B. General

The 920 Hand Held Pulse Oximeter is portable and is intended for

attended patient monitoring by trained personnel. It displays

numerical values for oxygen saturation and pulse rate. Because the

920 Pulse Oximeter has no patient alarms, the user must frequently

observe the SpO

and Pulse Rate displays.

1. Connecting the Sensors

Connect the sensor to its 9-pin mating jack on the top of the 920 as

shown in Figure II. To select a sensor type, refer to Section VI (A). If

additional cable length is necessary, connect the Model 927 Patient

Cable between the sensor and the 920 Pulse Oximeter. Position the

appropriate sensor on the patient. Refer to Section VI for sensor

positioning information.

2. Turning on the Pulse Oximeter

Turn on the 920 Hand Held Pulse Oximeter by depressing the “”

button on the front of the pulse oximeter. Refer to Figure III.

When the 920 is powered on, the SpO

and ♥ displays will cycle

through the following sequence before displaying valid data values:

• “888 888”

• time saved in memory in hours and minutes

• software revision number

• “- -”
