403592-0000 1- Rev A 1 Part One: About the ESCORT Guardian™ The ESCORT Guardian™ telemetry transmitter is the next generation of wireless point-of-care multi- parameter patient monitoring. The Guardian is capable of providing you with continuous measurement of dual-lead ECG and the addition of the SpO 2 module supports continuous pulse oximetry measurement, either continuously or at intervals. The Guardian unit is worn by the patient, providing free ambulation for your patients. It monitors supported vital signs and transmits that information to ESCORT II series bedside monitors and to the Vision Central Station. Before Using the Guardian Make sure to use the Guardian only when it has been inserted into its clear vinyl pouch. This disposable pouch helps protect the unit from dirt and moisture while at the same time allowing access to the display 403592-0000 1- Rev A 2 and the keys. Place the unit in the pouch (part number 403539-0000) and thread the patient belt (part number 403538-0000) through the loops on the back of the pouch. The belt can then be positioned on the patient however is most practical and comfortable. Both the pouch and the belt are designed to be disposable. Contact MDE to order more, as necessary. Interacting with the Guardian Telemetry Transmitter The ESCORT Guardian™ telemetry transmitter is designed with an easy-to-use interface. There are four keys on the front of the transmitter that you will use to make selections from a series of sequential menus to interact with the Guardian. You indicate which menu options you want to select by touching buttons on the Guardian’s keypad. 403592-0000 1- Rev A 3 To Do This...Touch This...

Powering Up the Guardian 1. Insert a 9 volt (alkaline or lithium) battery into one or both of the battery chambers. Make sure the negative pole (-) is facing up. The negative pole is the larger of the two poles. 2. Once the battery is inserted, the Guardian transmitter will display its power-up menu, which will display for approximately 30 seconds, or until you press a button to initiate a function. 3. The power-up menu will display the currently set transmitter channel and the software version contained in the transmitter. Figure 1-2 depicts what you will see. 403592-0000 1- Rev A 6 Figure 1-1 Guardian Power Up Menu Note: If the channel field contains “ ???” this means that configuration information has been lost and you must reprogram a channel. Refer to “Configuring the Guardian” in Part 5 of this guide for information on how to reprogram the transmitter’s channel. Powering off the Guardian The Guardian’s power remains on as long as a battery is in place in the battery chamber. To power-off the Guardian for long-term storage or non-use, remove the battery. Refer to Part 5 of this guide for instructions on how to use the Guardian’s power stand-by mode.
