Consult the dealer or an experienced radio/TV technician for help
IMPORTANT NOTICE, FCC LICENSE REQUIRED
The DBR2500 operates within Amateur (HAM) frequencies which require an FCC (Federal Communications Commission) license� You must be licensed prior transmitting on this radio� Serious penalties could result from unlicensed use of HAM channels, in violation of FCC rules, as stipulated in the Communications Act’s Sections 501 and 502 (amended)�
You will be issued a call sign by the FCC which should be used for station identication when
operating the radio on Amatuer (HAM) channels� You should also cooperate by engaging in permissible transmissions only, avoiding channel interference with other HAM users, and being prudent with the length of your transmission time� To obtain a license or ask questions about the application, contact the FCC at 1-888-CALL FCC or go to the FCC’s website: http://www�fcc�gov and request form 605�
Exposure To Radio Frequency Energy
Your Midland radio is designed to comply with the following national and international standards and guidelines regarding exposure of human beings to radio frequency electromagnetic energy�
United States Federal Communications Commission, Code of Federal Regulations: 47 CFR part 2 sub-part J
American National Standards Institute (ANSI)/Institute of Electrical & Electronics Engineers (IEEE) C95� 1-1992
Institute of Electrical and Electronics Engineers (IEEE) C95� 1-1999 Edition
National Council on Radiation Protection and Measurements (NCRP) of the United
States, Report 86, 1986
International Commission on Non-lonizing Radiation Protection (ICNIRP) 1998
To control your exposure and ensure compliance with the general population or
uncontrolled environment exposure limits, transmit no more than 50% of the time� The radio generates measurable RF energy exposure only when transmitting�

INSTALLING YOUR RADIO
Preparation for Installation
This transceiver may be installed in any 12-volt negative ground-system car or truck� Most current U�S� and foreign vehicles use a negative system, but some older models and some newer large trucks may have a positive ground�
Check the requirements for your vehicle before you begin installation�
Generally, you have a negative-ground system if the negative ( - ) battery terminal is connected to the engine block� Contact your dealer in the event you are unable to determine your vehicle’s polarity system�
Mobile Installation
To install the tranceiver, select a safe, convenient location inside your vehicle that minimizes danger to your passengers and yourself while the vehicle is in motion� Consider installing the unit at an appropriate position so that knees or legs will not strike it during sudden braking of your vehicle� Try to select a well ventilated location that is shielded from direct sunlight� Also take into consideration the routing and length of the lead wires and cables to the power source, and antenna�
1� Install the Mounting bracket in the vehicle using the supplied selftapping screws (2pcs) and
at washers (2pcs).
2� Position the tranceiver, then insert and tighten the supplied hexagon screws�
-Double check that all screws are tightened to prevent vehicle vibration from loosening the bracket or DBR2500�

DC POWER CABLE CONNECTION
Locate the power input connector as close to the DBR2500 as possible.
Mobile Operation
The vehicle battery must have a nominal rating of 12V� Never connect the tranceiver to a 24V
battery. Be sure to use a 12V battery that has su󰀩cient current capacity. If the current to the tranceiver is insu󰀩cient, the display may darken during transmission, or transmitting power may
be dramatically reduced�
1� Route the DC power cable supplied with the radio directly to the vehicle’s battery terminals
using the shortest path from the DBR2500�
-We recommend that you do not use the cigarette lighter socket, as some cigarette lighter
sockets introduce an unacceptable voltage drop�
- The entire length of the cable must be insulated so that it is protected from heat,
moisture, and engine secondary (high voltage) ignition system and cables�
2� After installing the DC power cable, to avoid the risk of damage, please use heat-resistant
tape to tie together the DC power cable with the fuse box� Be sure to reinforce the entire
power cable with heat resistant tape�
3� In order to avoid the risk of a short circuit, please disconnect the connection with the
negative (-) battery terminal, then connect to the radio�
4.Conrm the correct polarity of the connections, then attach the power cable to the
battery terminals; red connects to the positive (+) terminal and black connects to the
negative (-) terminal�
- Use the full length of the cable without cutting o󰀨 excess even if the cable is longer
than required� In particular, never remove the fuse holders from the cable�
Red

5� Reconnect any wiring removed from the negative terminal�
6� Connect the DC power cable to the DBR2500’s power supply connector
- Press the connectors rmly together until the locking tab clicks.

