Interference
If the sound quality gets worse as you move around while on a call, this is probably caused by
interference between the handset and the base unit, perhaps because you are too near to another
phone or other electrical equipment.
Move to a different position to clear the interference. If you do not move, it might cause a short break
or your call may be cut off.
"Out of range" warning
If you hear a warning tone during a call, or the sound in the earpiece becomes faint or distorted,
you may be going out of range of the base unit.
Move nearer to the base unit within 20 seconds, until the earpiece sound improves. Otherwise,
your call may be cut off.
