boards and cases and can cause the system to work improperly.
Use only fresh batteries of the required size and recommended type.
Batteries can leak chemicals that damage your system’s electronic
parts.
Wipe the system with a damp c loth occ asional ly t o keep it look ing n ew.
Do not use harsh ch emicals, cleani ng solvents, or str ong detergen ts to
clean the system.
Modifying or tamper ing with the system’s internal c omponents can cause a malfunction and might invalidate its warranty and void yo ur FCC author ization to operate it. If your system is not performing as it should, take it to your local RadioShack
