What to do
• On the AUX source, turn the volume up.
• Make sure the 3.5 mm AUX audio cable is firmly connected to the
control module and the AUX source.
• On the control module, make sure the Secondary Audio Mode
selector is in the MUTE or MIX position.
• If the Secondary Audio Mode selector is set to MUTE, all
secondary audio sources are temporarily muted when an intercom
signal is detected. Secondary audio will return after intercom audio
ceases.
• If you are on an active Bluetooth phone call, you will not hear audio
from the AUX source. AUX audio will resume after the phone call
ends.
• Try another AUX source.
• Make sure the 3.5 mm AUX audio cable is firmly connected to the
control module and the AUX source.
• On the headset, make sure the terminator cover is in place and
properly connected. Refer to "Attaching the microphone assembly"
on page 10.
• Make sure the headset is firmly connected to the intercom/radio
system.
• Make sure the 3.5 mm AUX audio cable is firmly connected to the
control module and the AUX source.
• Inside battery compartment, check the Priority (BT-AUX) switch.
See "The operation switches" on page 11pages 11-12.
• If the Secondary Audio Mode selector is set to MIX, all secondary
audio sources are heard as mixed with the intercom audio. To mute
the AUX source, set the switch to MUTE or OFF.
• The headset does not support microphone operation when con-
nected to a device via the AUX audio cable. Hold the device closer
to your mouth to use the device's mic. Or, try connecting the
phone via a Bluetooth connection.
