    FCC RF EXPOSURE COMPLIANCE REQUIREMENTS 
    FOR OCCUPATIONAL USE ONLY 
    The Federal Communications Commission (FCC), within 
    its action in General Docket 93-62, November 7, 1997, 
    has adopted a safety standard for human exposure to 
    Radio Frequency (RF) electromagnetic energy emitted 
    by FCC regulated equipment. Midland Radio Corporation 
    subscribes to the same safety standard for the use of its 
    products. Proper operation of this radio will result in user 
    exposure far below the Occupational Safety and Health 
    Act (OSHA) and FCC limits. 
     DO NOT transmit for more than 50% of total use 
    time (50% duty cycle). Transmitting more than 
    50% of the time can cause FCC RF exposure 
    compliance requirements to be exceeded. 
     This radio is NOT approved for use by the 
    general population in an uncontrolled 
    environment. This radio is restricted to 
    occupational use, work related operations only, 
    where the radio operator must have the 
    knowledge to control the user’s exposure 
    conditions for satisfying the higher exposure 
    limit allowed for occupational use. 
     When transmitting, hold the radio in a vertical 
    position with its microphone 2 inches (5 cm) 
    away from your mouth. The radio is transmitting 
    when the red LED on the front of the radio is 
    illuminated. You can cause the radio to transmit 
    by pressing the PTT button on the radio. DO NOT 
    transmit while the radio is attached to your belt. 
     These are required operating conditions for 
    meeting FCC RF exposure compliance. Failure to 
    observe these restrictions means violation.

    Disclaimer 
    Midland Radio Corporation is committed to continuous quality 
    improvements, for this reason specifications may change without 
    prior notice. 
    Every effort has been made to ensure that the information in this 
    document is complete, accurate, and up-to-date. Midland 
    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 unauthorized 
    people will not affect the transceiver’s performance or functions. 
    Safety 
    Your SP-400 series portable 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 injury to yourself or 
    damage to 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 attach or 
    remove the antenna. 
     Do not hold the radio with the antenna very close to, 
    or touching the body, while transmitting. The radio 
    will perform best if the microphone is 2-4 inches away 
    from the mouth and the radio is vertical. 
     Be sure the PTT button is not pressed when you do 
    not need to transmit.

     SP-400 Series User’s Guide 
     Do not operate the radio near unshielded electrical 
    blasting caps or in an explosive atmosphere. 
     Do not transmit without the antenna attached to the 
    radio. Though designed for protection against damage, 
    damage to the transmitter may occur. 
     Respect the environmental conditions. The radio is 
    designed to operate in harsh environments, but avoiding 
    extended or unnecessary exposure will prolong the 
    service life. 
     Never attempt to disassemble or service the radio 
    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 or 
    communications coordinator for assistance. 
     Use only recommended accessories. Use of incorrect 
    accessories could seriously damage your handheld 
    transceiver. 
     Do not use your radio near water, or spill liquid of 
    any kind into it. If the transceiver gets wet immediately 
    dry it with a soft, clean cloth. 
     Switch the radio off before you clean it. Follow the 
    instructions in the “Care and maintenance” section. 
     Handle the battery properly. Follow the instructions in 
    the “Care and maintenance” section. 
     Make sure that your AC power source matches the 
    rating of the supplied battery charger AC adapter. 
     The above warning list is not intended to include all 
    hazards that may be encountered when using this radio.

    SP-400 Series User’s Guide  
    Introduction 
    Congratulations! By choosing the Midland SP-400 series, you 
    have selected a professional grade portable radio. Its rugged 
    design will provide years of reliable service and its sophisticated 
    software allows many customizable options. 
    Radio models 
    There are four models in the SP-400 series portable radio line. 
    The models differ only by band of operation and channel 
    capacity. 
    SP-410 – 4 channel VHF, 148-174 MHz. 
    SP-420 – 4 channel UHF, 440-470 MHz. 
    SP-430 – 16 channel VHF, 148-174 MHz. 
    SP-440 – 16 channel UHF, 440-470 MHz. 
    Radio features 
    The SP-400 series is a programmable, synthesized radio with 
    the following features: 
    5 Easy to use – only five controls access all the 
    transceiver’s functions. 
    5 Up to sixteen channel capacity – simple and reliable 
    knob selection. 
    5 Programmable transmit power – select the transmit 
    power to maximize range or battery life. 1 or 5 watts (4 
    watts UHF) programmable per channel. 
    5 Channel scanning – flexible scan programming allows 
    the radio to search for signals on programmed channels. 
    Priority scan, priority transmit and priority lookback are 
    all programmable selections. Scan talkback and 
    nuisance delete functions are available. 
    5 CTCSS/DCS encode and decode– blocks 
    conversations sharing the same frequency that are not 
    intended for you. Allows access to your radio repeaters.

     SP-400 Series User’s Guide 
    47 CTCSS tones and 104 DCS codes programmable per 
    channel. 
    5 2-tone decode – your radio may be programmed to 
    respond only when paged with a two-tone sequence. 
    Two sequences selectable per channel and up to 15 
    different sequences programmable per radio. 
    5 VOX (voice operated transmit) – allows hands-free 
    operation using an optional headset/microphone. 
    5 Voice inversion scrambler – for secure 
    communications. Radio communications are encoded 
    and decoded, when activated, to make the conversation 
    unintelligible to third parties listening on your frequency. 
    5 2-tone or sequential tone selective call – for more 
    advanced radio network management. Allows individual 
    or group calls to users in a radio network. 
    5 Emergency selective call – can be sent to alert other 
    users of an emergency situation with an activation 
    protected against accidental switching. 
    5 Busy channel lockout – prevents transmission when 
    the channel is busy. Programmable override function will 
    allow transmission during repeater hangtime. 
    5 Transmit time-out timer – ensures continuous 
    transmissions are limited to the programmed time. A 
    penalty timer is also programmable. 
    5 Battery save mode – may be programmed to extend 
    battery life. 
    5 Wide range of optional accessories – provide 
    additional flexibility of use. 
    These transceivers are compliant with ETS 300 086, IEC529 
    level IP54 and MIL STD 810E.
