antenna. In all cases any possible risk depends on the transmitter being activated for long periods. (actual recommendation limits are specied as an average of 6 minutes) Normally the transmitter is not active for long periods of time. Some radio licenses will require that a timer circuit automatically cuts the transmitter after 12 minutes etc. Similarly some types of transmitter, SSB, CW, AM, etc. have a lower average output power and the perceived risk is even lower.

SCAN OPERATION

I Scan types
Scanning is an efcient way to locate signals quickly over a wide frequency range. The transceiver has priority scan and normal scan. Set the tag channels (scanned channel) before scanning. Clear the tag channels which inconveniently stop scanning, such as channels used for digital communication. Choose priority or normal scan in set mode. (p. 15)

PRIORITY SCAN

CH 01 CH 02

NORMAL SCAN

Priority scan searches through all tag channels in sequence while monitoring Channel 16. When a signal is detected on Channel 16, scan pauses until the signal disappears; when a signal is detected on a channel other than Channel 16, scan becomes dualwatch until the signal disappears. 12
Normal scan, like priority scan, searches through all tag channels in sequence. However, unlike priority scan, Channel 16 is not checked unless Channel 16 is set as a tag channel.

SECTION 4 CIRCUIT DESCRIPTION

4-1 RECEIVER CIRCUITS

4-1-1 ANTENNA SWITCHING CIRCUIT (MAIN-E UNIT)
The antenna switching circuit functions as a low-pass filter while receiving and as resonator circuit while transmitting. The circuit does not allow transmit signals to enter receiver circuits. Received signals enter the MAIN-E unit from the antenna connector and pass through the low-pass filter (L21, L22, C127, C130, C133). The signals are then applied to the RF circuit via the antenna switching circuit (D14, D21, L31, C141, C142). The signals from the RF circuit are mixed with the VCO signals at the 1st mixer circuit (Q22) to produce a 21.7 MHz 1st IF signal. The 1st IF signal is applied to two crystal filters (FI1, FI2) to suppress out-of-band signals and is then amplified at the IF amplifier (Q23). The amplified signal is applied to the 2nd mixer circuit (IC2).

4-1-4 2ND IF AND DEMODULATOR CIRCUITS (MAIN-E UNIT)
The 2nd mixer circuit converts the 1st IF signal to a 2nd IF signal. A double superheterodyne system (which converts receive signals twice) improves the image rejection ratio and obtains stable receiver gain. The FM IF IC (IC2) contains the 2nd local oscillator, 2nd mixer, limiter amplifier, quadrature detector, and noise detector circuits, etc. The 1st IF signal from Q23 is applied to the 2nd mixer section of IC2 (pin 16), and is mixed with a 21.25 MHz 2nd LO signal generated at the PLL circuit using the reference frequency (21.25 MHz) to produce a 450 kHz 2nd IF signal. The 2nd IF signal from IC2 (pin 3) is passed through the ceramic filter (FI3), where unwanted signals are suppressed, and is then applied to the 2nd IF (limiter) amplifier in IC2 (pin 5). The signal is applied to the FM detector section in IC2 for demodulation into AF signals. The FM detector circuit employs a quadrature detection method (linear phase detection), which uses a ceramic discriminator (X2) for phase delay to obtain a non-adjusting circuit. The detected signal from IC2 (pin 9) is applied to the AF circuit.
4-1-2 RF CIRCUIT (MAIN-E UNIT)
The RF circuit amplifies signals within the range of frequency coverage and filters out-of-band signals. The signals from the antenna switching circuit pass through a tunable bandpass filter (D25, L35, C150, C152) where the object signals are applied to the RF amplifier circuit (Q21). The amplified signals at Q21are applied to the 3-stage tunable bandpass filter (D26-D28, L36, L38, L39, C161, C162, C164, C173-C178) to suppress unwanted signals and improve the selectivity. The signals are then applied to the 1st mixer circuit (Q22).
4-1-3 1ST MIXER AND 1ST IF CIRCUITS (MAIN-E UNIT)
The 1st mixer circuit converts the received signal to a fixed frequency of the 1st IF signal with a 1st LO (VCO output) frequency. By changing the 1st LO frequency, only the desired frequency will be passed through two crystal filters at the next stage of the mixer. 2ND IF AND DEMODULATOR CIRCUITS

