Introduction
Congratulations. 75-440 is an advanced GMRS (General Mobile Radio Service) Professional Radio. Its rugged design allows it to be your reliable partner even during hard working days. Its LCD as well as user friendly controls make the 75-440 easy to use.
To extend the flexibility of the radio, a “VOX” (Voice Operated Transmit) function has been added which allows switching the transmission just by talking in full hands free condition (with optional headset).
Transceiver’s specifications provided in 75-440 are compliant with EIA/TIA 603 and ETS 300 086, The 75­440 top level design and resistance are compliant with IEC529 level IP54 and MIL STD 810 C,D,E.
Midland Radio is committed to continuous quality improvements, for this reason specifications may vary without prior notice.
Warning notes
Every effort has been made to ensure that the information in this document is complete, accurate, and up­to-date. Midland Radio assumes no responsibility for the results of errors beyond its control. The manufacturer of this equipment also cannot guarantee that changes in the equipment made by non authorized people will not affect the applicability of the information in it.
FCC Licensing Information
This Midland model 75-440 radio operates on GMRS frequencies which require a license from the Federal Communications Commission (FCC) for business, personal, and recreational use. A GMRS license held by an individual may be shared by immediate family members.
To obtain forms, call the FCC forms hotline at: 1-800-418-3676 or go to http://www.fcc.gov. Please request forms
605
and 159 which include all necessary forms and instructions.
For questions concerning licensing, contact the FCC at 1-888-CALL-FCC (1-888-225-5322), or go to
http://wireless.fcc.gov/services/personal/generalmobile .
Safety
Your 75-440 handheld transceiver has been carefully designed to give you years of safe, reliable performance. As with all electrical equipment, however, there are a few basic precautions you should take to avoid hurting yourself or damaging the radio:
• Read the instructions in this handbook carefully. Be sure to save it for future reference.
• Read and follow all warning and instruction labels on the radio itself.
• Do not carry the transceiver by the antenna. This may damage the antenna or antenna terminal.
Grasp it by its base (not the tip!) when you need to place or remove it.
• Do not keep the radio with the antenna very close to, or touching exposed parts of the body, while transmitting. The radio will perform best if the microphone is 5-10 cm away from the mouth and the radio is vertical.

• Be sure the “PTT” key is not pressed when you do not need to transmit.
• Do not operate the radio near unshielded electrical blasting caps or in an explosive atmosphere.
• Do not transmit without the antenna fitted on the radio. Though it is provided with a protection, it
may damage the TX output final stage.
• Respect the environment conditions. The radio is designed to be used in heavy environments, however avoid exposing it to extremely hot or cold temperature (out of the range between –30 to +60°C). Do not expose the transceiver to excessive vibrations as well as dusty or rainy places.
• Never try to disassemble or service the radio by yourself (aside from the routine maintenance described in this handbook). It will immediately void the warranty and you may cause damage requiring extensive repair work. Always contact your local dealer for assistance.
• Use only authorized accessories. Non original ones could seriously damage your handheld transceiver.
• Do Not spill liquid of any kind into your radio. If the transceiver gets wet, immediately dry it by a soft and clean cloth.
• Switch the radio off before you clean it. Strictly follow the directions described in the paragraph “Care and maintenance”.
• Handle the battery properly. Strictly follow the directions reported in “Care and maintenance”.
• Be certain that your power source matches the rating listed for the supplied battery charger (AC
adapter). If you are not sure, check with your dealer.
• To avoid damaging the power cable of the battery charger, do not put anything on it or place it where it will be walked on.
This product complies with the requirements of the Council Directives 89/336/EEC and 73/23/EEC on the approximation of the laws of the member states relating to electromagnetic compatibility and low voltage.
WARNING
Your wireless hand-held portable transceiver contains a low power transmitter. When the Push-to-Talk (PTT) button is pressed it sends out radio frequency (RF) signals. The device is authorized to operate at a duty factor not to exceed 50%. In August 1996, the Federal Communications Commission (FCC) adopted RF exposure guidelines with safety levels for hand-held wireless devices.
To maintain compliance with the FCC's RF exposure guidelins, this transmitter and it’s antenna must maintaina a separation distance of least 2 inches (5 centimeters) from your face. Speak in a normal voice, with the antenna pointed up and away from the face at the required separation distance. The beltclip is for storage purposes only. DO NOT TRANSMIT WHILE USING THE BELT CLIP. To transmit, hold the device away from your body and ensure the antenna is at least least 2 inches (5 centimeters) from your body when transmitting.
