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.
