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.
To connect this output to an unbalanced input, leave unconnected
pin 3 (connect only: 1=gnd; 2=signal).
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”).
This avoids
feedbacks loops.
Note that the live show or studio consoles usually
don't have mix-minus outputs. For this cases, see connections in
“2.2.4 – Connection to studio consoles...”
