INTRODUCTION
The RadioShack Automatic Two-Line Adapter lets you use
any single-line touch-tone telephone with two-line telephone
service. The adapter lets you make calls on either line, and
put a call on hold while making a second call or answering a
second line.
Its other features include:
Automatic Operation — automatically selects a free line
when the phone is taken off the hook, and selects the ringing
line when a call comes in.
Manual Operation — lets you manually select and hold ei-
ther line.
Hold — holds a line then automatically hangs up after 3 min-
utes, 30 seconds to avoid tying up the unattended line.
Music On Hold — plays music (Beethoven’s
Fur Elise
) for
the other party when the line is on hold.

Distinctive Tones — alert you when batteries (if used) are
low or there is an incoming call on the other line.
Note: You must have two-line telephone service to use all the
features of this adapter. This adapter does not give you a
second telephone line. Only the telephone company can pro-
vide you with an additional line.
This symbol is intended to inform you that important op-
erating and maintenance instructions are included in the

READ THIS BEFORE INSTALLATION
We have designed your Two-Line Adapter to conform to fed-
eral regulations, and you can connect it to most telephone
lines. However, each device that you connect 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 shown on the bottom of your adapter).
!

If you are using more than one phone or other device on the
line, add up all the RENs. If the total is more than five, your
phones might not ring. In rural areas, a total REN of three
might impair ringer operation. If ringer operation is impaired,
disconnect one of the devices from the line.
FCC STATEMENT
This device complies with Part 68 of
FCC Rules
. You must,
upon request, provide the FCC registration number and the
REN to your phone company. These numbers are located on
the bottom of your adapter.
Note: You must not connect your Two-Line Adapter to any of
the following:
• Coin-operated systems
• Party-line systems
• Most electronic key telephone systems

INSTALLATION
INSTALLING THE ADAPTER
Connect the adapter to any RJ14 two-line modular jack using
the supplied four-conductor modular telephone cord.
Plug the telephone cord into the adapter’s LINE jack.
Plug the remaining end of the telecord into an RJ14C modu-
lar telephone jack. If you have two separate RJ11 single-line
modular jacks, you can use a Two-Line Coupler (Cat. No.
279-401).
Your telephone connects directly to a modular telephone line
jack. If your telephone wiring does not have a modular jack,
you can update the wiring yourself or have the telephone
company update it for you.
• RadioShack stores sell jacks and adapters to convert
older wiring methods to modular wiring.

• The telephone company charges to install the necessary
jacks.
• The USOC number of the jack to be installed is RJ14C
(or RJ14W for a wall plate jack).
• After you install the adapter, check to be sure there is a
dial tone. If there is not, disconnect the cords and re-
install the adapter.
POWERING THE ADAPTER
You can power the adapter from internal batteries or stan-
dard AC power (using an optional AC adapter).
Note: Connecting an optional adapter disconnects internal
batteries.
Using Batteries
Your adapter can use six AA batteries (not supplied) for pow-
er. We recommend alkaline batteries, such as RadioShack
Cat. No. 23-552.

Follow these steps to install the batteries.
1. Use a Phillips screwdriver to remove the screw from the
battery compartment cover, then remove the cover.
2. Insert six fresh batteries into the compartment, as indi-
cated by the polarity symbols (+ and –) marked inside
the compartment.
3. Replace the cover and the screw.
Notes:
• If the adapter sounds three beeps each time you pick up
a connected phone, replace the batteries.

• The POWER indicator does not light if the two-line
adapter is powered by internal batteries.
Using AC Power
To power the adapter from an AC outlet, you need an AC
adapter (not supplied), such as Cat. No. 273-1455.
Cautions:
• You must use a Class II AC adapter that supplies 9 volts
and delivers at least 100 milliamps. Its center tip must be
set to negative, and its plug must correctly fit the DC 9V
jack on the two-line adapter. The recommended AC
adapter meets these specifications. Using an AC
adapter that does not meet these specifications could
seriously damage the two-line adapter or the AC
adapter.
• Always plug the AC adapter into the two-line adapter
before you plug it into the AC outlet, and unplug the AC
adapter from the AC outlet before you unplug its barrel
plug from the two-line adapter.

Follow these steps to connect an AC adapter to the two-line
adapter.
1. Insert the AC adapter’s barrel plug into the adapter’s DC
9V jack.
2. Plug the AC adapter into a standard AC power outlet.
The POWER indicator lights.

OPERATION
You can make outgoing calls on either telephone line.
When you pick up the connected phone’s handset, the IN
USE indicator lights steadily and line 1 is automatically se-
lected unless it is currently in use. To select the other line,
press # twice. The indicator turns off within a few seconds af-
ter you hang up.
USING THE CALL ALERT SWITCH
If you set the switch inside the battery compartment to CALL
ALERT, the phone sounds three beeps when the other line
rings while you are on the phone.
Note: If a line is in use at another telephone extension, that
line gives the caller a busy signal unless you have line roll-
over.
