Weak or Hard to Hear Audio
If the caller’s voice sounds weak or soft, the signal might be blocked by large metal objects or walls; you might also
be too far from the base, or the handset’s battery may be weak.
Try adjusting the volume of the earpiece (see page 35) or the audio tone (see page 36).
Try moving around while you’re on a call or moving closer to the base to see if the sound gets louder.
Make sure the handset’s battery is fully charged.
