You can use the External button to insert
the access code before numbers stored
in the one touch and speed dial memories.
Before entering the number (pages 22-24),
press External, an
display, and continue entering the number

before dialling the number.
To switch dialling mode during a call
If you are using your PaperJet 55E in
PULSE dialling mode, you can change to
TONE mode during a call using the

interactive services such as the BT
Customer Services line on 150.
After pressing the
digits will be dialled in TONE mode. When
you end the call, dialling will revert to
PULSE mode.
