Troubleshooting - IBM -3920 Installation And Operating Manual

TROUBLESHOOTING

No dial tone/phone will not dial out.
• Check that the AC power adapters are plugged into working power outlets.
• Check all telephone cord connections or try another wall jack.
• Make sure the battery is inserted correctly.
• Make sure the handset and base are registered to each other. When they
are not registered together, the handset cannot connect to the phone line to
dial out. See the instructions on page 14, "Initialize the handset to the base."
Can't hear the ring signal.
• Check the ringer volume controls; at the lowest level the ring may not be heard.
While on a call, you hear another call on the line or experience radio
frequency interference.
• Switch channels to a clear channel.
• Check the wiring for bad connections.
• Do not use this phone within 20 feet of a working microwave. Microwaves
produce frequencies in this range which may cause interference. This
interference is normal for all 2.4GHz phones and should not be considered a
product defect.
The caller's name and/or phone number does not appear on the display.
• Make sure you have subscribed to Caller ID service (from local telephone
company).
• Caller ID service may not work when the phone is connected to a Private
Branch Exchange (PBX).
• The call is coming from an area not supplying caller ID data. "Out of Area"
will appear on the display.
• The caller has requested that their phone number be suppressed from Caller
ID service. "Blocked Call" or "No Caller ID Available" will appear on the
display.
• You answered the call before Caller ID data was displayed, which usually
occurs after the second ring.
New Call/Message Waiting Indicator doesn't work properly.
• Make sure you have subscribed to voice mail compatible with "FSK" type
signaling (check with your local phone company). If your voice mail product
from the local phone company does not support "FSK" signaling, you may
use this feature as a New Call Indicator only.

or Pulse.
