Adjusting The Microphone Sensitivity; Possible Malfunctions - AKE PB-HC2 Bedienungsanleitung

signal can be loud or low. For an optimum operation with a PowerCom
system, the microphone sensitivity of the helmets should be conform.
Test while driving and adjust the microphone sensitivity of the AKE
Bluetooth helmet connector PB-HC2 so that the PowerCom system will
interconnect the microphone at the desired speed when talking (for
maximum sensitivity turn all the way to the right, for minimum of disturbing
noises turn all the way to the left). With integrated Bluetooth gateway the
sensitivity can be adjusted with optional available connector if necessary.

Possible malfunctions

Voice connection only in one direction:
The Stereo mode is activated, push shortly the Bluetooth-operating-
button for switching to Duplex mode.
The connection to the helmet gets lost when starting the engine:
If starting the engine with a low battery and therefore the on-board power
breaks down impulsed below 9V, the electronic might turn off and on
several times, or e.g. switch between duplex and stereo mode! In this case
please start the helmet-intercom-system, eg. with an additional switch,
after starting the engine. Tip: Some modern motorbikes, the light is
switched on only after the engine is started. Then supply the electronics
power with font light.
Before reconnecting the power always wait about 4 seconds until the log
out of the Bluetooth gateway is completed. Otherwise it is possible that it
takes up to two minutes to reconnect or that the reconnection fails.
Audio signal from the radio, etc. overdriven at higher speeds:
Adjust Bluetooth helmet set to high volume and reduce the volume of
accessories and intercom accordingly.
Some Bluetooth noise :
The Bluetooth-to-helmet connections are optimized for distortion-free
operation at high speed. Therefore, it's possible to hear something
ground noise with engine off (dynamic range).
No Duplex / Stereo switching or unexplained malfunctions:
If the Bluetooth devices get mixed up, please turn them off and on again.
Vehicle disturbance when use Bluetooth helmet connector with own power line:
Disconnect Bat.neg.pole or use disturbance free power with AKE Power Stabilizer.
