Notes
• While conversing with an outside caller via the handset, the display on the
base phone shows "HANDSET IN USE" and you cannot make a call
through the speakerphone. If you press (SPEAKERPHONE), you will hear a
busy tone.
• When the operation duration exceeds 9:59'59, the display counts from 0:00'00
again.
To obtain the best speakerphone performance
• You may not be able to hear the other party's voice in a noisy place.
Therefore, use the speakerphone in a quiet room.
• Do not bring your hand or other object too close to the microphone
or you will hear a shrill noise ("feedback").
• When the speaker volume is loud, or the base phone has been placed
close to a wall, you may find that the volume drops suddenly. This
is due to a circuit in the telephone designed to protect against
feedback. In such cases, lower the speaker volume slightly.
