If there is “tick tuck” sound can hear from Display when press “next” on Display . This mean the Relay is okay and the problem might be the either internal wiring within Display or “bell” has out of order. Either the Wire connect to the “bell” has drop or the “bell” itself has out of order.

A technician has to take down the Display and open the board at the back of Display to check whether any wire connected has drop.

Connect back the wire if any wire has drop and see the bell will ring again or not.

If all wire inside Display are connected properly after open the board at the back of Display. This mean the bell is out of order. Usually, a small blue light on the bell will not on. This mean the bell is out of order. You can return the Display to us to change a new bell if it is still under warranty period.

 

5. What to do if the printer number never never change after reset in the morning. Printer keep on print out ticket number 1000 and 2000 no matter how many person queue up, or printer continue with yesterday queue like 1145 and 2146 etc even Display number has reset and start with 1000 and 2000?

Check all the wiring to printer by unplug all the connection and re-plug in again all the wiring. Usually, it will function properly after unplug and re-plug. There is a small blue light on the printer and the light will on if wiring connection is okay and printer is on.

There is also a small switch beside the printer. Check to see anybody/customer accidentally switch of the printer and on it again.

Again, there is a small blue light in front of printer and the light suppose to on if the switch is on.
