These keys can be set up to act in two different ways:

Repeating 

(also called typematic) so that if you hold a key down it will

continue to increase or decrease step by step until you release the
key.  This option is active when your throttle is set up for ballistic
tracking. Your DT400 was shipped from the factory with this fea-
ture enabled.

Single Press

so that you will must press the key each time you want to

increase or decrease. This option is active when your throttle is set
up for straight line tracking.

See Section 23.1.1 for  information on changing this setting on your

DT400.
