Radio Pack
The CrewCom Radio Pack is available in a 4Vol (CRP-44) and a 2Vol (CRP-22) model and can be used with the
CrewCom system in highly-varying applications and environments. Each of these models are identical, other than the
number of controls and their related profiles.

Volume Knobs/ISO Buttons
The volume controls adjust the listening volume of the connected headset for each of their respective assigned
conferences. Turning the volume control clockwise increases the audio level, while turning the control counter-
clockwise decreases the level.
When pressed, the volume knobs also serve as ISO buttons to allow selective talk around. ISO means that selected
users can have an isolated conversation with other ISO-enabled users. While an ISO conversation occurs, the main
conference audio can still be heard. ISO must be separately enabled on both the Conference and each desired Profile
from CrewWare. (See
"Wireless ISO" on page 47
for more information.)
Four volume knobs are available on the CRP-44 Radio Pack, and in CrewWare, they are named A, B, C, and D from
left to right with the knobs facing away from you.