4-1-5 AF AMPLIFIER CIRCUIT (MAIN-E AND FRONT UNITS)
The AF amplifier circuit amplifies the detected signals to drive a speaker. The AF circuit includes an AF mute circuit for the squelch. AF signals from IC2 (pin 9) are applied to the de-emphasis circuit (R231, C232). The de-emphasis circuit is an integrated circuit with frequency characteristic of 6 dB/octave. The integrated signals pass through the bandpass filter (Q31, R232, R234R237, C233, C234) to suppress unwanted noise signals. The filtered signals are applied to the AF mute circuit (IC4), and then passes through the [VOLUME] control (VR board; R1) via the VOL1 signal. The signals are applied to the AF power amplifier (IC9, pin 1). The output signal from IC9 (pin 4) drives the internal (external) speaker.

4-3-2 TX AND RX LOOP (MAIN-E UNIT)
The generated signal at the VCO (Q4, Q5, D3, D4) enters the PLL IC (IC1, pin 2) and is divided at the programmable divider section and is then applied to the phase detector section. The phase detector compares the input signal with a reference frequency, and then outputs the out-of-phase signal (pulse-type signal) from pin 8. The pulse-type signal is converted into DC voltage (lock voltage) at the loop filter (R7R9, R41, C4, C5, C43, C44), and is then applied to varactor diodes (D3, D4) of the VCO to stabilize the oscillated frequency.
RESET CIRCUIT IC2 is a reset IC. When turn power ON, IC2 outputs a reset signal (LOW pulse) to the CPU (IC1, pin 15) via the RES line. LOW BATTERY DETECTOR VCC voltage is divided by R84, R85 and is applied to the low battery detector section in the CPU (IC1, pin 91) via the LBAT line. DIMMER CIRCUIT The CPU (IC1), Q1, Q2 and Q3 are dimmer circuit and control the 4 steps the LCD backlight (DS2DS7).
4-3-4 VCO CIRCUIT (MAIN-E UNIT)
The VCO outputs from Q4, Q5 are buffer-amplified at the buffer amplifiers (Q6 and Q7), and are then sent to the Tx/Rx switch (D7 and D8). The receive LO signal is applied to the 1st mixer circuit (Q22) through a low-pass filter, and the transmit signal is applied to the pre-drive amplifier (Q10). A portion of the VCO output is reapplied to the PLL IC (IC1, pin 2) via the buffer amplifier (Q3).
4-6 POWER SUPPLY CIRCUITS
VOLTAGE LINES LINE HV HVS VCC DESCRIPTION The voltage from the connected DC power supply. Same voltage as the HV line which is passed through the [PWR] switch (VR unit; R1). Same voltage as the HVS line. The voltage is applied to the optional DSC controller (DS-100). Common 5 V converted from the VCC line at the 5V regulator circuit (MAIN-E unit; IC10).

4-4 ATIS AND DSC CIRCUITS
4-4-1 ATIS ENCODE CIRCUIT (LOGIC-E BOARD AND MAIN-E UNIT)
The FSK signal of ATIS created at CPU (LOGIC-E board; IC1) is passed through the ladder type D/A convertor (R41R56) to convert into the analog signal. The analog signal is applied to the buffer amplifier (LOGIC-E board; IC9), and then applied to the mixer circuit (MAIN-E unit; IC7, pins 1, 2) to mix with signals from the microphone. The signal passes through the low-pass filter (MAIN-E unit; IC8, pins 1, 3) and is then applied to the VCO circuit as modulation signal.
