Headset base and handset lifter installation
Cord labels
The cords provided with your headset have colored labels
attached to help you plug them into the headset base. The back
of the headset base has colored dots above the jacks, and the
names of the jacks on the rear bottom piece of the headset base
corresponding to the colored labels on the cords.
If you are using installation option 1, you can attach the
provided light blue colored label to the end of the curly handset
cord of your telephone that you plug into the headset base.
Digital subscriber line (DSL)
If you subscribe to high-speed Internet service (DSL - digital
subscriber line) through your telephone line, you must install a
DSL filter between the telephone base and the telephone wall
jack. The filter prevents noise and caller ID problems caused by
DSL interference. Please contact your DSL service provider for
more information about DSL filters.

Headset base and handset lifter installation
Installation options
You have three installation options:
Option 1: Connect the handset lifter to a corded phone (pages
23). This option enables you to answer calls even if you
are away from the telephone base.
For this option, you can use the headset with a single
line or multiple line corded telephone (such as the AT&T
1080, 1070 or 1040) or a digital business system (such
as a proprietary PBX telephone system). The handset
lifter (lifter) works with the cordless headset to provide
a complete communication solution for most corded
telephones. The lifter raises and lowers its switch hook
presser to answer, make and end phone calls. The ring
detector provides an incoming call indication through
the cordless headset, so you can answer calls even
when you are away from the telephone base.
Option 2: Connect the headset to a telephone wall jack (page
This option enables you to use the headset with a single
telephone line with or without a telephone.
Option 3: Connect the headset to a corded or cordless telephone
(page
25). You can use the provided line splitter to
connect the headset to a telephone.

Headset base and handset lifter installation
Option 1: Connect the handset lifter to a corded phone
1. Unplug the curly handset cord from the telephone and plug
it into the CURLY CORD jack (light blue dot) on the
headset base.
2. Plug one end of the telephone line cord (provided with the
headset base) into the base handset jack on the telephone
where the curly handset cord was originally plugged in.
3. Plug the other end of the line cord into the BASE JACK
(orange dot) on the headset base.
4. Plug the lifter control cable into the jack of the base adapter.
5. Plug the other end of the base adapter into the LIFTER jack
(blue dot) on the headset base.
Adjust the corded handset audio (see
handset lifter to your telephone. See page 18 to attach the handset
lifter. Make sure the headset base mode is set to LIFTER MODE.

Attach the lifter
1. To choose where to install the lifter
on your telephone, look at the space
underneath the corded handset. If there
is a speaker, the lifter should be centered
over the speaker. If there is no speaker,
the lifter should be centered within the
space. Make sure the lifter arm is raised
above the switch hook of the telephone base.
2. Peel off the protective strips from the
adhesive tape at the bottom of the lifter.

2. Turn the switch hook presser adjustment
knob until the switch hook presser is just
above the switch hook.
3. Lower the lifter arm until the switch hook
presser holds the switch hook down.
4. Place the corded handset on the lifter.
5. Press ON/OFF on the headset. The switch
hook presser should rise and release the

handset is on the lifter. When the switch
hook is fully released, you will hear a dial
tone from the headset.
It may take some adjustments and testing to
find the right position for the lifter. For the
lifter to work properly, the switch hook must
release completely when you press ON/

Headset base and handset lifter installation
Installation of large lifter pad (optional)
If the small lifter pad cannot hold the corded handset steadily, you
can attach a large lifter pad (provided) to enlarge the contact area.
1. Hold the large lifter pad in front of the small lifter pad as
shown below.
2. Insert the large lifter pad into the two front gaps of the small
lifter pad.
Installation of anti-slip pad (optional)
The anti-slip pad (provided) helps prevent your corded handset
from slipping from the lifter.
1. Choose an appropriate position for the anti-slip pad above the
small lifter pad.
2. Peel off the protective strip from the anti-slip pad.
3. Carefully stick the anti-slip pad to your chosen position. You
may now place the corded handset back onto the lifter.

About internal and auxiliary ring detectors
The internal or auxiliary ring detector detects the telephone
ringer and sends a ring tone to the headset earpiece.
If you installed the lifter over the top of the corded phone
speaker, the internal ring detector will recognize when the
phone rings. However, if your corded phone speaker is located
elsewhere on the phone, stick the auxiliary ring detector to the
speaker as shown below.
Install the auxiliary ring detector
1. Insert the auxiliary ring detector plug into the RING DETECT
jack on the lifter.
2. Remove the protective strip from the adhesive tape on the
auxiliary ring detector.
3. Stick the auxiliary ring detector to the center of the corded
phone speaker.
