• TDMA technology strengthen the capacity of the channel
• Voice encryption: If the radio has set the voice encryption by some system, which can help to protect the voice call of the encrypted channel from the disturbing
• General call, group call, indibidual call, emergency call
• Kill radio, relive radio, remote wake-up under loss, stolen or special dispatching events
• Monitor function: it can use to check the operating channel working or not
• Distance monitoring: Customer can get the environment voice according to monitor some radio in long-distance without informing or giving any hints to the monitored one
• Channel Scanning: Customer can set the scanning on or off by system, so it can receive or send information by finding the operating channel according to scan the special channel in the list
• Battery indicator
• Auto-power-off: if the radio is not in working situation, it can turn into the energy save mode, which can help to add the working time
• Noise eliminating: Eliminate the noise which can help to keep the phone quality
• USB: help to transfer information between the radio and the computer
• Radio Test: checking the equipment in distance to make sure of it work or not
• Voice Reminder: reminding of the working conditions
• High/low power choices
• GPS positioning: set a region on the map, we will be able to check the position of vehicle through entering the number of onboard device
