About this item：
- 【Simple Number System】This queue call system is suitable for the scenario where each counter handles the same business. The display can alert customers who are waiting for service that it's their turn and go to any available counter. Improve efficiency and save customers' time.
- 【Clear LED Number Display】The display uses outdoor high-brightness lamp beads to avoid unclear vision when viewed from a distance. The signal range is up to 150m（500ft）in an open area and 30-50m（100-160ft）in obstacle field.
- 【Long Time Display】When you press the CALL key，the display will broadcast "Next customer，please go to counter X". The counter number will remain displayed until the CANCEL key is pressed. So there is no need to worry about the customer missing a call.
- 【Plug and Play】The counter call system does not require a network connection and does not cost anything. We've paired the button transmitter with the display receiver before shipping，it is ready to use when connected to a power source.
- 【Multi-Scenario Application】Clinics，banks，service hall，phlebotomy centers，offices，nail salons，hairdressers or other noise places that require lines.
Attention：It works even better if you prepare your own three sheets of paper with the counter numbers 1，2 and 3 written on them. Simply stick them on the appropriate window，door or table.
Counter pager use process：
1. Customers wait in line.
2. Staff call customers in queue order.
3. Customers go to the idle counter to get service.
4. After the customer is seated，the staff presses the CANCEL key to cancel the call.
Tips：When the display shows the counter number，it means that the counter/room is available；when it show "- - -"，it means that it is in service.
