About this item：

Power-off Memory is the highlight of this queue calling system. When you switch on this function，the last number called is automatically stored. The call will start with "last number +1" when the power is reconnected.
The number starts at 00 and ends at 99 by default. You can set the "Start" and "End" numbers as needed，for example，you only need to call numbers from 10 to 50. After the call reaches the "End" number，the system will automatically restart from the "Start" number.
The number display can be mounted on a wall or desktop. Easily adjust volume，voice mode，number of broadcasts，cycle time，etc. The default voice mode is "DINGDONG + Number XX".
Quick Zero：Suppose you set the "Start" number to 10 and the current call goes to number 35. Press the UP and DOWN keys at the same time to quick zero. When you press the NEXT button，the number starts calling from 10 again. Note that ZERO here is not necessarily the number 00，but the "Start" number you set.
Convenient Remote Control：You can press the number you want to call temporarily and then press the NEXT button for a quick call. As long as the number you select is within the range of the start and end numbers，this queue number system will do so easily.
