*SAFETY ITEMS*DO NOT...operate the portable radio near or in an area where

blasting is taking place. Anyone using radio controlled explosives must post signs. If you see a caution sign about blasting in the area, you must turn your radio off. This applies to any radio equipment capable of transmitting: phones, CB’s, etc.

DO NOT...operate the portable radio in an explosive atmosphere. The radio is an electrical device with switches that can cause an explosion in an explosive atmosphere. If you can operate your vehicle or any power tools, it is safe to use the radio.

ECP3127B page 3

*SAFETY ITEMS*To ensure that user exposure to RF electromagnetic energy is

within the FCC allowable limits for occupational use, always adhere to the following guidelines:

DO NOT operate the radio without a proper antenna.

DO NOT transmit for more than 50% of the total radio use.

Always use only Tyco Electronics authorized accessories.

Always keep the antenna at least 5cm (2 inches) away from the body while transmitting.

ECP3127B page 4

Operating Rules and RegulationsThe Federal Communications Commission sets all rules for two-

way radio use. The user of two-way radio equipment should be familiar with these basic rule requirements.

• It is a violation of FCC rules to interrupt any distress or emergency message.

• Any use of profane or obscene language is prohibited.

• It is against the law to send false call letters or a false distress or emergency message.

• All messages must be brief and limited to the business need.

• It is a violation of FCC rules to send personal messages, unless in an emergency.

• The FCC requires that radio systems be identified by use of the assigned Call Letters. The radio system does this automatically.

Project 25 (P25)

Project 25 is a public safety communications standard dedicated to ensuring interoperability in communications. It is designed to ensure fast and secure communications between local, state and federal agencies when protecting the public's welfare.

The Project 25 standard organization is comprised of the Association of Public Safety Communications Officials (APCO), the National Association of State Telecommunications Directors (NASTD) and the U.S. Federal Government.

The Federal Government through the National Telecommunications and Information Administration (NTIA) has dictated that all new and existing federal communications systems will be P25 compliant.

P25 is an all digital voice system that can be trunking or conventional non-trunking.

Why Trunking?Trunking:

–Improves spectral efficiency

–Relieves the user from managing the channel

–Encourages cross agency / shared communications

–Establishes communications privacy

–Encourages private communications

–Discourages eavesdropping by scanners

–Establishes “queuing” rather than “waiting”

–Enables priority use during busy times

ECP3127B page 8

P25 Trunking System Features

• Digital Control Channel

• Multiple Working Channels

• < 0.5 Second Access

• Group & Individual Voice Calls

• Unit ID for each radio

• Late / Delayed Entry

• Emergency Calls

• Queuing with Priority

• Unit Enable / Disable

• Wide Area Coverage

ECP3127B page 9

???

How Far Does it Cover ?

Many factors affect range:

– Site Location

– Urban Clutter

– Reflections / Multipath

– Ducting over Water

– Heavy vegetation

– Weather

– Frequency

ECP3127B page 10

Extending CoverageTechnology exists to extent the coverage of the radio and communication system.

You have no indication that the technology is occurring other than better coverage.

Some indications are the individual radios transmit and inform the P25 system of their status:

– Each time the Radio is powered up.

– Each time a Group selection is made.

– Each time a the radio moves to a different RF site.

ECP3127B page 11
