• Increased time taken to establish connections with other devices, emergency
broadcast, and Find Me broadcast.
• Device LEDs will light up less often.
• Number of allowed connections will be limited to 1. If the Power Saving Mode is
enabled on the phone, the device will remain connected only to the phone.

enabled, the device will disconnect from all existing connections except the device
closest within range using Bluetooth signals.
Noise Reduction
Three different enable/disable settings can be specified from within the smart phone
companion app to reduce unwanted background noise interfering with short range
streamed and push-to-talk communication:
• Directional selection preferentially amplifies short range communication from the
direction inline with the two Metis microphones. Applies to short range streamed
communication.
• Dynamic filtering removes persistent background noises occurring at fixed
frequencies. Applies to short range streamed communication
• Quality improvement removes irritating background noise from otherwise intelligible
speech. Applies to short range streamed and push-to-talk communication.
Impulse Noise Cancellation
If you are working in an environment that is quiet for most of the time, but have some
impulse loud noise (e.g., operating jackhammer or nail-gun) it is recommended to use
the Compression feature. With the Compression feature enabled, the device will detect
any sudden loud sound and block it in 1/1000 of a second. To experience this feature,
you need to bring the volume slider up to have some hearing from your surrounding
sounds.
Enable Warning Detections
Enable/Disable the warning detection/digital ear feature. Disabling/Enabling the ‘Enable
Warning Detections’ will disable/enable all types of warning detection. You can also
disable/enable detection for individual warnings. When disabled, the user will NOT be notified
if a loud sound or warning sound is detected.
Sensitivity Level
Setting the sensitivity for detecting truck backup alerts. When the sensitivity is at low, the user
may NOT be notified of some detections.
Call Notifications
Enable/Disable notifications to your device whenever you are receiving a call.
