PRECAUTIONS
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 LIMITS
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 devise 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, which when used improperly can cause biological damage. Very high levels of x-rays, for example, can damage tissue and genetic material.
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 or 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 instructions on how to control it. Please refer to the following website for more information on what RF energy exposure is and how to control your exposure to assure compliance with established RF exposure limits.
www.fcc.gov/oet/rfsafety/rf-faqs.html www.osha.gov/SLTC/radiofrequencyradiation/index.html
Federal Communications Commission Regulations
The FCC rules require manufacturers to comply with FCC RF energy exposure limits for portable 2-way radios before they can be marketed in the US. 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. Your Datron 2-way radio has a RF exposure product label. Also your Datron user manual includes information and operating instructions required to control your RF exposure to satisfy compliance requirements.
COMPLIANCE WITH RF EXPOSURE STANDARDS
Your Datron 2-way radio is designed and tested to comply with a number of national and international standards and guidelines (listed below) for human exposure to radio frequency electromagnetic energy. This radio compiles with IEEE and ICNIRP exposure limits for occupational/controlled RF exposure environment at operating duty factors of up to 50 % transmitting and is authorized by the FCC for occupational use only. In terms of measuring RF energy for compliance with the FCC exposure guidelines, your radio radiates measurable RF energy only while it is transmitting (during talking), not when it is receiving (listening) or in standby mode. The approved batteries supplied with this radio are rated at 5-5-90 duty factor (5% talk- 5% Listen 90% standby), even though this radio complies with the FCC occupational RF exposure limits and may operate at duty factors of up to 50 % talk.
Your Datron 2-way radio complies with the following RF energy exposure standards and guidelines:
United States Federal Communications Commission, Code of Federal
Regulations;47 CFR §§1.1307, 1.1310, 2.1091 and 2.1093
American National Standards Institute (ANSI)/Institute of Electrical and
Electronic Engineers (IEEE) C95. 1-1992
Institute of Electrical and Electronic Engineers (IEEE) C95. 1-1999 Edition
RF EXPOSURE COMPLIANCE AND CONTROL GUIDELINES AND
OPERATING INSTRUCTIONS
To control your exposure and ensure compliance with 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 should accompany device when transferred to other
users.
Do not use this device if the operational requirements described herein are not
met.
Operating Instructions:
Transmit no more than the rated duty factor of 50 % of the time. To transmit
(talk), push the Push-To-Talk (PTT) button. To receive calls, release the PTT button. Transmitting 50 % of the time, or less, is important because this radio generates measureable RF energy exposure only when transmitting (in terms of measuring for standards compliance).
Hold the radio in a vertical position in front of face with the microphone (and the
other parts of the radio, including the antenna) at least one inch (2.5 cm) away from the nose. Keeping the radio at the proper distance is important because RF exposure decreases with distance from the antenna. Antenna should be kept away from the eyes.
When worn on the body, always place the radio in a Datron approved clip, holder,
holster, or body harness for this product. Using approved body-worn accessories is important because the use of Datron or other manufacturer’s non-approved accessories may result in exposure levels, which exceed the FCC’s occupational/controlled environmental RF exposure limits.
If you are not using a body-worn accessory and are not using the radio in the
intended use position in front of the face, then ensure the antenna and the radio are kept at least 1 inch (2.5 cm) from the body when transmitting. Keeping the radio at the proper distance is important because RF exposure decreases with increasing distance from the antenna.
Use only Datron approved supplied or replacement antennas, batteries and
accessories. Use of non Datron approved antennas, batteries and accessories may exceed the FCC exposure guidelines.
For a list of Datron approved accessories refer to the accessory section in this
manual or visit
www.dtwc.com.

1: INTRODUCTION
Guardian II Portable Radio
The Guardian II series portable radios are crafted with advanced electronics, software and materials incorporated into a rugged, professional design offering years of reliable service. The radios provide operation in analog or digital, wideband or narrowband modes, and are APCO Project-25 compatible. The Guardian II is available in three separate models (pictured below) allowing the radio to be customized to end user requirements. Numerous combinations of options, features and channel settings are possible using the Guardian PC Programmer.
Standard features include:
1024-channels/ Talkgroups (64 zones of 16 channels/zone)
AES, DES OFB Encryption
P-25 Trunking
P-25 OTAR (Over the Air Rekey)
Backlit LCD
Tri-color LED status indicator
16-position rotary volume and channel knobs
Two programmable collar switches
Emergency and function buttons
Channels can be individually programmed for 25 kHz wideband or 12.5 kHz narrowband operation, analog or digital, clear or encrypted, with transmitter power settable from .2W to 5W. Up to eight shadow channels can be programmed for any channel providing all-mode radio performance. Thirty two encryption keys can be stored in the radio.
Radio Configuration
A radio configuration includes channels, zones and banks.
Channels
Channels contain all the information required to transmit and receive. A channel is referred to as primary when it is differentiated from a shadow channel. The standard radio has a total of 1024 programmable channels. Each channel can be set for: Receive and transmit frequencies
Wideband or narrowband
Analog or digital
Various squelch types
Encryption key
Power output level
12-character alphanumeric channel tag (name)
Zones
Zones provide a way of rapidly switching groups of channels. Each zone can contain up to 16 channels. If the 3 position collar switch set for Zone Select, the radio provides easy access to 48 channels by using the collar switch and the channel select knob. Up to 64 zones can be accessed from the radio keypad or programmable soft keys and displayed in the standard radio. Channels can be mapped to the channel select knob within each zone using the PC Programmer. A zone must be assigned to a bank.
Banks
Banks provide a way of switching a set of zones (containing channels) with a few key presses. For example, the Banks can be programmed with different geographic frequency plans. Up to 8 banks (with a maximum of 16 zones each) can be programmed into the radio. Each bank contains a collection of zones, as well as defined priority channels, a home channel, and an emergency channel.
Shadow Channels
Shadow channels are created and edited using the PC Programmer. Up to 8 shadow channels are available for each primary channel. Shadow channels enable you to monitor and reply (if all settings match) to all transmissions on a given channel. Shadow channels can have different modulation modes (analog or digital), bandwidths, squelch modes, digital network access codes (NAC), or encryption keys than their associated primary channel. Each shadow channel must have the same transmit and receive frequencies, scan list, talk-around, locked options, and transmit power level as its associated primary channel. Shadow
channels count toward the 1024-
channel total radio capacity.
