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).
N
ote: 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).
