Pairing operation
You need to perform the operations below the first time you establish a Bluetooth con-
nection for Bluetooth data communication.
1. Detect Bluetooth devices
2. Configure pairing settings
1. Detecting Bluetooth devices
Confirm that Bluetooth is enabled on the host PC before searching for Bluetooth
devices.
This product will show up as "CT-S251_XX"(XX is last 2 digits of unique BD
address.) when it is detected.
Select this product from among the detected devices.
Note: You can search for devices and change the names.
When memory switch MSW13-5 is set to "No Response," nothing is displayed by
device detection.
You can temporarily switch this setting to device detection (detect mode) by opening
the paper cover and holding down the FEED button for two seconds. Detect mode
is exited when the connection between the host PC is terminated.
2. Configuring pairing settings
Normally, selecting the printer during device detection will transition directly to
pairing settings.
CAUTION
Some host PC configurations and models may not transition directly to pairing settings after the
printer is selected during device detection.
The operation required to configure pairing settings depends on whether SSP (secure
simple pairing) is enabled on the host PC.
If SSP is enabled on the host PC, pairing can be achieved without additional opera-
tions.
If SSP is disabled on the host PC, you will be prompted to input a passkey.
Input the passkey as described below.
Passkey
Last four digits of the address on the self test printout (Letters A through F are upper-
case)
Example: If the address is 01:23:45:67:89:AB the passkey is 89AB.
If you delete paring information from the host PC without deleting the corresponding
pairing information on the printer, the printer may not show up if you detect devices
again with the host PC.
To delete printer pairing information, open the paper cover and then hold down the
FEED button for five seconds.
Deleting pairing information on the printer will put the printer into discovery mode.
