How to Make Wireless Connection with
BLUETOOTH Devices
You can enjoy music and hands-free calling with the system wirelessly by using
your device’s BLUETOOTH function.
Choose one of the following three connection methods, best suited for the
BLUETOOTH device. For details on how to operate your device, refer to the
operating instructions supplied with the device.
Pairing with a BLUETOOTH device: see
Pattern A
BLUETOOTH devices need to be “paired” with each other beforehand.
Connecting with a paired device: see
Pattern B
To listen to music with a BLUETOOTH device that has been paired, see this
pattern.
One-touch connection with a smartphone (NFC):
see
Pattern C
Using an NFC compatible smartphone, you can establish BLUETOOTH connection
by just touching the system with it.
For details about NFC, see “About NFC” in
Pattern C
.
Check the following before operating the system.
Both the system and the device are placed within 1 m (3 ft) of each other.
The system is connected to a power source.
The operating instructions supplied with the device are kept at hand.
Pattern A
Pairing and connecting with a BLUETOOTH device
1 Set the BLUETOOTH function of the BLUETOOTH device to
on.
For details, refer to the operating instructions supplied with the device.
2 Press and hold BLUETOOTH PAIRING on the system
until beeps are heard and “
(BLUETOOTH)” begins to flash
quickly in the display.
Tip
From the factory, pairing information is not stored in the system. In this case, if you only
press
BLUETOOTH PAIRING , “ (BLUETOOTH)” starts flashing quickly in the
display.
(BLUETOOTH)
flashes quickly
3 Perform the pairing procedure on the BLUETOOTH device to
detect the system.
If “SONY: ICF-CS20BT” does not appear on the device’s display, repeat from
step 1.
Note
Some devices cannot display a list of detected devices.
4 Select “SONY: ICF-CS20BT” shown in the display of the
BLUETOOTH device.
5 If Passcode* input is required on the display of the
BLUETOOTH device, input “0000.”
The BLUETOOTH connection is established and “ (BLUETOOTH)” in the display
stays on.
* Passcode may be called “Passkey,” “PIN code,” “PIN number,” or “Password.”
Tip
To pair with other BLUETOOTH devices, repeat steps 1 to 5 for each device.
Notes
Pairing mode of the system is canceled after about 5 minutes, and “ (BLUETOOTH)” in the
display flashes slowly. If the pairing mode is canceled while performing this procedure, start
over from step 2.
Passcode of the system is fixed as “0000.” The system cannot be paired with a BLUETOOTH
device whose Passcode is not “0000.”
Once BLUETOOTH devices are paired, there is no need to pair those devices again. However,
in the following cases, you will need to perform the pairing procedure again.
Pairing information is deleted after repair, etc.
The system is paired with 5 or more devices.
The system can be paired with up to 4 BLUETOOTH devices. If a new device is paired after 4
devices have been paired, the device whose latest connection time is the oldest among the
4 paired devices is replaced by the new one.
More than one device can be paired with the system, but sound will be heard from just one
of those devices.
Pattern B
Connecting with a paired BLUETOOTH device
1 Set the BLUETOOTH function of the BLUETOOTH device to
on.
Tips
When BLUETOOTH is pressed, the system tries to establish BLUETOOTH connection
with the BLUETOOTH device connected to the system last time. The BLUETOOTH
connection is established and “
(BLUETOOTH)” in the display stays on.
When “
(BLUETOOTH)” lights up in the display, the system is connected to a BLUETOOTH
device. When you want to connect another BLUETOOTH device, terminate the current
BLUETOOTH connection first by operating the connected BLUETOOTH device.
2 Select “SONY: ICF-CS20BT” shown in the display of the
BLUETOOTH device.
If necessary, select a BLUETOOTH profile that the system supports from the
following: A2DP, HSP or HFP. For details on each profile, see “Listening to
Music by BLUETOOTH Connection with a Smartphone, etc.” or “Using
Hands-free Calling While Listening to Music.”
Note
This step may not be necessary for some devices.
The BLUETOOTH connection is established and “ (BLUETOOTH)” in the display
stays on.
Pattern C
Connecting with a smartphone by One touch (NFC)
By just touching the system with an NFC compatible smartphone, the system
pairs and connects with the smartphone. (After making the BLUETOOTH
connection, the system switches to the BLUETOOTH function automatically.)
