43-473.fm Page 3 Friday, August 13, 1999 9:21 AM READ THIS BEFORE INSTALLATION Each device that you connect to the phone line draws power from the phone line. We refer to this power draw as the device's ringer equivalence number, or REN. The REN is on the bottom of your telephone cassette recorder. If you are using more than one device on the line, add up all the RENs. If the total is more than five, your phone might not ring and your telephone cassette recorder might not record. In rural areas, a total REN of three might impair ringer operation. If ringer operation is impaired, disconnect one of the devices from the line. FCC STATEMENT Your telephone cassette recorder complies with Part 68 of FCC Rules. You must, upon request, provide the FCC registration number and the REN to your phone company. Both numbers are on the bottom of your telephone cassette recorder. Note: You must not connect your telephone cassette recorder to: • coin-operated systems • party-line systems • most electronic key phone systems Warning: To reduce the risk of fire or shock hazard, do not expose this product to rain or moisture.
