Zaon MRX causing radio interference

Do you know if this function is available in older MRX versions? The
manual which came with my unit (bought August 2006) does not mention
such a capability. I see that the latest manual on the Zaon web site
does explain how to access this function, though. I'll see if my unit
allows me to get to the altimeter calibration menu when I'm next at
the airport.

The MRX internal baro altitude is both displayable and adjustable. It
should not require any other equipment, except an accurate altimeter
set to 29.92, to determine if the problem is the MRX baro sensor.

Don't know when this feature was included. I would suspect it has
always been there but maybe not documented in the user manual. I have
a fairly early unit but I had it upgraded to the latest firmware last
year as I needed the new function that distinguishes whether the
internal baro sensor, or the host aircraft transponder, is being used
for reference altitude. I had not attempted the baro calibration
before the firmware update.

If you have no host aircraft transponder, pressing the multifunction
switch left will report the internal pressure alt being used. If you
do this several times and always see the same pressure altitude it
would suggest that the internal baro sensor is not erratic. If you
find it is constant but not correct, then try the calibration
procedure.

I have found Zaon customer service to be excellent so don't hesitate
to contact them if you need to.
