Embedded information and serial number
Information frequency may be written or recorded maintenance history, convenient maintenance and service; Serial number can be read by writing frequency software, through the serial number on website directly in the center of the state administration of work safety communication information query information such as product authenticity and manufacture date.
Voice channel to broadcast
Boot and adjust the channel automatically broadcast channel, loud noise, and avoid the wrong operation.
Work alone
After enabling this function for walkie talkie set separate work time length, every time reaches a critical time, interphone will alarm prompt, and at the same time, the user must press any key, show that in the safe state; Without operating radio will automatically alarm. This function for users of separate work environment provides a higher security.
Backwards (optional)
After entering run backward mode, if the machine is in flat or the ground state, more than set time, radio will automatically alarm. The interphone to the centralizer, can cancel the alarm.
Emergency alarm
After press the alarm button, walkie-talkie can send out alarm sound at maximum volume, at the same time, their own identity (ENI) or background to peer or system.
Safety inspection
Set this function, the control center or other user signal detection, walkie-talkies receive signal, will prompt the user press any key in a safe state, no reaction is auto alarm.
