Set-up Tips:

• All amplified phones are sensitive to power surges. Protect the phone by plugging it and the phone line into a surge suppressor. A battery back-up unit (UPS) with surge suppressor will protect the phone and keep it running temporarily during any power outage.
• If you are using a DSL phone line, a second high frequency filter may need to be attached to the phone line to remove the background noise caused by the modem.
