before answering. If external callers are not identified on the display, make sure you subscribe to "Caller ID"
services from your local telephone company. "Caller ID" services may have different names in your
area—contact your local telephone company for details.
2. The headset jack is compatible with a large number of headsets, the recommended M12LUCM modular
base unit, or the HIP-1 headset adapter. Noise canceling headsets are recommended.
