Important Information

This phone has been tested and found to 
comply with all applicable UL and FCC 
standards.

Important

Cordless phones such as this one require 
AC power to operate. When the AC power is 
off, you cannot dial out or receive incoming 
calls using your phone. To be safe, you 
should also have a phone that does not need 
AC power to operate (not a cordless phone) 
so you can still make and receive calls if 
there is an AC power failure.

When AC power is lost, the phone loses the 
security access-protection code connection 
between the base and the handset. When 
power is restored, put the handset on the 
base briefly to restore this connection.

READ THIS BEFORE 
INSTALLATION

We have designed your phone to conform to 
federal regulations and you can connect it to 
most phone lines. However, each device that 
you connect to the telephone line draws 
power from the line. We refer to this power 
draw as the phone’s ringer equivalence 
number, or REN. The REN is on the bottom 
of your phone.

If you use more than one phone or other 
device on the line, add up all the RENs. If the 
total is more than five (three in rural areas), 
your phones might not ring. If ringer 
operation is impaired, remove one of the 
devices from the line.
