Clarity® Power™ Technology
With Clarity Power, the high frequency sounds are
amplified more than the low frequency sounds so
words are not just louder, but clearer and easier to
understand. It also provides intelligent
amplification to make soft sounds audible, while
keeping loud sounds bearable.
BOOST – Clarity Power On/Off
The C600 has a button that controls the loudness of
the receiver. Once the BOOST button is pressed, an
extra level of amplification is added over the entire
range of the volume control.

WARNING: When the TALK button is lit ORANGE
volume may be at a high level. To protect
hearing, lower the volume control to minimum
before using.
Volume Control
The dial controls the level of volume the handset and
headset receive. The volume dial provides up to 15
dB of volume before the CLARITY POWER button
is activated. Once the CLARITY POWER button is
pressed, the C600 will provide up to 40 dB of ampli-
fication.
Tone Switch
The C600 has three (3) TONE settings. Adjusting the
TONE switch changes the style of amplification and

conversations from being accessed by a phone on
a different line. Once the handset battery is fully
charged, the handset will automatically select the
code from over 65,000 different combinations. The
code is changed every time the handset is placed in
the cradle. If you have trouble with placing or receiv-
ing calls, a lost security code may be the cause of
the problem. When this occurs, the handset can no
longer communicate with the base.

exceed five (5.0). To be certain of the number of de-
vices that may be connected to a line, as determined
by the total RENs, contact the local telephone com-
pany. For products approved after July 23, 2001, the
REN for this product is part of the product identifier
that has the format US:AAAEQ##TXXXX.
The digits represented by ## are the REN without

Part 15 of FCC Rules Information
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation.
Your equipment has been tested and found to
comply with the limits of a Class B digital device,
pursuant to Part 15 of FCC rules. These limits are
designed to provide reasonable protection against
harmful interference in residential installation.
This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in ac-
cordance with the instructions, may cause harmful in-
terference to radio communications. However, there
is no guarantee that interference will not occur in a
particular installation; if this equipment does cause
harmful interference to radio or television reception,
which can be determined by turning the equipment
off and on, you are encouraged to try to correct the
interference by one of the following measures:
1. Where it can be done safely, reorient the
receiving television or radio antenna.
2. To the extent possible, relocate the television,
radio or other receiver with respect to the
telephone equipment. (This increases the
separation between the telephone equipment
and the receiver.)
3. Connect the telephone equipment into an
outlet on a circuit different from that to which
the television, radio, or other receiver is
connected.
4. Consult the dealer or an experienced Radio/
TV Technician for help.
CAUTION: Changes or modifications not ex-
pressly approved by the manufacturer responsible for
compliance could void the user’s authority to oper-
ate the equipment.

above conditions may not prevent degradation of
service in some situations. Repairs to certified equip-
ment should be made by an authorized Canadian

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 util-
ity, telephone lines and internal metallic water pipe
system, if present, are connected together. This pre-
caution may be particularly important in rural areas.
