|I use this in my 1998 car with a tape deck to connect my ipod. I find the fm transmitters annoying, and unreliable. This is much simpler. It was fast fun and easy. Stuck the cassette in plug in my MP3 player and listen to good quality music with no static. Easy Setup","Good Quality".|

IN CASE OF EMERGENCY
If your vessel requires assistance, contact other vessels and the Coast Guard by sending a distress call on Channel 16. Or, transmit your distress call using digital selective calling on Channel 70 (the optional DS-100 (#02) must be installed).
USING CHANNEL 16 DISTRESS CALL PROCEDURE 1. MAYDAY MAYDAY MAYDAY. 2. THIS IS.. (name of vessel) 3. Your call sign or other indication of the vessel (AND 9-digit DSC ID if you have one). 4. LOCATED AT.. (your position) 5. The nature of the distress and assistance required. 6. Any other information which might facilitate the rescue.
USING DIGITAL SELECTIVE CALLING (ch 70)
(DS-100 DSC CONTROLLER is required)
DISTRESS CALL PROCEDURE 1. Push and hold [DISTRESS] on the DS-100 for 5 sec. until you hear 5 short beeps change to one long beep. 2. Wait for an acknowledgment from a coast station.
Channel 16 is automatically selected.

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.

READ ALL INSTRUCTIONS carefully and completely
before using the transceiver.
SAVE THIS INSTRUCTION MANUAL This instruction manual contains important operating instructions for the IC-M401EURO.
RWARNING! NEVER connect the transceiver to an AC
outlet. This may pose a fire hazard or result in an electric shock.
DO NOT use or place the transceiver in areas with temperatures below 20C or above +60C or, in areas subject to direct sunlight, such as the dashboard. AVOID the use of chemical agents such as benzine or alcohol when cleaning, as they may damage the transceiver surfaces. BE CAREFUL! The transceiver rear panel will become
hot when operating continuously for long periods. Place the transceiver in a secure place to avoid inadvertent use by children. After exposure to salt water, clean the transceiver thoroughly with fresh water to avoid corrosion. Do not pour water on the transceiver under the water tap directly.
NEVER connect the transceiver to a power source of more than 16 V DC or using reverse polarity. This will ruin the transceiver. NEVER cut the DC power cable between the DC plug and
fuse holder. If an incorrect connection is made after cutting, the transceiver may be damaged.
NEVER place the transceiver where normal operation of the
vessel may be hindered or where it could cause bodily injury.
KEEP the transceiver at least 1 m away from the ships navigation compass.

Read all rules and regulations pertaining to priorities and keep an up-to-date copy handy. Safety and distress calls take priority over all others. You must monitor Channel 16 when you are not operating on another channel. False or fraudulent distress signals are prohibited and punishable by law.
(2) OPERATORS LICENSE A Restricted Radiotelephone Operator Permit is the license most often held by small vessel radio operators when a radio is not required for safety purposes. The Restricted Radiotelephone Operator Permit must be posted or kept with the operator. Only a licensed radio operator may operate a transceiver. However, non-licensed individuals may talk over a transceiver if a licensed operator starts, supervises, ends the call and makes the necessary log entries. Keep a copy of the current government rules and regulations handy.
Information overheard but not intended for you cannot lawfully be used in any way. Indecent or profane language is prohibited.
(1) SHIP STATION LICENSE You must have a current radio station license before using the transceiver. It is unlawful to operate a ship station which is not licensed. Inquire through your dealer or the appropriate government agency for a Ship-Radiotelephone license application. This government-issued license states the call sign which is your crafts identication for radio purposes. 1

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)
CH 01 CH 02
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.

