Operator Interface
The
Stripe
(see Figure B.2 below) is an ergonomically designed vertical area along the
right-hand side of the display. It comprises a number of visual indicators and mechanical
keys with a proper tactile feedback in order to provide the operator with a quick insight and
immediate access to important controls. The most prominent position is assigned to the
PTT key, which consists of a full-travel mechanical key-switch and a large actuator with
dimmable background illumination. Several additional LED indicators (see Figure B.3) are
located in a Stripe extension on the left-hand side of the display.
