Sensor Initialization

After the Transmitter Search is done, the SUCCESS screen will be

briefly displayed. The INIT screen will then appear. The system

automatically initializes the Sensor before starting to record

glucose data. Initialization takes about 120 minutes (2 hours). The

Monitor, however, will count down from 140 minutes (2 hours and

20 minutes) toward 0 hours and 0 minutes, or until finished

(whichever comes first), in one-minute intervals.

Sensor Calibration

When initialization is done, the system will alarm and the Enter

BG screen to the right will be displayed. This screen shows that

calibration is needed. A fingerstick glucose value must be

entered into the Monitor to calibrate the Sensor. The Guardian RT

will not record or display any glucose values, and the High and

Low glucose alerts will not work until calibration is done.

Calibration is needed to make sure the Guardian RT can turn the

electronic signals from the Sensor into glucose values. Make sure

to enter a BG value right after taking a fingerstick glucose reading.

Calibration will happen within 10 to 15 minutes of the Meter BG entry.

NOTE -

Use the same blood glucose meter for all calibrations to ensure the accuracy of the calibrations.

NOTE -

If an incorrect blood glucose value is entered, this value can be overwritten within 10-15

minutes of input.

1. Press the SEL button followed by ACT to clear the alarm.

2. Press the SEL button 2 times. When the METER BG screen appears, the last glucose value (mg/dl or

mmol/l) entered will be displayed. (Dashes will appear the first time since no entry has been made.)
