Midland 220 is the brand new Multi Standard CB transceiver, essential in its functionalities but with
advanced performances, such as the ESP2 (noise killing device).
Midland 220 is a very practical radio, very easy to install even into the DIN housing of the vehicles
(usually suitable for car radios).
As required by this kind of installation the speaker is on the front panel to guarantee a high-quality
acoustic level.
MIDLAND 220 is supplied with a microphone with up/down buttons, mounting bracket and
adaptor for DIN mounting.

A) Selected channel (from 1 up 40) or operative frequency
B) FREQ button activated
C) ESP: reducing noise device activated
D) EMG: indicates channel being used or when the emergency channels are activated
E) M1 – M4: memory channel indicator
F) Indicates the frequency band selected
G) Appears when the radio transmits in low power (this condition happens only in some
frequency bands – see the chart at the end of the manual)
H) RX/TX: reception (RX) / transmission (TX) indicator.
I) AM/FM mode.
J) Received signal strength and transmitted signal power.
3. Button for changing colour: by pushing a pointed object into the hole, you can change the
backlight colour of the display. You can choose amongst the following colours: white, yellow,
violet, red, light blue, green, blue or no colour.
4. “AM/FM”(LCR) button: To select AM or FM mode. If you select a frequency band operating in
FM mode only, this button enables the LCR function (Last Channel Recall).
5. “Squelch” Control: For the maximum receiver sensitivity, the control must be regulated exactly
where the receiver background noise disappears.

6. “ON/OFF Volume” Control. In “OFF” position your transceiver is OFF. “VOLUME” position: by
turning this knob, you set the audio level.
7. Microphone jack: Insert the mic connector into this jack.
8. EMG button: Emergency channel. By pressing it, the unit will be automatically positioned on
CH 9/19 (emergency channels). The display will show “EMG”. It will not be possible to accidentally change the channel.
9. “Mic (Microphone) Gain Control”: in TX mode, it controls the microphone amplification.
The best results are obtained by getting the best modulation: use the mike by trying to find the
optimal amplification level and distance from your mouth.
10.“RF” (Radio Frequency) Gain Control: it controls the reception sensitivity. To increase the
sensitivity, simply turn it clockwise. Sensitivity decreases turning it counterclockwise. Low sensitivity is useful in case of very strong signals.
11. “N.K./ESP” button
Pressing this switch, you activate the noise killing device. Receiver noise and interference can
now be largely eliminated by the ESP2 system.
12.FREQ button
With this button, you can:
• visualize the operative frequency (if you keep pressing the button for 3 seconds approx.), or
the channel in use;
• activate the second functions of the “M” (M1/M4) buttons.
M1 / M4:
MIDLAND 220 has the possibility to store and to recall, when necessary, 2 channels previously
memorized.
To memorize one channel, follow the procedure herebelow:
A) Select the channel with the appropriate selector or the “UP/DN” buttons on the microphone;
B) Push the “FREQ” button: the display will show “F”;
C) Keep pressed the “AM/FM/LCR” button for 3 seconds: you will hear a “BIP” and the display
will show “M1”.
To memorize the other channels, repeat these steps and press “EMG”.
To recall a channel previously stored, push the “FREQ” switch and then “AM/FM/LCR” (M4) or
“EMG” (M1).

Safety and convenience are the primary considerations for mounting any piece of mobile equipment.
All controls must be readily available to the operator without interfering with the movements
necessary for safe operation of the vehicle. Interference from the connecting cables may contribute
to the loss of control of the vehicle.
Set the proper position in the car to install the transceiver using the supplied supporting bracket or
eventually the DIN mounting bracket.
Tighten the retaining screws. The mounting bracket must be close to metallic parts.
POWER SUPPLY
Be sure the transceiver is OFF. In the direct-voltage power supply, it is very important to observe
the polarity even if the unit is protected against the accidental inversion:
Red = positive pole (+)
Black = negative pole (-)
The same colours are present on the battery and in the fuse box of the car. Correctly connect the
cable terminal to the battery.
INSTALLING AN ANTENNA
1. Place the antenna as high as possible
2. The longer the antenna is, the better will be the performance
3. If possible, mount the antenna in the centre of whatever surface you choose
4. Keep antenna cable away from noise sources, such as the ignition switch, gauges,etc.
5. Make sure you have a solid metal-to-metal ground connection.
6. Prevent cable damage during antenna installation.
WARNING: To avoid damage, never operate your CB radio without connecting a proper antenna.
A periodical control of the cable and of the S.W.R. is recommended.
HOW TO OPERATE YOUR TRANSCEIVER
1. Screw the microphone plug into the microphone jack.
2. Make sure your antenna is connected to the antenna connector.
3. Make sure the SQUELCH control is turned fully conterclockwise.
4. Turn on the unit and adjust the volume control.
5. Select your desired channel.
6. To transmit, press the PTT button and speak in a normal tone of voice.
7. 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.
Procedure:
1. Switch off the unit.
2. Turn it on while pushing the “N.K./ESP” button.
3. Select the desired frequency band by pushing the UP / DOWN buttons (see the chart here
below).
Wait for 5 seconds or switch off and then on the radio.
NOTE1: In the UKE or UKC frequency bands, you can select directly the other band by pushing the
13
ENGLISH
INSTALLATION
“AM/FM/LCR” button for 3 seconds.
NOTE2: If you select a frequency band which operates in FM mode only, the “AM/FM/LCR” control
enables the LCR function (last channel recall).
