Note
Even when you set the ringer volume on the base phone to off, the cordless
handset will ring when the ringer volume on the cordless handset is set to high
or low.
Tips
• To inform you of an incoming call, the display shows “** RINGING **”
even when you set the ringer volume on the base phone to off.
• You can switch between phone conversations via the handset and those via
the speakerphone, simply by picking up the handset while talking over the
speakerphone, or by pressing (SPEAKERPHONE) while talking over the
handset.
