+         TeleMetrum and TeleMini provide two igniter channels as they
+         were originally designed as dual-deploy flight
+         computers. This configuration parameter allows the two
+         channels to be used in different configurations.

+             Dual Deploy. This is the usual mode of operation; the
+             'apogee' channel is fired at apogee and the 'main'
+             channel at the height above ground specified by the
+             'Main Deploy Altitude' during descent.

+             delay by the 'main' channel.

+         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.
