BT SECURITY FEATURES
On the BT system, it is possible to set a (configurable) PIN code to authenti-
cate/connect BT devices, and encrypt the 
data.
The BT PIN code can be enabled and confi
gured by reading the bar codes in 
the following sections.
If you are using a BT scanner directly connected to a host through a BT 
dongle,  verify that the scanner and the BT driver used by the dongle share 
the same PIN code and the same security level. Otherwise the connection 
cannot be established.
Follow these steps to set the PIN code for a scanner:
1. Enable BT Security Mode  by scanning the “Enable” bar code below.
2. Sel
ect a PIN code length of either 4 or 16 characters by scanning the 
appropriate bar code in "Select PIN Code Length" on pa
ge 260.
3. Scan the relevant bar code from "Set PIN Code" on page 260, then scan 
the desired alphanumeric characte
rs from the keypad in Appendix D, 
Keypad to set the PIN code.
See page 304 in “References” for more detailed information and examples 
for this feature.

Changing the security mode setting will unlink the devices. If the Automatic 
Configuration Update is set to the default “Enabled” setting, the devices must 
only be relinked. If the Automatic Configuration Update is set to “Disabled,” 
the Security Mode setting must also be updated in the Base Station using 
Aladdin. After the Base Station has been updated, the devices must be 
relinked.
