Today is Sunday and on Saturday I purchased a used HEQ5 Pro. I powered it up and the GPS set date, time and position but the motors won't move. I used my cars 12v to power it up, I have tried replugging everything, unplugged the GPS in case it was interferring and loosened the black knobs on either side of the North leg of the tripod. I don't know if there is something in the handset (Ver 3.12) I need to set. I have read the manual backwards and forwards. Help
