USER MANUAL 203 MIDLAND

MIDLAND 203 Midland 203 is the brand new Multi Standard CB transceiver, essential in its functionalities but with advanced performances: Phase Locked Loop circuitry gives precise frequency control and stability over all channels (pinpoint channel tuning accuracy with separate scan up and down controls); the ceramic lters give superior selectivity and freedom from adjacent channel interfe- rence. Midland 203 is supplied with a microphone, mounting bracket and power supply cable.

FUNCTIONS AND LOCATION OF THE CONTROLS

1. Channel UP/DOWN switch: it allows the manual channel selection.2. “AM/FM” switch: To select AM or FM modulation. 3. “ON/OFF Volume” knob: “OFF” position: transceiver turned off. “VOLUME” position: to set the audio level 4. “Squelch” knob: to eliminate “chopping” signals during message recep-tion.5. Microphone jack: jack for the mic connector 6. CH 9-19 switch: to tun immediately on priority channels 9 or 19.7. Channel display: shows the number of the channel in use.8. RX/TX led: shows the operative mode: Green: RX Red: TX

INSTALLATION An extremely important requirement is the ease of installation and removal for those occasions when you might want to remove the unit for service and maintenance. The most common mounting position for a transceiver is under the dashboard directly over the drive shaft hump. Do not mount the transceiver in the path of the heater or air conditioning. Take your time and plan your installation carefully. When you have determi- ned the best location for mounting, use the mounting bracket as a template to mark mounting holes. Take care when you drill the holes that you do not drill into wiring, trim or other accessories. Mount in position with bolts, lock washers and nuts or self-threading screws. Insert the power cable with lighter plug into the vehicle’s cigarette lighter cord. Before operating, you must install and connect your antenna system. The lead from the antenna you’ve installed should be connected to the antenna coaxial connector. If you are using an external speaker, connect it to the EXT- SPKR jack.

INSTALLING AN ANTENNA

A mobile antenna system is not limited to the antenna only. The transmission line, as well as the vehicle, are important factors in the total antenna system. Therefore, you must use the correct type of transmission line and mount the antenna securely in a position that will give you optimal results. Use coaxial cable with an impedance of 50 Ohms. Generally speaking, you should keep the length of the transmission line to a minimum. The above discussion is as important for reception as it is for the transmis- sion. If a mismatch exists between the antenna and the receiver, the excellent sensitivity and signal-to-noise radio of the receiver circuit will be defeated. Useful information

1. Place the antenna as high as possible

2. The longer the antenna is, the better will be the performance

3. Mount the antenna and keep antenna cable away from noise sources,

such as the ignition switch, gauges, etc.

4. Make sure you have a solid metal-to-metal ground connection.

5. Prevent cable damage during antenna installation.

There are many types of mobile CB antennas: a full quarter-wave length whip, a center loaded whip, top loaded whip and the base loaded type. For a greater efciency it is recommended 2.5 m long, full quarter-wave whip. 9CH19

Antenna length is directly related to efciency. A vertically polarized whip antenna is best suited for mobile service. It is omni- directional. Roof mount is the best ever as in this position the antenna radiates equally in all directions.

WARNING: To avoid damage, never operate your CB radio without connect-

ing a proper antenna. A periodical control of the cable and of the S.W.R. is recommended.

HOW TO OPERATE YOUR MIDLAND 203

After have installed and cabled your CB transceiver, follow these steps to operate with your device:

1. Screw the microphone plug into the microphone jack and check that the

unit is properly connected

2. Make sure your antenna is connected to the antenna connector.

3. Make sure the SQUELCH control is turned fully counter clockwise.

4. Select AM or FM mode.

5. Turn on the unit and select the frequency band to use

6. Adjust the volume to a suitable listening level

7. Select your desired channel.

8. Adjust Squelch to cut out annoying background noise when no signal is

9. To transmit, press the PTT button and speak in a normal tone of voice.

10. To receive, release the PTT button.

FREQUENCY BAND SELECTION

The frequency bands must be chosen according to the country where you are going to operate. Your Midland 203 can be set on 4 different frequency bands: IT(it): 40CH 26.965 MHz – 27.405 MHz 4W AM/FM EU(EU): 40CH 26.965 MHz – 27.405 MHz 1W AM/4W FM PL(PL): 40CH 26.960 MHz – 27.400 MHz 4W AM/FM D3(d3): 80CH from CH1 to CH40 26.965MHz – 27.405 MHz 1W AM/4W FM from CH41 to CH80 26.565MHz – 26.955 MHz 4W FM Procedure:

1. Switch off the unit.

2. Turn the device on and contemporary keep pressed the UP/DOWN buttons.

3. Select the desired frequency band by pushing the UP/DOWN buttons

4. To conrm the selection, press the PTT button or wait for 5 seconds.

Note: Once have set the frequency band, every time you turn on the radio, the display will show for 1 second the frequency band in use. To change the frequency band, follow the steps upon described. SQUELCH The Squelch function cuts out annoying background noise when no signal is being received. To do this, set the Channel Selector to a channel where no signals are pre- sent or wait until signals cease on your channel. Then, rotate the Squelch control in a clockwise direction to the point where the background noise just stops. Now, when a signal is present, you will hear it, but will not be disturbed by noise on the channel between signals. When properly set, the Squelch keeps the receiver “dead” until a signal co- mes in on that channel. However, do not set the Squelch too high, otherwise weak signals will not be able to open the Squelch circuit. To receive very weak signals, it is better to leave Squelch set to the minimum position by rotating the control maximum counterclockwise. EMERGENCY CHANNELS (CH 9-19) Midland 203 is equipped with a switch that allows to be immediately set on the Priority cannels 9 and 19. CH 9 is for Emergency communications, while CH 19 is used for asking road condition information. The centre position of the switch is for tuning on the latest selected channel.

REMOTE SPEAKER OPERATION

A 4 Ohm speaker, rated at 3-10 watts, should be used for this function. Plug the speaker into the EXT SPKR jack at the rear of the transceiver. When the external speaker is plugged in, the internal speaker is disconnected.8 WARRANTY Midland will repair or replace, at its option without charge, any Midland 203 transceiver which fails due to a defect in material or workmanship within TWO Years following the initial consumer purchase.
