PRO-2041 Scanner 
(200-0463)                 Care and Maintenance       Faxback Doc.  # 38902 
 
 
Your Radio Shack PRO -2041 400-Channel Programmable Home Scanner is an  
example of superior design and craftsmanship.   The following suggestions  
will help you care for your scanner so you can enjoy it for years.  
 
  Keep the scanner dry.  If it gets wet, wipe it dry immediately.  
  Liquids can contain minerals that can corrode the electronic circuits.  
 
  Handle the scanner gently and carefully.   Dropping it can damage  
  circuit boards and cases and can cause the scanner to work improperly.  
 
  Use and store the scanner only in normal temperature environments,  
  Temperature extremes can shorten the life of electronic devices and  
  distort or melt plasti c parts. 
 
  Keep the scanner away from dust and dirt, which can cause premature  
  wear of parts. 
 
  Wipe the scanner with a damp cloth occasionally to keep it looking  
  new.  Do not use harsh chemicals, cleaning solvents, or strong  
  detergents to clean th e scanner. 
 
Modifying or tampering with the scanner's internal components can  
cause a malfunction and might invalidate its warranty and void your  
FCC authorization to operate it.   If your scanner is not operating as  
it should, take it to your local Radio S hack store for assistance .
