The Icom IC-V200 VHF FM Transceiver and IC-U200 UHF FM Transceiver are advanced mobile communication devices designed for the Land Mobile market. These transceivers leverage sophisticated computer-based technology and Icom's precision VHF/UHF engineering to offer state-of-the-art design concepts, meeting the demanding needs of Land Mobile users.

Function Description:

The IC-V200 and IC-U200 are two-way radio transceivers, meaning they are capable of both transmitting and receiving radio signals. The IC-V200 operates on VHF (Very High Frequency) bands, while the IC-U200 operates on UHF (Ultra High Frequency) bands. They are designed for mobile use, typically installed in vehicles, to facilitate communication within a defined network or group.

Usage Features:

Installation:

The transceivers are designed for vehicle installation. Users should select a location that can support the device's weight and does not interfere with driving. The mounting bracket is used to mark screw holes, ensuring controls and switches are easily accessible and the display is clearly visible. After drilling, the bracket is mounted, and the screws are tightened. A grounding lead should be connected from the transceiver to the vehicle's chassis ground. A microphone hanger is also provided for convenient storage of the microphone.

Power Requirements:

The transceivers operate on a regulated 13.8V DC, 7A negative ground source. A 12V negative ground system is suitable. It is crucial to note that voltages greater than 16V DC will damage the transceiver, so users must verify the source voltage before connecting the power cable. For vehicles with a 24V battery, direct connection is not possible, and installation information should be sought from an Icom Dealer or Service Center.

Antenna Connection:

The performance of the communication system heavily relies on the antenna. A high-quality 50Ω 5/8 wavelength antenna is recommended for mobile applications. The antenna connects to the transceiver via a PL-259 type connector.

External Speaker:

An optional SP-5 external speaker can be connected to the transceiver, accepting a 2 to 8Ω external speaker. This enhances audio clarity for more reliable communications.

Front Panel Controls:

• POWER/VOLUME Control: This knob serves a dual purpose: turning the transceiver ON and OFF and adjusting the audio output level.
• MONITOR Switch: This switch toggles the monitor function ON and OFF. When activated, it allows listening to a busy channel even if the microphone is in its hanger or if a tone is not programmed for the channel.
• SQUELCH Control: This control sets the squelch threshold level, effectively muting weak incoming signals. Rotating it clockwise increases the threshold, quieting noise until a strong enough signal is received. If unwanted weak signals are still heard, rotating it slightly more clockwise can correct this.
• CHANNEL Select Switch: This rotary switch allows the user to select an operating channel.

Indicators:

• TRANSMIT (TX) Indicator: Lights up when the transceiver is actively transmitting.
• BUSY Indicator: Illuminates when the transceiver is receiving signals or when the squelch is open.
• CALL Indicator: Lights up when a signal is received with the same programmed tone as the one in the transceiver.
• POWER (PWR) Indicator: Lights up when the POWER/VOLUME control is turned ON.

Microphone Connector:

The microphone connects to the transceiver via this port.

Receiving Operations:

1. Receiver Presettings:

   • Push the [MONITOR] switch ON (in position).
   • Rotate the [POWER/VOLUME] control clockwise. The [PWR] indicator will light up.
   • Rotate the [SQUELCH] control fully counterclockwise. The [BUSY] indicator will light up. Adjust the [POWER/VOLUME] control to a comfortable listening level.
   • Rotate the [SQUELCH] control clockwise until the noise is quieted. This sets the threshold for receiving signals. The transceiver will remain silent until a signal opens the squelch circuit. If weak, unwanted signals are received, adjust the [SQUELCH] control slightly more clockwise for correct operation.

2. Normal Receiving:

   • Push the [MONITOR] switch OFF (out position).
   • Select the desired channel using the [CHANNEL] SELECT switch.
   • When a signal is received, the [BUSY] indicator lights up, and sound is emitted from the speaker.
   • To activate the monitor function and listen to a busy channel (even if a tone is not programmed), push the [MONITOR] switch ON (in position).
   • To return to normal operation (listening to stations with the same programmed tone), push the [MONITOR] switch OFF (out position) again.
   • If the microphone is out of its hanger, the monitor function remains ON regardless of the [MONITOR] switch position.
   • The [CALL] indicator lights up when a signal with a programmed tone is received.

Transmitting Operations:

1. Ensure the [BUSY] indicator is OFF before transmitting to avoid interfering with other radio communications.
2. Push the PTT (Push-To-Talk) switch on the microphone to begin transmitting. The [TX] indicator will light up.
3. Speak into the microphone at a normal voice level.
4. Release the PTT switch to return to receiving mode.

Horn-Honk Function:

This feature allows the transceiver to alert the operator via an external signaling device, such as an automobile horn, when a signal with a correct code number is decoded. This is particularly useful when the operator is away from the operating position. To activate this function, an optional UT-32 2-TONE DECODER UNIT or UT-33 2805Hz TONE DECODER UNIT must be installed. The UT-32 offers 100 different selectable tones for interference-free communication. The UT-33 is a sophisticated, high-tech 2805Hz TONE decoder unit with similar functions. An optional UX-11 HORN-HONK DRIVER UNIT is recommended for connecting the transceiver to the signaling device. Installation details for the HORN-HONK FUNCTION should be obtained from an Icom Dealer or Service Center.

Maintenance Features:

The manual does not explicitly detail user-level maintenance features beyond proper installation and power connection. However, the robust design and the recommendation to consult dealers for specific installations (like 24V battery systems or horn-honk function) suggest that complex maintenance or repairs are intended to be handled by authorized service centers.

Optional Products:

• UT-32 2-TONE DECODER UNIT: Designed for interference-free communication with other 2-TONE systems, offering 100 selectable tones. It also enables the horn-honk function when connected to the transceiver's rear panel output.
