Adaptive Feedback Canceller Plus
The Adaptive Feedback Canceller Plus in Chronos
automatically calculates the predicted feedback
limits (shown as a dashed purple line). For greater
accuracy, it is beneficial to measure the actual
feedback limits for your client. Click on “Measure”
and follow the prompts. The feedback manager
settings can be adjusted to ensure feedback-free
listening for your client in all programs.

Logging and Learning
Data logging
The data logging in Chronos records operational
statistics including program usage, listening envi-
ronments, user adjustments and feedback moni-
toring. Click on the appropriate button to view the
logged data. Note that the instruments must be
worn a minimum of 8 hours before statistics are
available.
VC learning (CN9 and CN7)
Chronos has a learning feature that works to track
volume control changes and gradually modify the
volume level setting over time to match the level
preferred by the listener. Learning is available for
all microphone programs and can be enabled in
Oasis. Volume level changes are applied after
20 hours of learning in the same program.
