CALIBRATION UPDATE

You must update the Seven System calibration every 12 hours. The
Receiver will remind you to do this by displaying the following screen if you
haven't recently calibrated.
When the Single Blood Drop Prompt appears, clear
the prompt, take a fingerstick using your meter, and
enter the meter reading into the Receiver.
After you enter a BG reading for calibration the
Receiver may prompt you again by displaying the Single Blood Drop
Prompt Screen (with vibrate/beep, depending on your settings). This
means the last BG reading could not be used for calibration. You will
need to enter one more fingerstick to recalibrate.
CALIBRATION ALERT SCREENS
During calibration you may see the following screens:
1. New Meter Screen (Auto Upload Only):
Indicates you have connected a new One Touch
Ultra meter to the Receiver. This meter has a
different serial number from the meter that was
last connected to the Receiver. Press the
OK button.
If you receive this screen during Auto Upload calibration, your will have
to re-take any fingersticks needed for calibration and then connect the 2
devices again for Calibration Update.

2. Connection Failure (Auto Upload Only):
Indicates the OneTouch meter and the Receiver
are not connected properly. If you see this screen
the meter readings will not be transferred
successfully. Clear the alert by pressing any
button, and disconnect the Connection Cable
from the Receiver. Make sure the meter is off, then reconnect the Cable
to the Receiver (the cable must be plugged into the meter first, as in
Auto Upload Calibration).
3. Double Blood Drop Prompt:
Appears about 2 hours after you insert a new
Sensor and tells you that you need to take 2
fingerstick readings on your meter. Clear the
prompt by pressing any button on the Receiver,
and enter 2 more fingersticks as prompted.
4. Shaded-Out Blood Drop Prompt:
This tells you that only 1 fingerstick reading has
been successfully entered. You need to take and
enter at least 1 more fingerstick for calibration.
Clear the prompt by pressing any button, and
enter 1 more fingerstick as prompted.
GLUCOSE RECORD GAPS

If the System does not display "---"in the Status Box it is not recording
glucose readings. This may be for the following reasons:
1. Awaiting Fingerstick Reading/Blood Drop
in Status Box:
Indicates that you need at least 1 more
fingerstick to calibrate. This symbol will appear
when it is time for the Start-Up Calibration or
Re-Calibration.
