Training Session Notes

2. *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.

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.

4. Operating Rules and Regulations
The 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.
The federal government communications is administered by the National Telecommunications and Information Administration (NTIA), but operation is still compliant to FCC rules.

5. 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.

7. 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

Many factors affect range:
Site Location
Urban Clutter
Reflections / Multipath
Ducting over Water
Heavy vegetation
Weather
Frequency

10. Extending Coverage
Technology 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.
