TELEPHONE HYBRIDS
HL202 & 203VQ
2.3
USING WITH CELL PHONES
2.3.1 Wired cell phones in HL202 & HL203-VQ
Both RJ-11 inputs supports cell phones. The cellular connects to the hybrid using the "free hands"
connection that the cell phones have. For make this you need a special RJ-11 cable-adapter whose
connection will depend on the brand and model of your cell phone. You will need to purchase the
"free hands" accessory correspondent to your cell phone and to check the user manual of the unit to
make the connection according to the diagram showed above.
Cell phone connects directly to "LINE/CELLULAR" RJ11. The hybrid automatically detects the cell
phone and changes the input mode from 2-paths to 4-paths.
The cell phone transmits through the "free hands" connector the audio signals: microphone and
loudspeaker. The HL202/203 receives, via cell phone, the remote audio (that is to say, the audio of
who is at the other end of the line). On the other hand, the hybrid sends to the cell phone the audio
from the Studios (return signal). Usually the microphone and the loudspeaker at the cell phone are
disconnected when the phone operates in "free hands" mode.
Wiring used with
Samsung and others
brands that supports the
standard CTIA.
For OMTP standard
swap MIC with GND.
2.3.2 Bluetooth wireless link (only models HL203-VQ)
HL203-VQ supports connection of a mobile phone via Bluetooth link. Any phone with Bluetooth can
be linked to the HL203-VQ, eliminating dependence on the headset cable, which differs in each cell.
Also allows the cell to be located up to 10 meters away from the hybrid. The Bluetooth wireless link
provides better audio quality since the signal remains digital from the cell phone to the HL203-VQ.
2.3.2.1
Linking the cell phone with the hybrid
By linking cell phones to the hybrid creates a link between two devices, and allows the phone to
remember the unique ID of the HL203-VQ. Do you need to make this only the first time that use the
phone. Once the hybrid and the phone are linked, the hybrid automatically connects to these phone
when you enables Bluetooth on both devices.
Procedure
1. HL203-VQ: Enables discovery mode. With Bluetooth switched off (LED off) press and hold
the button BLUET (5 seconds) until the LED flashes alternating between green and red,
indicating discovery mode. Being in this mode HL203-VQ can be found by the cell phone.
