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.
ˎ ˎ Both the system and the device are placed within 1 m (3 ft) of each other.
ˎ ˎ The system is connected to a power source.
ˎ ˎ 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.

ˎ ˎ 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
ˎ ˎ 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
ˎ ˎ To pair with other BLUETOOTH devices, repeat steps 1 to 5 for each device.
Notes
ˎ ˎ 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.
ˎ ˎ Passcode of the system is fixed as “0000.” The system cannot be paired with a BLUETOOTH
device whose Passcode is not “0000.”
ˎ ˎ 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.
ˎ ˋPairing information is deleted after repair, etc.
ˎ ˋThe 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.
ˎ ˎ 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
ˎ ˎ 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.
ˎ ˎ 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.”
