RF Energy Exposure Compliance
Your radio is designed and tested to comply with a number of national and international standards and
guidelines (listed below) regarding human exposure to radio frequency electromagnetic energy. This
radio complies with the 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 in PTT
mode), not when it is receiving (listening) or in standby mode.
The device complies with SAR and/or RF field strength limits of RSS-102 requirement and contact
information where the user can obtain Canadian information on RF exposure and compliance.
Your radio complies with the following of RF energy exposure standards and
guidelines
● United States Federal Communications Commission, Code of Federal Regulations; 47CFR part 2
sub-part J
● 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
● International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998
Operational Instructions and Training Guidelines
To ensure optimal performance and compliance with the occupational/controlled environment RF energy
exposure limits in the above standards and guidelines, users should transmit no more than
50% of the time and always adhere to the following procedures; and should transmit no more than 50% of
the time, although the hardware support transmission up to 100% of the time in analog mode and up to
50% in digital mode.
Transmit and Receive
To transmit (talk), push the Push-To-Talk (PTT) key; to receive, release the PTT key.
EU Regulatory Conformance
The equipment is in compliance with the essential requirements and other relevant provisions of the
Directive 1999/5/EC.
Note: The above information is applicable to EU countries only.
FCC Licensing Information
Part 15 Compliance
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant
to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, which can
be determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
● Reorient or relocate the receiving antenna.
● Increase the separation between the equipment and receiver.
● Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
● Consult the dealer or an experienced radio/TV technician for help.
FCC Licensing Requirements
A license from Federal Communications Commission is required prior to use. Your dealer will program
each radio with your authorized frequencies, signaling codes, etc., and will be there to meet your
communications needs as your system expands. Contact your dealer for more information.

Signaling Introduction
The radio supports the following signaling. You can ask your dealer to make appropriate settings on your
radio. For detailed information, please contact your dealer.
HDC1200
The HDC1200 signaling is compatible with the MDC1200 signaling, and realizes functions such as PTT
ID (Encoding & Decoding), Emergency (Encoding & Decoding) and Selective Call (Encoding &
Decoding).
Encoding:
1. Hold down the PTT key during normal voice communication to send PTT ID.
2. Go to the menu “Contact List” and select a required contact. Then hold down the PTT key to send a
selective call (Private Call/Group Call/All Call).
For encoding, the radio will provide the following indications:
PTT ID/Selective Call: Your dealer can program whether the radio sounds side tone during encoding
or sounds beeps after encoding.
Selective Call: During encoding, the LED glows red, and the LCD displays the appropriate call icon
(Private Call: ; Group Call: ; All Call: ).After encoding, the LED glows
orange.
Decoding:
For decoding, the radio provides the following indications:
PTT ID: After decoding, the LCD displays the icon and ID or alias of the transmitting party.
Selective Call: After decoding, the radio provides the following indications:
Alert: The radio will sound default alert.
LED: The LED glows green.
LCD: If your dealer enables the feature “Display Decode ID”, the radio will display the
appropriate call icon (Private Call: ; Group Call: ; All Call: ) and
