1-8 Specifications and Safety Information
Multiple base and handset units should not be closer than 20 feet (6m) at any
time.
Radio interference causes interruptions in conversation. When this happens, your
unit is not defective. When noise continues, move to a different location while you
talk. (You might even need to move the base unit.) When the situation persists,
contact the National Technical Assistance Center (NTAC).
