TESTING STORED EMERGENCY NUMBERS

If you store an emergency service’s number (police department, fire department, ambulance) and you want to test the stored number, make the test call during the late evening or early morning to avoid peak demand periods. Remain on the line to explain the reason for your call.

MESSAGE WAITING

If you subscribe to a message waiting service with your local telephone company, the STATUS/MESSAGE indicator flashes and MESSAGE WAITING appears when you have a new mes- sage waiting. The indicator continues flashing until you listen to all of your messages, then MSG WAITING OFF appears for about 5 seconds.

Note: When you are using the phone and there is a message waiting, the STATUS/MESSAGE indicator flashes to let you know there is a message waiting. MESSAGE WAITING does not appear.

ˆCaller ID Operation

If you subscribe to Caller ID service from your phone company, the system automatically displays information about calls you receive and stores the information in Caller ID memory. The system can store up to 40 number records (the most recent is 40), then replaces the oldest call with each new one.
