+ Dual Deploy. This is the usual mode of operation; the

+ channel at the height above ground specified by the
+ 'Main Deploy Altitude' during descent.

+ <title>Pad Orientation</title>
+ <para>
+ Because it includes an accelerometer, TeleMetrum is
+ sensitive to the orientation of the board. By default, it
+ expects the antenna end to point forward. This parameter
+ allows that default to be changed, permitting the board to
+ be mounted with the antenna pointing aft instead.
