Imaging System. This design is ergonomic and user-friendly for both
right and left hand operators. The HCU is a multifunctional device
employing natural contours and easily reached buttons to activate the
different functions. All controls are located to allow the operator to grasp
the unit and use the fingers to operate the controls. The unit has an
adjustable hand strap to prevent it from slipping out of the operator’s
grasp in confined areas. The HCU is provided with an expanding coiled
cord to protect against “tugging” on the connector. The HCU is
connected directly to the CEU for system operation. HCU characteristics
are listed in Table 1-8.

1.5 System Power Information
The CEU receives a nominal +28VDC from the host and distributes the
voltage to the SGA.
NOTE:
Anti-Ice electrical power is provided directly to the SGA from the
host. The Anti-Ice should only be used when the SGA is
below 32°F.
