You may receive notifications (on the Lock screen) from time to time that software updates are available. Tap the notification to be directed to the update. Other options to access updates: Tap on Settings > About Tablet >Wireless Update. NOTE: To perform an update, you must be connected to WiFi. 9 Google Play Updates The first time you sign on to Google Play Store, updates will automatically start downloading on to the tablet.The download icon will appear in the status bar at the top left of screen. Installing a new application while multiple apps are downloading will reduce tablet speed and performance. After all downloads and updates have been installed, the tablet will resume normal operating performance. To view the progress of downloads working in the background, swipe down from the top edge of the screen. 10 Touching and Typing To select an item on the screen, simply tap it once with your fingertip. Some items may require you to "double-tap”. To type in to a text field (i .e., when inputting your name , or a web address), tap the text field. The on-screen keyboard will appear, and allow you to type the information you wish to enter. Touch and Hold: Keep your finger on an on-screen item until it glows or activates an alternate menu. Drag: Move an App or object by touching and holding the image, then moving it to the destination. Slide: When there are extra "screens" to the side, slide one or more fingers from one side to another. 11 Connecting to the Internet Wireless Router In order to connect to the internet, you will need the following: A wireless router or an access point with a broadband internet connection. The name of your network (SSID), as well as the password or other credentials, if your network is secure. The wireless router must support WiFi 802.11 a/b/g/n/ac connections. Go to SETTINGS > Network & internet > WiFi Tap on WiFi to activate wireless connectivity. The Tablet will scan for available WiFi networks within range. Secured networks will require a password. Once you have successfully entered your information the tablet will remember your settings. 12 Connecting Bluetooth Your Tablet is compatible with Bluetooth capable devices. Once your tablet searches and finds the Bluetooth device, follow on-screen instructions to initiate the pairing of the device with the Tablet. Add or "pair" a Bluetooth compatible device with your Tablet as follows: 1) Turn on the compatible Bluetooth device and make it discoverable. 2) Open the Settings > Connected devices. 3) Tap on Pair new device to view available devices. 13 Charging Your Tablet It is recommended to fully charge the tablet before first use.

Figure 1 – MVG COMOSAR Dosimetric E field Dipole Probe Length 330 mm Length of Individual Dipoles 2 mm Maximum external diameter 8 mm Probe Tip External Diameter 2.5 mm Distance between dipoles / probe extremity 1 mm 3 MEASUREMENT METHOD The IEEE 1528, OET 65 Bulletin C, CENELEC EN50361 and CEI/IEC 62209 standards provide recommended practices for the probe calibrations, including the performance characteristics of interest and methods by which to assess their affect. All calibrations / measurements performed meet the fore mentioned standards. 3.1 LINEARITY The evaluation of the linearity was done in free space using the waveguide, performing a power sweep to cover the SAR range 0.01W/kg to 100W/kg. COMOSAR E-FIELD PROBE CALIBRATION REPORT Ref: ACR.233.1.17.SATU.A Page: 5/10 This document shall not be reproduced, except in full or in part, without the written approval of MVG. The information contained herein is to be used only for the purpose for which it is submitted and is not to be released in whole or part without written approval of MVG. 3.2 SENSITIVITY The sensitivity factors of the three dipoles were determined using a two step calibration method (air and tissue simulating liquid) using waveguides as outlined in the standards. 3.3 LOWER DETECTION LIMIT The lower detection limit was assessed using the same measurement set up as used for the linearity measurement. The required lower detection limit is 10 mW/kg. 3.4 ISOTROPY The axial isotropy was evaluated by exposing the probe to a reference wave from a standard dipole with the dipole mounted under the flat phantom in the test configuration suggested for system validations and checks. The probe was rotated along its main axis from 0 - 360 degrees in 15 degree steps. The hemispherical isotropy is determined by inserting the probe in a thin plastic box filled with tissue-equivalent liquid, with the plastic box …
