Technical Service Notice



Technical Service Notice



In October of 2009, Mountain High Oxygen engineered technical improvements to our EDS-O2D1 and O2D2 legacy products.  These improvements include technical advancements involving both the hardware and firmware.

To provide our customers with the finest product, we are suggesting to our customers that they send in their units for these improvements.
This recommended routine service program should be accomplished once every two years  (biennially).  
If you have one of our portable systems and would like the upgrade, we would also like to examine your pressure regulator to determine if any upgrades are necessary and to check out its operational parameters.

The cost for this service is US $95.00 plus shipping.
Pressure regulator service is additional $56.25.
This includes all firmware and hardware upgrades as well as routine service parts. Any other parts replaced due to damage of field use would be subject to an additional charge.

Many of you may have had your EDS unit in for service since that date. You may have already received these technical upgrades. The latest Firmware upgrade is Rev. 2K
