READ THIS FIRST
We have designed your TAD-277 to
conform to federal regulations, and
you can connect it to most telephone
lines. However, each device you con-
nect 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 TAD-
277.
RISK OF ELECTRIC SHOCK.
DO NOT OPEN.
CAUTION : TO REDUCE THE RISK OF
ELECTRIC SHOCK, DO NOT REMOVE
COVER OR BACK. NO USER-SERVICE-
ABLE PARTS INSIDE. REFER SERVIC-
ING TO QUALIFIED PERSONNEL.
WARNING: To reduce the risk of
fire or shock hazard, do not ex-
pose this product to rain or mois-
ture.
CAUTION
!
!
If you are using more than one device
on the line, add up all the RENs. If the
total is more than five, your phones
might not ring and your TAD-277
might not answer. In rural areas, a to-
tal REN of three might impair ringer
operation. If ringer operation is im-
paired, remove a device from the tele-
phone line.
FCC STATEMENT

of

bottom of your TAD-277.
