Getting Started 5
The Touch Screen
The 973 utilizes a touch screen for user interaction. To activate a menu option or toggle a
function on or off, simply touch the screen directly over the key or object desired.
Calibrate the Touch Screen
Before using the 973 for the first time, you may need to calibrate the touch screen to your finger
positioning preference. Here’s how –
1. Press and hold the enter key on the numeric
keypad for 3 or 4 seconds. If you’ve done it
correctly, you’ll hear two loud short beeps.
If not, release the key and try again.
2. With the tip of your finger, press the center
of the yellow key in the upper right corner of
the touch screen. It is labeled ‘Touch This
Key’. Once you touch it, the yellow color
goes away and another key turns yellow.
3. Now, touch the yellow key that’s in the lower
left corner of the touch screen. Once you
touch it, the yellow color goes away and you
have successfully calibrated the touch
screen.
4. Test your new touch screen calibration by pressing each of the six blank menu keys on the
right side of the touch screen several times. If they seem not to work well, just repeat the
calibration steps again from the beginning.
You may recalibrate the touch screen as often as needed, however, it is rarely required.
