ENGLISH
To enable the Bluetooth, press and hold the button BLUET by 2 seconds. Release the
button just when LED lights. Led will flash in green slowly, indicating Bluetooth enabled. If
you hold BLUET button more that 2 seconds (5 sec approx) Bluetooth switch to
"discovery" mode (LED will flash alternating green and red).
2. At the cell phone, search for Bluetooth devices. This procedure varies by brand and model
cell, see the user's manual of the phone.
3. When the phone finds the HL203's device, shows the code "BTH008" or "BTM751" on
screen. When the phone asks for the password, enter 0000 (default). See your phone's
manual for details.
4. HL203's ID is now stored at the cell phone's memory. You don't need to repeat this
procedure for this phone. In the front panel of the hybrid, the light will change to green
flashing slow, indicating that Bluetooth is active.
In some cell phones, it is necessary to "connect" the new device found to active it. In
others, the new device is activated after being detected.
If there were other systems operating in the Bluetooth studios, we commend turning off
Bluetooth on the MB-2400, to repeat the search with the cell and write-down the existing
devices. Then turn on Bluetooth in the HL203 and repeat the search. The displayed (BTH-
008) will HL203.
2.3.2.2 Re-connections
To reconnect the cell phone before linked, activate the HL203's Bluetooth pressing by 2 seconds the
button, and enables Bluetooth at the cell phone (if necessary, some cell phones disables Bluetooth
device when turn it off). To make or receive a call, the audio is sent to the hybrid.
2.3.2.3 Adjusting the volume
At the cell phone, Bluetooth volume must be adjusted at maximum level in order to obtain a good
reception and to sure the best signal to noise ratio.
This adjusting must be done with a real calling using Bluetooth. Usually, the volume of the phone's
speaker is independent of the volume of Bluetooth device. If you change the phone's level without
make a Bluetooth calling, you will only be changing the volume for the phone's speaker, not the
Bluetooth level. To change the Bluetooth
level, make a call using the hybrid (or a hands free headset) and set the Bluetooth level to the
maximum. This setting is stored at the cell phone's memory. If you use another cell phone with the
hybrid, you needs to set the Bluetooth level again.
To turn off HL203's Bluetooth, press and hold the Bluetooth button until LED turn off.

AUDIO CONNECTIONS
2.4.1 Connecting to a console using send/return for external Hybrid
If the on-air console have send and return to connect an external hybrid, the connection is simple.
The output connects to HL-202/203 "Return from external hybrid" console (which is an input).
Note that the output of the hybrid is balanced.
HL202/203 input connects to "Send to external hybrid".
This outpus is mix-minus , that is to say, is the PGM mix but without the hybrid signal (the
input "Return from hybrid").
consoles usually don't have mix-minus outputs. For this cases, see connections in "2.2.4 –
To connect this output to an unbalanced input, leave unconnected pin 3 (connect only: 1=gnd;
2=signal).
This avoids feedbacks loops.
