Din-Bracket
Thanks to this bracket, MIDLAND 88 can be easily installed into the DIN housing
of the vehicles.
Power supply
Be sure the transceiver is off.
On the rear of the radio you will see a bi-color power supply cable with a fuse holder
on the red cable.
This cable is supplied with a connector suitable for the connection to the radio and
vehicle's battery.
It can also be connected to a cigarette lighter cord socket (optional).
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 colors are present on the battery and in the fuse box of the car.
Correctly connect the cable terminal to the battery.
The battery of vehicle must have a nominal capacity of 12 or 24V.
Be sure the battery of the vehicle is able to supply enough power to the radio.
Connect the DC power cable to the regulated DC power supply and ensure that
the polarities are correct.

Replacing fuses
If the fuse blows, try to find a cause before replacing it. If necessary, contact a
service center for assistance.
The fuse on the rear of the radio has a current rating of 5A
Connecting the microphone
Plug-in the supplied microphone to the proper 6 pin connector on the front panel
of the radio. For a better use of the microphone, you can also fix on the vehicle the
supplied mike holder.
Installing an antenna
• Place the antenna as high as possible.
• The longer is the antenna, the better will be the performance.
• If possible, mount the antenna in the centre of the surface.
• Keep the antenna cable away from noise sources, such as the ignition switch,
gauges, etc.
• Make sure you have a solid metal-to-metal ground connection.
• Prevent cable damage during antenna installation.
Attention: To prevent damage, never operate your radio without connecting a proper
antenna. A periodical control of the cable and of the S.W.R. is recommended.
External speakers
If you use external speakers, the impedance must be 8 Ω. The external speaker jack
accepts a 3.5mm mono plug and must be connected to the 'EXP SP' plug on the
rear side of the radio. The same plug will be used when the PA function is activated.
