RF technology is widely used in communication, medicine, food processing and other fields. It may generate radiation during use.   RF Radiation Safety In order to ensure user health, experts from relevant industries including science, engineering, medicine and health work with international organizations to develop standards for safe exposure to RF radiation. These standards consist of:   ¾  United States Federal Communications Commission, Code of Federal Regulations; 47CFR part 2 sub-part J;   ¾  American National Standards Institute (ANSI)/Institute of Electrical and Electronic Engineers (IEEE) C95. 1-1992;   ¾  Institute of Electrical and Electronic Engineers (IEEE) C95. 1 – 1999;   ¾    International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998; FCC Regulations Federal Communication Commission (FCC) requires that all radio communication products should meet the requirements set forth in the above standards before they can be marketed in the U.S, and the manufacturer shall post a RF label on the product to inform users of operational instructions, so as to enhance their occupational health against exposure to RF energy.   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:         (1) Your radio radiates measurable RF energy only while it is transmitting (during talking), not when it is receiving (listening) or in standby mode.          (2) Keep the radio at least 2.5 centimeters away from your body during transmission.
                                                                                                             4EU Regulatory Conformance As certified by the qualified laboratory, the product is in compliance with the essential requirements and other relevant provisions of the Directive 1999/5/EC. Please note that the above information is applicable to EU countries only.     Safety Instructions To protect you against any property loss, bodily injury or even death,   be sure to observe the following safety instructions:   z  Use only the Ex-battery BL1807-Ex specified by the Company. The use of other batteries may result in Ex-protection failure. z  Charge the battery in a non-hazardous area only with the designated charger. z  Use the accessories specified by the Company only.   z  Do not carry any standby battery into a hazardous area. z  Do not use a damaged antenna. If a damaged antenna comes into contact with your skin, a minor burn may result. z  Do not expose the radio to direct sunlight for a long time, nor place it close to a heating source.   z  Hold the radio upright and keep its microphone 2.5 to 5 centimeters away from your mouth during use.  z  If you wear a radio on your body, ensure its antenna is at least 2.5 centimeters away from your body during transmission. z  Do not carry the radio into Division 0. z  Do not disassemble the radio or replace the accessories in a hazardous area. z  Do not modify the intrinsically safe radio in any way . Unauthorized modification of the radio may result in termination of Ex-protection.

You can ask your dealer to make appropriate settings on your radio. For detailed information, please consult 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 Display Decode ID feature, the radio will display the appropriate call icon (Private Call:  ; Group Call:  ; All Call:  ) and alias of the transmitting party (ID of the transmitting party will be displayed if it is not in the contact list). If your dealer does not enable the Display Decode ID feature, the radio will display the appropriate call icon only.
                                                                                                             435-Tone This radio can realize various types of calls through 5-Tone signaling.   Encoding: 1.  Request your dealer to configure the correct format and type for the encoding contents.   2.  When the format consists of fields for variable information, you need to fill in such fields by manual entry or menu operation. When the format consists of fixed codes only, you do not have to edit such fields or save such data.   3. Press PTT key or the programmed One Touch Call 1-One Touch Call 5 keys to send the 5-Tone signaling.  During encoding, the radio sounds a side tone, the LED glows red, and the LCD displays the contact information (or “Five Tone Call”) and an appropriate call icon (Private Call:  ; Group Call: ). If Auto Reset is enabled (by your dealer), your radio will enter the Auto Reset mode after successful encoding, with LED glowing orange, until the Auto Reset Time expires.   Decoding: Your radio can automatically decode the 5-Tone signaling when receiving any matched one.   During decoding, the LED glows green. After successful decoding, the LCD displays the contact information (or “Five Tone Call”), an appropriate call icon (Private Call:  ; Group Call:  ), and the decoded status message. If Auto Reset is enabled (by your dealer), your radio will enter the Auto Reset mode, with LED glowing orange, until the Auto Reset Time expires.    2-Tone With this signaling, the radio can transmit and receive 2-Tone calls. Encoding: 1.  Request your dealer to configure the correct format and type for the encoding contents.   2. Press PTT key or the programmed One Touch Call 1-One Touch Call 5 keys to send the 5-Tone signaling.  During encoding, the radio sounds a side tone, the LED glows red, and the LCD displays the call icon   with contact information above it. If Auto Reset is enabled (by your dealer), your radio will enter the Auto Reset mode after successful encoding, with LED glowing orange, until the Auto Reset Time
                                                                                                             44expires.   Decoding: Your radio can automatically decode the 2-Tone signaling when receiving any matched one.   During decoding, the LED glows green. After successful decoding, the LCD displays the call icon  and the call type (selective call, alert call w/voice, alert call) below the icon according the decoding type.   If Auto Reset is enabled (by your dealer), your radio will enter the Auto Reset mode, with LED glowing orange, until the Auto Reset Time expires. The radio cannot enter the Auto Reset mode if it is an alert call.  Troubleshooting  Phenomena   Analysis   Solution   The battery may be improperly installed.
