Attachment Points
The RIA-1 is equipped with two attachment points both on the
bottom side.
3/8" UNC Mounting Point
Use a hexagon socket head key with a wrench size of
3/4/5mm to attach the 3/8" UNC screws. Tighten screws
crosswise.
M4 Mounting Point
Use a hexagon socket head key with a wrench size of
3mm to attach the M4 screws. Tighten screws crosswise.
Attaching a Radio Module
1. Push back and hold the radio module RELEASE LATCH.
2. Remove the RF cover or an attached radio module by sliding it upwards.

ADVICE
Improper Handling of Cables
Risk of damage to the RIA-1.
Operate the system using only the type of power source indicated in this
document. Do not supply power outside the specified voltage range.
Always unplug the power cable by gripping the power plug, not the cable.
Always keep the connectors accessible so that the cable can be unplugged
quickly in case of emergency.
Always properly secure cables connected to the camera to avoid pinching or
tripping.
Do not use any accessories, cables or attachments that are not recommended
by ARRI, as they may damage any connected products and invalidate the
warranty.
ATTENTION
The RIA-1 accepts an input voltage range from DC 10.5 to 34 V DC and can be
powered through the CAM or LBUS connector.
To properly support cforce motors however the RIA-1 requires a voltage of at
least 12V.
In client mode, the RIA-1 will continue running on a voltage of down to 6.5 V, but
connected accessories may no longer run reliably.
Any connected electronic accessories will increase the total power draw.
It is recommended to add an additional power supply connection if three or more
electronic accessories are connected to the RIA-1.
