Notes
• The LINE 1 or LINE 2 button on the base phone double flashes in succession
and the display on the base phone shows “HANDSET IN USE”, when the
handset is used. If you press (LINE 1) or (LINE 2) whichever button is
flashing, you can talk to the handset and to the line connected.
• When the talk time 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.