Fixed Station Operation
In order to use this DBR2500 for xed station operation, you will need a separate 13.8V DC
power supply (not included)�
The recommended current capacity of your power supply is 12A
1�Connect the DC power cable to the regulated DC power supply and ensure that the
polarities are correct� (Red: positive, Black: negative)
- Do not directly connect the DBR2500 to an AC outlet
- Use the supplied DC power cable to connect the DBR2500 to a regulated power supply
- Do not substitute a cable with smaller gauge wires
2�Connect the DBR2500’s DC power connector to the connector on the DC power cable�
- Press the connectors rmly together until the locking tab clicks.
Before connecting the DC power to the DBR2500, be sure to switch the transeiver and the DC power supply to OFF. Do not plug the DC power supply into an AC outlet until you make all connections.
Replacing Fuses
If a fuse blows, determine the cause, then correct the problem� After the problem is resolved, replace the fuse� If newly installed fuses continue to blow, disconnect the power cable and contact Midland Radio Corporation for assistance�

Only use fuses of the specied type and rating, failure to do so could cause damage to the
DBR2500�
If you use the transeiver for a long period of time when the vehicle battery is not fully charged or when the engine is OFF, the battery may discharge, and may not have
sucient power to start the vehicle. Avoid using the transceiver in these conditions.
INSTALLING THE ANTENNA (Sold Separately)
Before operating, install an e󰀩cient, well-tuned antenna. The success of your radio will depend largely on the type of antenna and its correct installation. Use a 50Ω impedance antenna and low-loss coaxial feed-line that has a characteristic impedance of 50Ω, to match the DBR2500
input impedance� Coupling the antenna to the DBR2500 via feed-lines having an impedance
other than 50Ω reduces the e󰀩ciency of the antenna system and can cause interference to
nearby broadcast television receivers, radio receivers, and other electronic equipment�
Transmitting without rst connecting an antenna or other matched load may damage
the DBR2500. Always connect the antenna to the DBR2500 prior to transmitting.
All xed stations should be equipped with a lightning arrester to reduce the risk of re,
electrical shock, and transceiver damage.
Specic installation requirements vary between vehicles. Use the following guidelines to install
the antenna�
*Where you locate your antenna does make a di󰀨erence.*
Some general rules for antenna location that can aid radio performance:
1� Metal surfaces covered by berglass or vinyl may a󰀨ect radio range. Avoid these
locations�
2� Mount the antenna as high on the vehicle as possible� The higher the better�
3� If possible, mount the antenna in the center of whatever surface you choose�
4� Be sure the mounting location is clean and dry before installing the antenna�
5� Route the antenna cable through an accessible entry point, such as a rear door or
trunk opening�
page 10

Model DBR2500
An ideal location of the antenna on a vehicle is shown below:
ACCESSORY CONNECTIONS
External Speaker (Sold Separately)
If you plan to use an external speaker, choose a speaker with an impedance of 8Ω. The
external speaker jack accepts a 3�5mm (1/8”) mono (2-conductor) plug�
External speaker utilizes a double port BTL, please take care when connecting a
speaker to this port. Do not allow the speaker to make contact with a ground, as it could damage the speaker. The image on page 11 shows the incorrect connecting method.
6� When routing the antenna cable inside the vehicle, keep the cable away from noise
sources, such as the ignition system, gauges, etc�
7� Exercise care to prevent cable damage� Make use of existing gaskets, grommets and
weather stripping to protect the cable along its route�
