Key Concepts

In operation, it’s essential to distinguish three different actions:
  • Enable/disable Bluetooth on mobile
    Turn Bluetooth on or off on the phone. Does not involve pairing or connecting to a device.
  • Pair/Link the mobile with a device
    Also called pairing. The mobile registers an external device (headphones, car hands-free, or MX2200’s Bluetooth channel). This is done only once per device.
    A device can be unpaired, meaning deleted from the list of Bluetooth devices linked to the mobile. To use it again, you’ll need to pair it again.
  • Connect/Disconnect a previously paired device
    The mobile connects to one of the previously paired devices. This is different from pairing. With Bluetooth enabled on the mobile, connection/disconnection is done from the list of paired devices.

BLT LED States

The BLT button illuminates in amber with different flashing patterns according to the Bluetooth status:

​
Operation Notes

  • Mode A confirms the mobile is properly linked, ready to use as audio source or backup link.
  • Mode B can indicate two situations: no mobile connected yet, or an active call.
  • Mode C should only be used when pairing a new phone.
  • Mode D acts as clear notification of incoming call, with steady illumination.
Never confuse pairing (mode C) with connecting/disconnecting (mode A/B). Pairing is done only once per phone, while connection/disconnection happens each time of use.
The image shows an example of an Android mobile with a call. Switching between Bluetooth and Speaker allows transferring the call to MX2200 (Bluetooth) or speaking from the phone (Speaker). Android Bluetooth Jp
Interface may vary by system/version: some Android show a Headset/Speaker button, others a menu with options. Check your phone’s manual.

Pairing mobile with MX2200

1

Prepare the console

Ensure Bluetooth is off on the MX2200.
If the BLT button flashes amber with slow intermittence (≈1 flash every 2 s), Bluetooth is on. Press and hold BLT until the LED turns completely off.
2

Enter pairing mode

With Bluetooth off, press and hold BLT ~8 s.
You’ll first see slow flashes (mode B) then fast flashing (mode C). Release the button when it changes to fast flashing: console enters pairing mode and is ready to be discovered.
3

Search from mobile

On the phone, enable Bluetooth and search for new devices (procedure varies by make/model).
4

Select the device

The device will appear as Solidyne BTM641. Select it to pair and then to connect if the system asks twice.
5

Confirmation and name

After pairing, BLT remains with slow flash (Bluetooth active).
On mobile you can rename “Solidyne BTM641” from device settings if desired.
6

Multiple mobiles and distance

You can pair multiple phones with MX2200, but only one can be connected at a time.
Typical range: up to 3 m. Keep mobile nearby, but never placed directly on the MX2200.

​
Re-connecting a previously paired mobile

The mobile can disconnect from MX2200 in various situations. The following table shows what happens and how to reconnect:
Reconnection won’t be possible if the same Bluetooth channel on MX2200 was paired with another phone and that second phone is currently connected.

​
Volume Adjustment

On the mobile, set Bluetooth volume to maximum to ensure good reception and best signal-to-noise ratio.
Make the adjustment during a Bluetooth call. If you change volume without an active call, it modifies the phone’s internal speaker volume and not Bluetooth volume.
  • Bluetooth level remains stored in the mobile.
  • If changing phones, repeat adjustment to set Bluetooth volume to maximum.

​
Turning off Bluetooth on console

To turn off Bluetooth on MX2200, press and hold BLT until LED turns off.
If operating on battery and not using Bluetooth, keep it off to save power.

​
Broadcasting via Bluetooth

1

Console preparation

On CELL PHONE, keep LEVEL control closed and CUE/PGM in CUE (released).
2

Turn on Bluetooth on console

Press and hold BLT ~5 s until it remains lit with slow flash (Bluetooth active).
3

Connect mobile

Before transferring the call to console, verify CUE/PGM is in CUE to prevent call from going on air at transfer moment.
1

Answer if Bluetooth is off

If Bluetooth is off on mobile, answer call from phone then enable Bluetooth to transfer to console.
2

Answer if Bluetooth is active

If Bluetooth is active, you can answer directly from console with a short press on BLT.
In this condition conversation happens only through console.
3

Call transfer

Once transferred to console, mobile receives PGM signal.
4

Private talk

Press TALK in CELL Phone zone and listen on CUE through headphones.
5

Put on PGM

Switch CUE/PGM to PGM and adjust level to send call to program.
6

End call
