Storing/Chain Dialing Service Numbers

You can make a call using more than one of the ET-545’s memory locations. This is called chain dialing. Chain dial- ing is useful for dialing special services such as alternate long distance or bank-by-phone.

When storing numbers for special ser- vices, store the service’s main phone number in one memory location and numbers for additional information in other memory locations.

When calling special services, dial the service’s main number first. Then, at the appropriate place in the call, press MEMORY and the memory location number for the additional information.

Testing Stored

Emergency Numbers

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