Please Touch/Hold both the UP and DOWN buttons together until the LED display blinks. The desk will lower itself to the lowest desk height. The reset is complete once the desk hits the very bottom and bounces back slightly.
If for some reason the issue persists, please email us at support@apexdesk.com, along with a copy of your original order info. One of our customer service representative will be able to assist you promptly and properly.
Thanks,
ApexDesk Support
