FCC Information
The REN is used to determine the number of devices that may be connected to a 
telephone line. Excessive RENs on a telephone line may result in the devices not 
ringing in response to an incoming call. In most but not 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. [For products approved after July 23, 2001, the REN for this product is part 
of the product identifier that has the format US:T7HIP06B8015. The digits 
represented by ## are the REN without a decimal point (e.g., 06 is a REN of 0.6). For 
earlier products, the REN is separately shown on the label.]
If this equipment MBU 400 causes harm to the telephone network, the telephone 
company will notify you in advance that temporary discontinuance of service may be 
required. But if advance notice isn’t practical, the telephone company will notify the 
customer as soon as possible. Also, you will be advised of your right to file a 
complaint with the FCC if you believe it is necessary.
The telephone company may make changes in its facilities, equipment, operations or 
procedures that could affect the operation of the equipment. If this happens the

modifications to maintain uninterrupted service.
