Philips CPWUA054 - Manual (Page 25)

Select ‘ASCII' as your Key Type.This enables you to enter an encryption key
in normal text.
After ‘Key 1’, enter a code in text and numbers that will be hard to guess.
IMPORTANT:
– You need to make a difference between upper case and lower case
characters. I.e.: "SecretCode" is not the same as "secretcode".
– Use 13 characters for 128-bit encryption (e.g. "topsecretcode") and 5
characters for 64-bit encryption (e.g. "my1st").
