MM-013994-001, Rev. Ap1 1 SAFETY CONVENTIONS The following conventions are used throughout this manual to alert the user to general safety precautions that must be observed during all phases of operation, service, and repair of this product. Failure to comply with these precautions or with specific warning elsewhere in this manual violates safety standards of design, manufacture, and intended use of the product.
MM-013994-001, Rev. Ap1 2 SAFETY TRAINING INFORMATION The Harris P7300 portable radio generates RF electromagnetic energy during transmit mode. This radio is designed for and classified as “Occupational Use Only,” meaning it must be used only during the course of employment by individuals aware of the hazards and the ways to minimize such hazards. This radio is NOT intended for use by the “General Population” in an uncontrolled environment.
MM-013994-001, Rev. Ap1 • As noted in Table 2-1, ALWAYS keep the device and its antenna AT LEAST 1.1 cm (0.43 inches) from the body and at least 2.5 cm (1.0 inch) from the face when transmitting to ensure FCC RF exposure compliance requirements are not exceeded. However, to provide the best sound quality to the recipients of your transmission, Harris recommends you hold the microphone at least 5 cm (2 inches) from mouth, and slightly off to one side.
MM-013994-001, Rev. Ap1 3 OPERATING TIPS Antenna location and condition are important when operating a portable radio. Operating the radio in low lying areas or terrain, under power lines or bridges, inside of a vehicle or in a metal framed building can severely reduce the range of the unit. Mountains can also reduce the range of the unit. In areas where transmission or reception is poor, some improvement may be obtained by ensuring that the antenna is vertical.
MM-013994-001, Rev. Ap1 3.1.3 3.1.4 Aircraft • Always turn off a portable radio before boarding any aircraft! • Use it on the ground only with crew permission. • DO NOT use while in-flight!! Electric Blasting Caps To prevent accidental detonation of electric blasting caps, DO NOT use two-way radios within 1000 feet of blasting operations. Always obey the "Turn Off Two-Way Radios" signs posted where electric blasting caps are being used. (OSHA Standard: 1926.900) 3.1.
MM-013994-001, Rev. Ap1 4 BATTERIES The P7300 series portable radios use rechargeable, recyclable Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH), or Lithium Ion (Li Ion) batteries. Please read carefully, the battery information provided, to maximize the useful life of each type of battery. Do not disassemble or modify Lithium Ion battery packs. The Lithium Ion battery packs are equipped with built-in safety and protection features.
MM-013994-001, Rev. Ap1 Always use Harris authorized chargers and conditioners. Use of unauthorized chargers and conditioners may void the warranty. CAUTION 4.1.3 Additional Information For more information regarding the proper care of portable radio batteries or establishing a battery maintenance program, refer to ECR-7367 which may be ordered by calling toll free 1-800-368-3277, then select option 7. 4.2 CHARGING BATTERY PACKS Battery chargers are available from Harris with nominal charge times.
MM-013994-001, Rev. Ap1 Do not leave any Harris rechargeable batteries in a charger for more than a few days. 4.4 CHANGING THE BATTERY PACK 4.4.1 Removing the Battery Pack Make sure the power to the radio is turned OFF. CAUTION Although the P7300 has been designed to tolerate changing the battery pack without turning power off, Harris recommends turning the radio off before changing battery packs to ensure safety and best operation. 1.
MM-013994-001, Rev. Ap1 4.4.2 Attaching the Battery Pack Make sure the power to the radio is turned OFF. 1. Align the tabs at each side on the bottom of the battery pack with the slots at the bottom of the battery cavity . 2. Push the top of the battery pack down until the latches click to attach the battery to the radio. 3. Tug gently to verify that the latches are secure and the battery pack is properly attached to the radio. Figure 4-2: Attaching the Battery Pack 4.
