  Failure to perform certain procedures or note certain conditions may impair the performance of this product. For maximum safety and optimal performance, please read and understand the Ventis MX4 Product Manual available online at the Ventis MX4 Resource Center at www.indsci.com/ VentisMX4resources.

• Page 4: General Usage

  (e.g., iNet Control or Accessory Software) or by manually configuring the instrument settings after docking. The Ventis MX4 is CSA certified according to the Canadian Electrical Code for use in Class I, Division 1 and Class I, Zone 1 Hazardous Locations within an ambient temperature range of T : -20°C to +50°C.

• Page 5: Recommended Practices

  When reassembling the instrument or installing a battery pack, maintain ingress protection by tightening each fastener to its stated torque value (see the “Ventis MX4 Monitor three-Dimensional Diagram” and its key in this manual).

• Page 6: Ventis Mx4 Resources

  Ventis MX4 Resources ► The Ventis MX4 Product Manual is the primary resource, within a full suite of learning tools, developed for the monitor user. Its step-by-step “walk through” format covers everything from unpacking to set-up, operation, and service. All Ventis MX4 users should read and understand the Product Manual prior to unpacking or using the monitor.

• Page 7: Unpacking The Monitor

  (Datalink refers to capabilities that enable access to the download and use of monitor datalogs, reports, and other information.) For a complete list of the Ventis MX4 system of products, please refer to the manual section, Products and Parts.

• Page 8: Monitor Overview

  Ventis™ MX4 Product Manual ►Monitor Overview HARDWARE FEATURES AND FUNCTIONS The monitor’s case top (front of monitor) has two main sections. As shown below, the upper section contains the sensor ports. The lower section houses the user interface features, a LCD display screen and two buttons. Each feature’s general functions are noted below.

• Page 9: Display Screen

  DISPLAY SCREEN The Ventis MX4 Boot-up Screen, as shown below, serves to introduce all icons and the alpha-numeric items (e.g., 8.8.8) that can appear on the display when the monitor is in use, docked, or charging. Each display item is stationary, communicates unique information, and appears only when relevant to the task being performed.
