 User Guide 

 

 
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 
of the Federal Communication Commission (FCC) Rules. These limits are designed to provide reasonable protection 
against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio 
frequency energy, and if not installed and used in accordance with the instructions, may cause harmful interference 
to radio communications. However, there is no guarantee that interference will not occur in a particular installation. 
If this equipment does cause harmful interference to radio or television reception, which can be determined by 
turning the equipment OFF and ON, the user is encouraged to try to correct the interference by one or more of the 
following measures: 
 
•  Reorient or relocate the receiving antenna. 

•  Increase the separation between the equipment and the receiver. 

•  Connect the equipment to a different circuit from that to which the receiver is connected. 

•  Consult the dealer or an experienced radio/TV technician for help. 
 

 
This equipment (Models 7400, 7401) complies with Part 68 of the FCC rules and the requirements adopted by the 
ACTA. A label on the bottom of this equipment contains, among other information, the Ringer Equivalence Number 
(REN) and the product identifier. For products approved after July 23, 2001 the product identifier is in the format 
US:AAAEQ##TXXXX. The digits represented by ## are the REN without a decimal point (e.g. 03 is a REN of 0.3). 
The REN is used to determine the number of devices that may be connected to a telephone line. For earlier products, 
the REN is separately shown on the label. If requested, this number must be provided to the telephone company. 
 
Excessive RENs on a telephone line may result in the devices not ringing in response to an incoming call. In most, 
but no all areas, the sum of RENs should not exceed five (5.0). To be certain of the number of devices that may be 
connected to a line, as determined by the total RENs, contact the local telephone company. 
 
This equipment is designated to connect to the telephone network or premises wiring using a compatible modular 
jack that is Part 68 compliant. An FCC compliant telephone cord and modular plug is provided with the equipment. 
See the Installation Information section of this User Guide for details.
