Software 4.1

Overview

4.1.1

The Radical-7 product is configured to allow software downloads directly from a PC. The Radical-7 product has three different boards that utilize software that may require upgrade. The Pulse Oximeter Board, Handheld System Board and Docking Station System Board all operate with software that is independent of each other. The software must be compatible between the boards for the Radical-7 product to operate properly. The boards communicate with each other through on board connections - in the case of the Oximeter Board to Handheld System Board. For the Handheld to Docking Station communication, this is accomplished through a Contact Pin/Interface Cable.

4.1.2

When software upgrades are affected, it is imperative that FRM-1312 is completed and returned to Masimo to ensure each unit is tracked with the software version of each unit. This form can be found in this manual, in the contents of the software disk and can also be acquired from Masimo if necessary by contacting Masimo using the information in Section 7.2.4.
