Paul,

Not the whole story on the EW MicroRecorder.

"Turning OFF – Disconnect the external power and press switch twice, or
disconnect power and wait for
the Auto off criteria to be met."

"Auto Off Criteria – If during the Auto-Off Time period neither the speed
nor height change
exceeds the Auto-Off Velocity or Auto-Off Altitude values then the
microRecorder will switch off
automatically, (providing it is not connected to external power)."

So the EW has the advantage that if the external power dies while it is in
the air, it continues to run on the battery while it is in the air. And if
it is running normally on external power in flight and you switch off the
power after landing, the unit will switch off the battery power after a
pre-set time.

This is why I have got an EW as my standby recorder mounted behind my
instrument panel. Like Greg, neat though it appears to be I could not see
that the Nano would work as a standby unless you had access to manually
switch it off.

Hi Greg,

Since it has a built-in battery, it is true that you can't power it
down
by
removing 12V power input. But the same is true for the EW microRecorder
and
other similar devices that have internal batteries. The advantage is
that

if you power it with 12V power from your glider battery, and the glider
battery dies, the Nano (or EW) will continue to log your flight using its

internal battery. That would not be the case for any logger that does
not

have an internal battery - such as the LX Colibri or Volkslogger.

The Nano is a fine product, my only complaint..... If you locate the
Nano
in
an isolated area, there is no way to power it off without using the on
off

switch. (unless i have not figured it out).
