Unlike analogue broadcasts, each service does not have a proper service number in digital broadcasts. Service numbers are just assigned to the services in the order that they were found in the service search. So you can reassign a service num- ber by moving a service entry. To move a service entry, select the Move option and select a desired service; then the selected
service becomes darker. As you move it up or down, it gets renumbered according to the position. Press the OK button to fix it.
You can lock some services to prevent your children from watching them. To lock a service, select the Lock option and select a desired service; then a lock symbol 
will be marked on the selected service. If anyone tries to watch a locked ser- vice, the person has to enter the personal identification num- ber that is set to the Change PIN Code option. See § 3.4 for this option. To unlock a locked service, press the OK button on it.
To delete a service, select the Delete option and select a de- sired service with the OK button, and then press the EXIT button; you will be asked for confirmation. If you select Yes, the selected service will be deleted. If you want to undo the deleted service, there is nothing you can do but perform a ser- vice search again.
Once you select the Sort option on the left column, sorting options are displayed as follows:
Default by service number
Alphabetic by service name
Satellite by satellite
