For all that have an EDS O2-D1 or O2-D2 regulator, there is a Tech
Service Notice out for those regulators. I spoke with Brad
Stankey from Mountain High who informed me of this. I said I'd post
this for him. I'm just the messenger. Below is his contact info, the
Tech Svc notice, and a Q and A form. Good luck.

Mountain High Service Letter Information concerning MHB-060210
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 FREE upgrades.
If you have one of our portable systems and would like the upgrade, we
would also like to examine your regulator to determine if any upgrades
are necessary and to check out its operational parameters.
For your convenience, below are the serial numbers of the units
manufactured before October 2009, that we suggest be up graded to the
latest revisions.
EDS-O2D1 all serial numbers below 01555 EDS-O2D2 all serial numbers
below 02241
Many of you may have had your EDS unit in for service since that date.
You may have already received these technical upgrades. Please e-mail
if you question the need to send in your unit.
Please include your name, the model, serial number, service date and
repair order number if available.
With this information we should be able to determine the status of
your unit.
Before returning your EDS unit contact us at to
obtain a return authorization number (RMA). Please reference this
bulletin (MHB-060210) when making your request. We are expecting the
turn around time to be between 7 to 10 working days after receipt of
your unit.
MH will pay for return ground shipping within the continental United
States. MHO
Q and A
Q. I have one of your portable MH-EDS PULSE-DEMANDTM units. They seem
to be operating just fine, should I send it in for any type of routine
service or testing?
A. Yes. Even though your pulse demand unit will generally let you know
if there is a problem and has been designed to be relatively
maintenance free, except for batteries, it should be sent in on a
regular basis for performance inspection and service. This includes
the in-line or screw-on pressure regulator you use with the EDS. Think
of it
like performing an annual inspection on your aircraft.
Q. Why has this not been mentioned before and how often does MH
recommend this be done?
A. This service program has been derived from usage and servicing data
acquired during the last 10 years the tech- nology has been in
production and fielded. From this, Mountain High has recently decided
on a routine service program that should be accomplished once every
two years, (bi-annually). This must include the pressure regulator you
are currently using with the EDS unit(s).
Q. What is done to my EDS unit and regulator when I send them in for
service?
A. From time to time we make engineering improvements during our
production. These improvements may include changes to hardware or
firmware or both. This is our way of passing on our latest
improvements to you. Also routine service parts such as seals, seats,
O-rings and filters are inspected and replaced. Your EDS unit(s) and
regulator(s) are then thoroughly inspected and tested on our ATP test
set to ensure they are operating to specified standards. This will
help to ensure your system is operating properly and upgraded to the
latest specifications.
Q. How much does it cost me? A. The cost for this service is US $75.00
and includes all firmware and hardware upgrades as well as routine
service
parts. Any other parts replaced due to damage or field use would be
subject to an additional charge.
Q. What about shipping costs and how long should I expect this service
to take?
A. You pay only the shipping to us, and in the continental US we pay
UPS ground shipping back to you. International shipping is to be paid
by customer. Once we receive your unit, in-house turn around time is
generally five to ten working days.
Q. I have sent my EDS unit(s) back once before for a problem of
leaking or not responding at certain altitudes, but it came back with
the same problem. Why?
A. Many problems perceived to be with the EDS unit(s) have in fact
turned out to be with the pressure regulator. This has mostly been the
case if you are not using the MH Regulator designed for the EDS or are
connecting directly to a built-in system installed in your aircraft.
This is why you must include the primary pressure reducing regulator
you are using (ours or not) or tell us that you are connecting the EDS
unit(s) directly to your aircraft’s built-in system without our MH In-
Line Regulator.

the proper amount of oxygen. Damage can be done to the breathing
sensor in the EDS unit(s) if the operating pressure is too high.
Additionally, we have seen many situations where customers connect the
EDS unit(s) to the connectors and tubing that came with their
aircraft, then plug them into the high pressure outlets in the
aircraft. This has caused a lot of confusing problems because these
connectors generally have flow restriction orifices. In many cases
this has allowed the EDS unit(s) to check out okay at ground level
when the pulse response is low, but then activate with flow fault
alarms
at higher cruising altitudes. Additionally, this problem can be
difficult to reproduce because the EDS unit(s) operate with pressure
altitude and not barometrical corrected altitude.
