• The touch panel handset offers a new experience in telephone
communication. This Touch Sensitive Keypad technology is very
sensitive and may take a little time to get used to. To avoid accidental
key contact while talking, first lift the handset to touch your ear,
pause a brief moment, and then move the lower portion of the phone
closer to your mouth.
• The keypad will automatically disable when the receiver first touches
your ear. This feature reduces the risk of accidental keypad activation
while the phone is held against the side of your face.
• To properly use your Touch phone, pick it up from the back and sides
and cradle it in your hand. While talking, avoid touching the keypad
area unnecessarily to prevent accidental triggering of the keypad.
