SAFETY NOTES
Excessive sound levels can cause permanent hearing
damage.
1. Always adjust the volume to the lowest level before
listening to unknown
transmissions.
2. Use the lowest reasonable level consistent with
hearing safety.
3. Don’t use high sound levels in the earphone to
overcome high ambient sound levels. That is
absolutely foolish! Demand and use high isolation
earphones.
4. Don’t expose your ears to sound levels that cause
them to ring. If your ears do ring after exposure,
think of it as a
that again.
