Page 1 of Philips 610 (Lower case to Upper Case)

Somehow, when editing titles, i have managed to change the Letters from Upper case to Lower case. Any ideas how to get back to upper case again. The manul is next to usless in telling you how to. Thanks in advance

The select button toggles between upper and lower case. This is mentioned around page 16 of the manual (may depend on the date of the manual) - the first of the two pages each with a figure of the remote and explanation of the buttons.
