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.

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.

Radio features

The SP-400 series is a programmable, synthesized radio with

the following features:

5Easy to use – only five controls access all the

transceiver’s functions.

5Up to sixteen channel capacity – simple and reliable

knob selection.

5Programmable transmit power – select the transmit

power to maximize range or battery life. 1 or 5 watts (4

watts UHF) programmable per channel.

5Channel 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.

5CTCSS/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.

52-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.

5VOX (voice operated transmit) – allows hands-free

operation using an optional headset/microphone.

5Voice 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.

52-tone or sequential tone selective call – for more

advanced radio network management. Allows individual

or group calls to users in a radio network.

5Emergency selective call – can be sent to alert other

users of an emergency situation with an activation

protected against accidental switching.

5Busy channel lockout – prevents transmission when

the channel is busy. Programmable override function will

allow transmission during repeater hangtime.

5Transmit time-out timer – ensures continuous

transmissions are limited to the programmed time. A

penalty timer is also programmable.

5Battery save mode – may be programmed to extend

battery life.

5Wide range of optional accessories –provide

additional flexibility of use.

These transceivers are compliant with ETS 300 086, IEC529
