35 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 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 feature “Display Decode ID”, the radio will display the appropriate call icon only.
36 Troubleshooting Phenomena Analysis Solution The radio can not be powered on. The power cord may be unconnected. Connect the power cord correctly. The volume may be set to a low level.

During receiving signals, the voice is weak, discontinuous or totally inactive. The speaker may be blocked or damaged. Clean surface of the speaker. If the problem can not be solved, contact your dealer or our authorized service center for inspection and repair. The frequency or signaling may be inconsistent with that of other members. Set your TX/RX frequency and signaling to the same as that of other members. You can not communicate with other members in Analog mode. You may be too far away from the group members. Move towards other members. And make sure that you are within the communication range. You can not communicate with other members in Digital mode although there is receiving indication. Your ID may be inconsistent with that of other members. Consequently, the digital carrier can be received but can not be demodulated. Set your ID to the same as that of other members. You may be interrupted by radios using the same frequency. Adjust the squelch level. Irrelevant communications or noises are heard on the analog channel. The radio may be set with no signaling. Set your radio with signaling to avoid interference at the same frequency, and make sure that all members share the same signaling. You may be too far away from other members. Move towards other members, and then try again. You may be at an unfavorable position. For example, your communication may be blocked by high buildings or frustrated in the underground areas. Move to an open and flat area, and try again. The noise is too loud. You may suffer from external disturbance (such as electromagnetic interference). Stay away from equipment that may cause interference. You can not use the keys. The keypad may fail to function temporarily. Restart the radio. There is no display. The LCD may fail to function Restart the radio.
