The cash register just shows a series of 000000000 on the screen.
I've tried resetting it by turning it off on register mode and leaving it 30 mins. Nothing has changed. When I turned the till back on it is continuously beeping with nothing on the screen.
If I turn it to off and back to register the beeping stops and the 0000000000 come back up...
1. Remove the register from its packing carton.
2. Insert one of the supplied mode keys into the
mode switch and turn it to the REG position.
3. Insert the plug into the AC outlet.
IMPORTANT: This operation must be performed
without batteries loaded.
4. The buzzer will sound three times. Now your
cash register has been initialized. The display
will show "0.00" with “¬”.
