Remedy
• Make sure the telephone line cord is securely
connected to the telephone outlet.
• Make sure the dial mode is set correctly (page 10).
• Make sure the last dialed number is really the one you
want to dial.
• Make sure your area code is entered.
• Make sure the number you last dialed (including the
tone and pause digits, if used) does not exceed 32
digits.
• The number you last dialed is erased.
• Use the SPEAKER VOLUME control on the phone to
increase the speaker volume.
• Set the RINGER LEVEL switches to H or L (page 14).
• When you pick up the handset, the NEW CALL/
MESSAGES lamp may not flash if the phone is located
near noise sources. Due to the MIC on the handset
picks up the noises, the phone cannot recognize the
tone of the visual message service. In this case, follow
the ways written below:
- Away the phone from noise sources.
- Use the speakerphone on the phone instead of the
handset.
• Make sure you follow the procedure for storing the
number correctly (page 19).
• Make sure the number (including the tone and pause
digits) does not exceed 20 digits.
• Make sure your area code is entered.
• You have pressed a one-touch dial button for which
no phone number has been stored.
• Store the correct number (page 19).
