HIMS Braille Sense U2 User Manual page 342

To authenticate a service and connect to it, press "Enter" on the service.
Once you have pressed "Enter" on the service, you will hear "Connecting
service." Then, you will hear "PIN code:" You must use ASCII characters
when you type in this edit box. On the Braille display, you will see "PIN
code:" This edit box will only appear when you have pressed enter on a
service that not say "Connected" after the service name. You can exit
the edit box or cancel any text you have typed in by pressing "Space-z
(dots 1-3-5-6)." You will then be returned to the Bluetooth Service List.
If you have typed in a pin code, and have pressed "Enter," you will hear,
"Please wait for authentication." If the remote device is setup correctly,
and has not been set up to allow this device to always connect, then the
remote device will ask for a pin code. If the remote Bluetooth device pin
code matches the pin code that was typed in the Braille Sense U2, then
the service will authenticate. If this occurs, you will hear, "PIN code
authentication accepted." Then, while the service connects, you will hear,
"Please wait. Access permission." If the remote Bluetooth device does
not give access permission, then you will hear, "Connection failed," and
you will be returned to the Bluetooth Services List. If the remote
Bluetooth device gives you access permission, then the Braille Sense
U2 will say "Connection succeeded." If the connection succeeds, then
you will see "Connected" after the services that have successfully
connected. Some of the service may be connected without inputting pin
code depending on the Remote Bluetooth device settings.
After you have connected to a service, you can press "Enter-d (dots 1-4-
5)" to disconnect the service, and the Braille Sense U2 will say "Service
disconnected." You will then be returned to the Bluetooth Service List. If
you disconnect a service, "Connected" will disappear from the Bluetooth
Service List.
If you connect to the FTP service, you will see a list of files and folders
that are on the remote Bluetooth device. The rest of this chapter will
discuss each service in detail.
