Monitoring Turning the Oximeter On & Off 1. Press the power switch to turn the oximeter on (Fig. 1). 2. To turn off the monitor press and hold the power switch for 1 second. Note: Keeping the FORE-SIGHT ELITE oximeter power cord connected to a power receptacle will assure a full battery charge in the event of a power loss. Start Monitoring 1. Connect the Preamp cable into the oximeter port (Fig. 2). Note: Align the red marks before inserting the Preamp in the port. 2. Apply the Sensor to the patient. Refer to Applying the Sensor (Figs. 4-6). 3. Connect the Sensor to the Preamp (Fig. 7). Configuring the Sensor Location & Alarms 1. To access the Patient Setup screen: a. Touch a numeric or body icon in Channel Numeric area. b. From the Main Menu, touch Patient and then touch Patient Setup. 2. Touch the body icon (in the Loc column) to select the Sensor location (Fig. 3). 3. Touch the button for the channel limit you wish to modify (Fig. 3). 4. Use the keypad to enter the new value. 5. Touch Accept to save your changes. Starting a New Case From the Main Menu, touch Patient and then touch New Patient. Fig. 1 Fig. 2 Fig. 3
Sensor Selection Sensor Size LARGE P/N 01-07-2103 Applying the Sensor Patient Weight 40 kg ( 88 lbs) 1. Remove the Sensor and alcohol pad from the package. 2. Clean the skin and let it dry (Fig. 4). 3. Remove protective liner from the Sensor (Fig. 5). 4. Apply Sensor to patient (Fig. 6). a. Cerebral use - frontal lobe: above each eyebrow and just below the hairline. 5. Insert the Sensor connector into the Preamp Sensor connector until it snaps into place (Fig. 7). Note: For further instructions on how to begin monitoring, consult the User Manual. Please view the warnings and cautions in the Sensor Directions for Use. Silencing Alarms To silence the audible alarm for two minutes, touch Silence. Visual alarms will remain active. Fig. 4 Fig.5 Fig. 6 Fig. 7
