Clean Heads

• 1). Dip cotton swab in anhydrous isopropyl alcohol and gently scrub heads (these are the parts that read the tape).
  
  
• 2). Dry the heads with the other end of swab.
  
  
• 3). Use fresh swab when one gets visibly dirty.
  
  
• 4). Repeat until the swab does not appear to be discolored.
