automatically. After the call has been bung up, the system will
auto return to intercom talking or music playing state.

will launch an intercom talking after hanging up the call, the
system will return to the music automatically.

talking”start after the “cell phone talking” has been hanged up.
Troubleshooting
1) Not Working
Could be a flat battery, charge the BIM 3 hours.
2) Reset
ln some regions of high RF strength ie near high power TV
transmitters, GSM station or airport radars, these can overwhelm
the CPU in the BIM causing it to latch up however, a short press
the reset Reset key (the gray key near the Power/lnterphone key)
and power/lnterphone key simultaneously, or charge the unit,
will normally work again.
3) No sound
Physically checks to see the headset cables are ok swap with the
other functioning BIM to localize the problem. Have you turned to
volume too low?
4) Whistling of the speakers
lf the microphone is too closed a speaker, the speaker will make a
whistling, take the microphone away from the speaker, it will be ok.
