When a brush is used for cleaning the transducer, use only a soft brush; 
coarse/stiff-bristle brushes may cause transducer damage. 
  Keep the control handle and transducer connector out of any cleaning or 
disinfection solutions. The control handle and cable may be cleaned with a 
damp cloth, but only the distal end of the probe up to the 100cm (for adult)/70 
cm (for pediatric) marker on the shaft may be placed into a disinfection 
solution. 
  During immersion disinfection, never immerse the transducers longer than the 
specific time recommended by the disinfection manufacturer. Damage may 
occur to the transducer housing and/or components if disinfection times 
exceed these recommended limits. 
 
Precautions – Panoramic Imaging 
  Measurements on a panoramic image are limited in accuracy by the acquisition 
of the image by the user. 
  Measurements out of plane are potentially less accurate. 
  A good B Mode/2D image is important for a high-quality panoramic image. 
 
Precautions – 3D/4D Imaging 
  3D: Measurements out of plane are potentially less accurate due to movement of 
tissue. 
  A good B Mode/2D image is important for a high-quality 3D/4D image. 
 
Precautions - WIRELESS 
  WIRELESS: The Mindray/Zonare Wireless option device is an RF Receiver and 
Transmitter, operating using industry standard 802.11 b/g protocols. Use of the 
wireless option, in the presence of other high energy RF radiating devices may 
interfere with the transmission of data to the network interfaces. 
  WIRELESS: The Mindray/Zonare Wireless option device supports several 
industry standard security protocols and should be enabled to reduce the chance 
of patient data, transmitted over the wireless interface from the possible 
undesired interception of the data. 
  WIRELESS: Data transmission and reception rates are limited to by the 
bandwidth of the user’s network infrastructure. A Quality of Service (QOS) level 
is determined by the number of users on the network, the data being transferred 
by the users, and distance of the Mindray/Zonare system to the wireless access 
point and other factors.
