Basics Making calls through the speakerphone Press (LINE 1) or (LINE 2) on the base phone. "SPEAKERPHONE" appears on the display and the display also shows the talk time in hours, minutes and seconds. The corresponding line button lights up. Dial the phone number. To adjust the speaker volume, press (VOLUME)(+) or (--). Each press of (VOLUME)(+) or (--) switches the speaker volume by one of 8 levels. To mute your voice, press (MUTING) to disable the microphone. The MUTING lamp lights up. Press (MUTING) again to cancel. When you're done talking, press (OFF). (MUTING) MUTING lamp (VOLUME) (REDIAL/PAUSE) (LINE 1) (LINE 2) (OFF) 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. continued Basics 27US
