FCC Information 
We designed your telephone signaler to conform to federal 
regulations, and you can connect it to most phone lines.  
However, each TR55 (and other device, such as a phone or 
answering machine) you connect to the phone line draws 
power.  We refer to this power draw as the ringer equivalence 
number, or REN.  The REN is on the TR55 rating label. 
If you use more than one phone or other device on the phone 
lines, add up all the REN’s.  If the total is more than five, 
Phones might not ring.  In rural areas, a total of three might 
impair ringer operation.  If ringer operation is impaired, 
disconnect a device from the line. 
Your TR55 complies with Part 68 of FCC Rules.  You must, 
upon request, provide the FCC registration number and the 
REN to your local phone company.  Both numbers are shown 
on the TR55’s rating label. 
In the unlikely event that your TR55 causes problems on the 
phone line, the phone company can temporarily discontinue 
service.  If this happens, the phone company notifies you of 
these changes in advance.  If advance notice is not practical, 
the phone company notifies you as soon as possible and advises 
you of your right to file a complaint with the FCC. 
Also, the phone company can make changes to its lines, 
equipment,  or procedures that could affect the operation of this 
device.  The phone company notifies you of these changes in 
advance, so you can take the necessary steps to prevent 
interruption of your phone service. 
Modifying or tampering with your TR55’s internal components 
can cause a malfunction and invalidate the TR55’ warranty and 
void your FCC authorization to operation it.  If the TR55 is not 
operating as it should, return it to Sonic Alert.  If the problem is 
harming the phone lines, the phone company might ask that 
you disconnect the TR55 until the problem is resolved.
