TOUCH PHONE USE AND HANDLING
• The touch panel handset offers a new experience in telephone communication. This
Touch 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 get the best use out of 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.
• It is very easy to tell when the keypad is disabled, as the keypad backlight will be off.
• To turn keypad backlight on and activate the keypad, touch any of the number keys, wait
for the backlight to come on and then dial normally.
• During a call, the keypad will automatically disable and the backlight will turn off. When
you want to end the call, the first key-press of the key will only wake up the keypad,

8
and a second press of the key will be required to terminate the call.
• When dialing digits, hold the handset away from the LCD area as shown below.
Touching the LCD display may trigger the automatic keypad lock sensor and prevent you
from dialing. If the keypad lock sensor is triggered, a small key will appear in the top left
corner of the display.
