3.7.4 Music System Check
1. Set GMA 342/345 to ALL mode with Pilot and Crew button off.
2. Connect a stereo audio source to MUSIC 1. Verify that stereo audio is heard over all headset
positions when MUSIC 1 is selected as the music source and the MUSIC LED is on. Verify that
music volume adjustment is working properly for Pilot, Copilot, and Passengers (if passenger
headsets are wired).
3. Connect a stereo music source to MUSIC 2. Verify that stereo audio is heard when MUSIC 2 is
selected as the music source and MUSIC LED is on.
3.7.5 Bluetooth Music System Check (GMA 345 only)
Use the following steps to Pair and wirelessly connect a Bluetooth equipped phone or tablet to the
GMA 345. Pairing mode allows a new device to discover and create a connection to the GMA 345.
Additionally, pairing mode is used to forcefully disconnect a device currently connected to the GMA 345.
NOTE
The Bluetooth annunciation is illuminated only when a Bluetooth device is connected.
1. Press and hold the TEL (PAIR) Key for one second to enter pairing mode. The Bluetooth
annunciator flashes to indicate the GMA 345 is in pairing mode and “Pairing Enabled” audio is
played. Once the Bluetooth annunciator flashes, the GMA is discoverable for two minutes, or until
a device is paired or connected. While discoverable, a Bluetooth enabled device (e.g., cellphone or
tablet) can find and pair with the GMA. Refer to the device’s instruction manual for information
on how to pair and connect to a new Bluetooth device. Once paired and connected, the Bluetooth
annunciator on the GMA stops flashing and remains lit as long as the Bluetooth connection is
active. The GMA remembers the last 10 paired devices. When the paired devices list is full and a
new device is paired, the least recently connected device is removed from the paired device list.
2. Play music on a device using the Bluetooth connection and adjust the device volume near
maximum.
3. With the MUSIC button on and the Bluetooth music system selected, verify music is heard in the
connected headsets and that the music volume on the GMA 345 adjusts the volume in the headset.
4. Disable radio and ICS muting by pressing and holding the AUX2 key.
NOTE
To ensure the music audio is not being muted by ICS or by COM audio, disable radio and
ICS muting. Also, deselect the PILOT or CREW buttons so that there is no ICS Isolation.
