Blurred or Distorted EnSURE Touch Screens

Introduction

The EnSURE Touch has an electrical component that handles the communication between the system and the screen.  This component is sensitive to electromagnetic frequencies, like radio waves and wireless communication signals.  The performance of the component can also be impacted when the internal plastic components that mount the electronics in the instrument become damaged.

When the instrument displays a blurred, pixelated screen, this likely due to RF interference.  The electrical components in the EnSURE Touch are susceptible to radio frequencies ranging from 100MHz to 500MHz.  When RF waves are introduced to the instruments in proximity (i.e. radio or walkie talkie is activated near the instrument), the signals interfere with the communication between the hardware and the screen becomes blurred.  If this problem is occurring on your instrument, see the solutions section for instructions on how to correct the issue.

When the instrument displays a blue or green distorted display, this is likely due to damage to the instrument.

Solutions

  1. Press the power button to turn off the display.
  2. Remove any sources of RF interference like walkie talkies or other radios within proximity of the instrument.
  3. Press the power button to turn on the display.
  4. If the screen remains blurry there may be other sources of RF interference. Try moving to another location where there are no RF signals and repeat this process.
