GSM-R user procedures (cab radio Version 2)

9.8.2.6 Option 6- PA Tests

The PA speech test allows you to test the train’s PA system. Two sub menu options are

available:

a) PA Tone Test

This test sets up a repeating tone to allow all PA speakers in the train to be tested by

walking through the train without the need for a second person. This test is used by

maintenance personnel.

b) PA Speech Test

This test allows speech to test the PA as follows:

Connected to PA

Check PA Speech

Once you are satisfied that the PA test has been successful, you can stop the test by

pressing .

 If a PA system is not attached to the cab radio, for example, on trains not used in

Driver Only (DO) passenger service, you will hear a tone and see an error message

(No PA attached) displayed.

9.8.2.7 Option 7 Version Information

Used by maintainers. Provides a sub menu offering options to display various version

information about the radio.

9.8.2.8 Option 8 Fault Log

Used by maintainers. Displays a list of the last 50 fault events.

9.8.2.9 Background testing

As well as the tests above and the automatic self-test during radio power up, the cab radio

often checks itself. It will report any failures immediately on the active display.

Radio failure 01

Radio failure

After selecting “PA Speech Test” in the sub menu,

you can now speak into the handset microphone

and should be heard clearly over the train’s PA

system. You will need a second person to walk

through the train to see that the system is working

correctly.

If a fault relates to a service affecting failure (see

section 9.2.2) the display will show a ‘failure’

message, accompanied by a fault code.
