To set up and use your AD300 analyzer or MD300 monitor:
1. Install the sensor.
2. Install the batteries.
3. Calibrate the unit.
4. Set the alarms (MD300 only).
The control keys are designed for easy operation. A LOCK/UNLOCK

accidental touching or bumping of the keys. To further reduce the possibly of
incorrect adjustments at least two keys must be pressed in order to modify a
critical calibration or alarm set point value.
Note: The ALARM SILENCE () and BATT TEST key continue
to operate normally when the lock feature is activated.

sensor for damage or electrolyte leakage. If the sensor is

as it may damage the unit.
