RF ENERGY EXPOSURE AWARENESS AND CONTROL INFORMATION,

AND OPERATIONAL INSTRUCTIONS FOR FCC OCCUPATIONAL USE

REQUIREMENTS

BEFORE USING YOUR PORTABLE 2-WAY RADIO, READ THIS IMPORTANT RF ENERGY

AWARENESS AND CONTROL INFORMATION AND OPERATIONAL INSTRUCTIONS TO ENSURE

COMPLIANCE WITH THE FCC’S RF EXPOSURE GUIDELINES.

NOTICE: This radio is intended for use in occupational/controlled conditions, where users have

full knowledge of their exposure and can exercise control over their exposure to meet FCC limits.

This radio device is NOT authorized for general population, consumer, or any other use.

This 2-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide

communications between two or more users over a distance. It uses radio frequency (RF) energy or

radio waves to send and receive calls. RF energy is one form of electromagnetic energy; other forms

include electric power, radar, sunlight and x-rays. RF energy, however, should not be confused with these

other forms of electromagnetic energy, which when used improperly can cause biological damage. Very

high levels of x-rays, for example, can damage tissues and genetic material. The energy levels

associated with radio waves from portable 2-way radios, when properly used, are not great enough to

cause biological damage.

Experts in science, engineering, medicine, health and industry work with organizations to develop

standards for exposure to RF energy. These standards provide recommended levels of RF exposure for

both workers and the general public. These recommended RF exposure levels include substantial

margins of protection All 2-way radios marketed in North America are designed, manufactured and tested

to ensure they meet government established RF exposure levels. In addition, manufacturers also

recommend specific operating instructions to users of 2-way radios. These instructions are important

because they inform users about RF energy exposure and provide simple procedures on how to control it.

Please refer to the following WEBSITES for more information on what RF energy exposure is and how to

control your exposure to assure compliance with established RF exposure limits.

FEDERAL COMMUNICATIONS COMMISSION REGULATIONS The FCC rules require manufacturers to comply with the FCC RF energy exposure limits for portable 2way radios before they can be marketed in the U.S. When 2-way radios are used as a consequence of employment, the FCC requires users to be fully aware of and able to control their exposure to meet occupational requirements. Exposure awareness can be facilitated by the use of a product label directing users to specific user awareness information.
PAGE 3
RF EXPOSURE COMPLIANCE AND CONTROL GUIDELINES AND OPERATING INSTRUCTIONS To control your exposure and ensure compliance with the occupational/controlled environment exposure limits always adhere to the following procedures. Guidelines: • Do not remove the RF Exposure Label from the device. • User awareness instructions must accompany device when transferred to other users. • Do not use this device if the operational requirements described herein are not met.

Operation DPH Series VHF Radio DISPLAY OPTIONS Radios with a keypad and display have a slide-out keypad cover. To remove or install the cover, turn off the radio and remove the battery (see Battery Installation, section 2.1.2). Radios with an Alphanumeric Display can be programmed to operate in 7-Segment mode (see Section 2.2.2.9.3).

DPH Series VHF Radio 3.2.2 Operation TRANSMIT Monitor the Channel before transmitting. If in Channel Guard Mode, turn the Monitor-Squelch knob clockwise off the detent position. Press and hold the PTT (Push To Talk) switch. If a Speaker/Microphone is installed, use the Speaker/Microphone's PTT. When the transmitter is on, the red Transmit Indicator glows and the TX annunciator on the LCD appears. Talk in a normal voice with the microphone two to three inches from your mouth.

Operation DPH Series VHF Radio 3.2.3 CHANNEL GUARD OPERATION Channel Guard™ allows one radio or group of radios to be selectively called within a system. In analog mode, Tone (CTCSS) and Digital (CDCSS) Code Guards are used. In digital mode, Network Access Codes (NACs) are used. If the radio has been programmed with Channel Guard, use the following receive and transmit instructions. Channel Guard™ is a trademark of BK Radio. 3.2.3.

Operation DPH Series VHF Radio 3.3 SCAN OPERATION 3.3.1 RECEIVE Scan operates only while the radio is not transmitting. The radio checks for signals on channels in the preset scan list, as well as the channel selected by the channel selector knob. When a signal is detected, scanning stops and the message is received. The received channel is shown in place of the transmit channel. Once the signal ends, the radio continues to monitor the channel for the preset scan delay time before it resumes scanning.

DPH Series VHF Radio 3.3.2 Operation TRANSMIT WITH SCAN ON When Switch B (scan) is up, the radio transmits on the channel selected by the channel selector knob. 1. Select a transmit channel by turning the channel selector knob. 2. Press and hold the PTT switch and talk in a normal voice. When the PTT switch is released, the radio continues to monitor the selected channel for the preset scan delay time before it resumes scanning. 3.3.2.

Operation DPH Series VHF Radio 3.4 PRIORITY SCAN Priority scan enables the radio to receive on any channel while monitoring for a message on the designated priority channel(s). The radio samples each priority channel at a preset rate (.25-2.0 seconds) regardless of activity on any other channel. Priority scan operates only while the radio is not transmitting and can be used in combination with scan operation. When Switch C (priority) is up, the display flashes SCN.
PAGE 11
DPH Series VHF Radio 3.4.2.1 Operation Priority Mode A In Priority Mode A, the priority channel is set by the channel selector knob. Priority Mode A is seldom used by itself because the radio receives and transmits only on the knob-selected channel. When scan and Priority Mode A are enabled, scanning occurs until an active scan channel is found. The radio receives the message while continuing to check the priority (knob-selected) channel. The display shows the scan channel.
PAGE 12
Operation DPH Series VHF Radio 3.4.3 CHANGE THE PRIORITY CHANNEL The fixed priority channel can be permanently set or can be changeable. If the radio has a changeable priority channel, use the following steps to make this change. 1. Slide Switches B (scan) and C (priority) down. CG- A B C SQ OFF-VOL 6 5 4 3 9 10 11 12 13 14 2 1 16 15 7 8 2. Turn the channel selector knob to the channel you want to enter as the new priority channel. 3. Press the [PRI] key.

DPH Series VHF Radio 3.6 Operation GROUP SCAN Channels on each "channel scan list" and groups on the "group scan list" are scanned sequentially. The knob-selected group is always scanned when group scan is enabled, even if that group is not on the group scan list. When group scan is enabled, the following features are disabled: 3.

Operation DPH Series VHF Radio 3.7.5 TIME-OUT TIMER The transmit time-out timer limits the duration of calls and guards against accidentally locking on the transmitter and tying up the radio system. Your dealer can program the duration of the time-out timer (15-225 seconds, or disabled). 3.7.6 BUSY CHANNEL If the radio has been programmed for busy channel operation, it will operate in one of the following three modes: 3.7.6.

DPH Series VHF Radio Operation 3.7.7 ALPHANUMERIC DISPLAY FEATURES DPH Series portable radios are built with alphanumeric displays that can be programmed with the following features. 3.7.7.1 Display Backlighting The DPH radios can be programmed by your dealer to backlight the display when a signal is received or when a key is pressed. The time duration of the backlighting can also be programmed. 3.7.7.
