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:| Mode | Status | LED Indication | Meaning |
|---|---|---|---|
| A | Mobile connected | Brief ON (1 s) + long OFF (2 s) | Mobile is connected to MX2200, no active call |
| B | Mobile not connected / Call in progress | Slow ON (2 s) + short OFF (1 s) | - Bluetooth on but no mobile connected - Or mobile has an active call - When a mobile connects, status changes to A |
| C | Search mode (Pairing) | Fast flashing | Allows phone to find and pair with MX2200 |
| D | Incoming call | Steady ON | Indicates an incoming call |
| — | Off | No illumination | Bluetooth off |
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.
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
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.

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.

Search from mobile
On the phone, enable Bluetooth and search for new devices (procedure varies by make/model).
Select the device
The device will appear as Solidyne BTM641. Select it to pair and then to connect if the system asks twice.
Confirmation and name
After pairing, BLT remains with slow flash (Bluetooth active).
On mobile you can rename “Solidyne BTM641” from device settings if desired.

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:| Situation | What happens to the call | How to return to MX2200 |
|---|---|---|
| Bluetooth turned off on mobile | Call usually transfers to phone (behavior may vary by make/model) | Turn Bluetooth back on; reconnection may be automatic or select Solidyne BTM641 from list |
| Mobile disconnected from Bluetooth device | Call exits Bluetooth and goes to phone | On mobile reconnect to Bluetooth Solidyne BTM641 to return it to console |
| ”Speaker” activated on mobile | Call exits “hands-free” mode (Bluetooth) and goes to phone | Switch to “Headset/Bluetooth” on mobile to return to console |
| Bluetooth channel turned off on MX2200 | Bluetooth link cuts off. Call usually transfers to phone. | Turn on BLT and reconnect from mobile |
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
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
Turn on Bluetooth on console
Press and hold BLT ~5 s until it remains lit with slow flash (Bluetooth active).
- Incoming call (Bluetooth)
- Call from mobile
Answer if Bluetooth is off
If Bluetooth is off on mobile, answer call from phone then enable Bluetooth to transfer to console.
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.