Pre-driver (Q10: 2SC3775 3)
Reference oscillator (X2: CR-659) YGR amplifier (Q11: 2SC3268) Antenna switching circuit VCO circuit
4-2-2 MODULATION CIRCUIT (MAIN UNIT)
The modulation circuit modulates the VCO oscillating signal (RF signal) using the microphone audio signals. Audio signals from the splatter filter (IC10B) pass through the frequency deviation adjustment pot (R138) and are then applied to the modulation circuit (D2, D3, D4) to change the reactance of D2, D3, D4 and modulate the oscillated signal at the VCO (Q5, Q6).
4-2-3 DRIVE AMPLIFIER CIRCUIT (MAIN UNIT)
The drive amplifier circuit amplifies the VCO oscillating signal to a level needed at the power amplifier.
4-1-6 SQUELCH CIRCUIT (MAIN UNIT AND LOGIC BOARD)
A squelch circuit cuts out AF signals when no RF signals are received. By detecting noise components in the AF signals, the squelch circuit switches the AF mute switch. A portion of the AF signals from the FM IF IC (IC1, pin 9) pass through the squelch adjustment pot (R16), and are then applied to the active filter section (IC1, pin 8). The active filter section amplifies and filters noise components. The filtered signals are applied to the noise detector section and output from pin 14 as the SQL signal. The SQL signal is applied to the CPU (LOGIC board; IC1, pin 90) after being passed through the amplifier (IC13, pins 1, 4). The CPU analyzes the noise condition and outputs the RMUTM, PTTM signals to toggle the AF mute switches (IC12A, IC12B).
The VCO output is buffer-amplified by Q7 and Q9, and is then applied to the Tx/Rx switch (D6). The transmit signal from the Tx/Rx switch is amplified to the pre-drive (Q10) and YGR (Q11) amplifiers to obtain an approximate 300 mW signal level. The amplified signal is then applied to the RF power amplifier (IC3).
4-2-4 POWER AMPLIFIER CIRCUIT (MAIN UNIT)
The power amplifier circuit amplifies the driver signal to an output power level. IC3 is a power module which has amplification output capabilities of about 35 W with 300 mW input. The output from IC3 (pin 4) is passed through the antenna switching circuit (D10) and is then applied to the antenna connector via the low-pass filter.
4-2 TRANSMITTER CIRCUITS
4-2-1 MICROPHONE AMPLIFIER CIRCUIT (MAIN UNIT)
The microphone amplifier circuit amplifies audio signals with +6 dB/octave pre-emphasis from the microphone to a level needed at the modulation circuit. The AF signals from the microphone are amplified at the microphone amplifier (IC11A) via the analog switch (IC12B, pins 6, 5). A capacitor (C159) and resistor (R121) are connected to the amplifier to obtain the pre-emphasis characteristics.
4-2-5 APC CIRCUIT (MAIN UNIT)
The APC circuit stabilizes transmit output power. The RF output signal from the power amplifier (IC3) is detected at the power detector circuit (D8, D9, L12) and is then applied to one of the differential amplifier inputs (Q15, pin 5) via the High/Low control circuit (R71, Q16). The applied voltage controls the differential amplifier output (Q15, pin 2) and the bias voltage control (Q12). Thus the APC circuit maintains a constant output power.
AF AMPLIFIER CIRCUIT
External SP Vcc PWR AMP IC9 (VR-A board) AF MUTE HPF C140 "DET" signal from the FM IF IC (IC1, pin 9) de-emphasis circuit R101
Internal SP (LOGIC board)
4-3 PLL CIRCUITS
The PLL circuit provides stable oscillation of the transmit frequency and receive 1st LO frequency. The PLL circuit compares the phase of the divided VCO frequency to the reference frequency. The PLL output frequency is controlled by a crystal oscillator and the divided ratio of the programmable divider. IC2 on the MAIN unit is a dual PLL IC which controls both VCO circuits for Tx and Rx, and contains a prescaler, programmable counter, programmable divider, phase detector, charge pump, etc.
4-3-2 TX AND RX LOOP (MAIN UNIT)
The generated signal at the VCO (Q4, Q5, Q6, D1D4) enters the PLL IC (IC2, 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 (R29R31, R41, C41, C42, C50, C51), and is then applied to varactor diodes (D3, D4) of the VCO to stabilize the oscillated frequency. The lock voltage from the loop filter is amplified at the buffer amplifier (Q7) and then applied to the RF circuit.
The PLL circuit, using a one chip PLL IC (MAIN unit; IC2), directly generates the transmit frequency and receive 1st IF frequency with VCOs. The PLL sets the divided ratio based on serial data from the CPU on the LOGIC unit and compares the phases of VCO signals with the reference oscillator frequency. The PLL IC detects the out-of-step phase and output from pins 8 for Tx and Rx. The reference frequency (21.25 MHz) is oscillated at X2 (MAIN unit).
4-3-4 VCO CIRCUIT (MAIN UNIT)
4-5 LOGIC CIRCUITS (LOGIC BOARD)
CPU IC1 is an 8 bit signal chip micro-computer and contains LCD driver, serial I/O, timer, A/D converter, programmable I/O, ROM and RAM. SYSTEM CLOCK CIRCUIT X1 is a ceramic oscillator and oscillate 9.8304 MHz system clock for the CPU (IC1). RESET CIRCUIT IC6 is a reset IC. When turn power ON, IC6 outputs a reset signal (LOW pulse) to the CPU (IC1, pin 15) via the RES line. LOW BATTERY DETECTOR VCC voltage is divided by R74, R75 and is applied to the low battery detector section in the CPU (IC1, pin 91) via the LBAT line. DIMMER CIRCUIT CPU (IC1), Q2, Q3 and Q4 are dimmer circuit and control the 4 steps the LCD backlight (DS3DS8).
