6.5.5 Radio Module Interface
The RIA-1 contains a radio module interface for ARRI's
exchangable radio modules (RF-EMIP Radio Module 2400 MHz
DSSS, RF-2400 Radio Module 2400 MHz FHHS and RF-900
Radio Module 900 MHz FHHSS).
ATTENTION
Always keep the Radio Interface clean and dry!
Do not leave the Radio interface open during transportation
and storage. Attach the RF Cover or a radio module instead

The Hi-5 knob contains two spring-loaded pins as an interface
for ARRI's Smart Focus Rings. They establish an electrical
connection between the chip on a Smart Focus Ring and the Hi-5
hand unit.
6.6 Screen Pages
6.6.1 Lens Data Display (LDD)
The Lens Data Display (LDD) is the default screen. It displays
the most important parameters of the hand unit and the host of
the camera side, and shows the current position of the motors
attached to the focus, iris and zoom lens rings.
The distance readout of compatible measuring devices such as
the Ultrasonic Distance Measure UDM-1, Cine RT, Cine Tape,
Ward Sniper or cfinder III will automatically appear on the LDD
screen if connected to the respective camera host. The distance
readout is displayed as a number above the focus value in the
center of the LDD screen and as an arrow on the LDD focus
scale.
