No, we do not give out advance replacements. You can put in a new PO for a new unit and return the defective unit. If the unit was purchased within 60 days and is found to have a manufacturers defect, credit can be issued. If the unit was purchased more than 60 days prior, the unit will be repaired and returned under warranty. If the unit is 'No trouble Found' it will be returned to the customer. If the unit has a non warranty defect caused by abuse or neglect, the unit can be repaired for a fee or returned to the customer. If a unit is returned to the customer for any of the above reasons, the customer will still be responsible for the new unit they purchased.
