CDC STATEMENT
Items (b) and (d) can be found on the unit’s FCC label. The ringer equivalence number (REN) is used
to determine how many devices can be connected to your telephone line. In most areas, the sum of the
RENs of all devices on any one line should not exceed five (5.0). If too many devices are attached, they
may not ring properly.
6. In the event of an equipment malfunction, all repairs should be performed by your supplier or an
authorized agent. It is the responsibility of users requiring service to report the need for service to the
supplier or to an authorized agent.
CERTIFICATION NOTICE FOR EQUIPMENT USED IN CANADA
The Canadian Department of Communications label identifies certified equipment. This certification means
that the equipment meets certain telecommunications-network protective, operation, and safety
requirements. The Department does not guarantee the equipment will operate to the user’s satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of
the local telecommunications company. The equipment must also be installed using an acceptable method of
connection. In some cases, the company’s inside wiring associated with a single-line individual service may be
extended by means of a certified connector assembly (extension cord). The customer should be aware that
compliance with the above conditions may not prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian maintenance facility—in this case,
your supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions,
may give the telecommunications company cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground connections of the power utility,
telephone lines, and internal metallic water pipe system, if present, are connected together. This precaution
may be particularly important in rural areas.

as when you used the handset.
Adjust the switch marked 1-8 on
the rear of the base as follows:
Adjust position from 1 to 8
(1 is softest, 8 is loudest) by
first talking in the handset
and then in the headset for
each position. When the
person hears no difference
when you talk into the
handset or headset, you
have the correct setting.
(Most settings will be
between 5-7.) If the best
setting is 7 or 8, move the A-
G switch to position G
(Figure 3-8).

CHAPTER 4: Operation
4. Operation
4.1 Using with a Headset
1. Make sure the
headset/handset selector on
top of the base is in the
headset position. Put on the
headset, pick up the
handset, and answer the
phone or make a call.
2. To end the call, put the
handset down.
3. When you answer or make a
call using the headset, the
on-line indicator on the

means the base is
communicating with the
remote (Figure 4-1).
Figure 4-1. On-Line Indicator Flashing.
4. To move away from your
desk during the call, remove
the remote from the base
and clip it to your belt or
put it in your pocket. You
can now move freely up to
200 feet away from the base.
If you move out of
transmission range, you will
hear a double beep in your
headset every 10 seconds.
4.2 Using with a Handset
1. Make sure the headset/
handset selector on top of
the base is in the handset
position.
2. Pick up the handset to
answer the phone or make a
call as usual.
3. To end the call, put down
the handset.
4.3 Using the Pocket and Belt Clips
1. The remote ships with the
pocket clip installed. To use,
slide the wire clip behind
the fabric of your pocket.
2. To use the belt clip, first

CHAPTER 4: Operation
the mute function is on, you can
still hear the other party.
Figure 4-5. Muting the Microphone.
4.6 Recharging the Battery
To ensure optimum battery life,
place the remote in the base when
not in use. The recharging
indicator on the base, marked
with the 5icon, automatically
lights up while the battery is in the
base. It takes 3 hours to fully
recharge the battery. A fully
charged battery provides 12 hours
of continuous talktime. If the
battery power gets too low, you’ll
hear a beep in your headset every
20 seconds. When charging the
battery overnight, put the system
in handset mode (Figure 4-6).
An optional second battery can
charge in the base while the
remote is in use, thus allowing
24-hours-a-day, seven-days-a-week
talktime. To replace the battery,
press the button on the back of
the battery and pull.
