FCC and Other Information
If requested by the telephone company, inform them as follows:
Registration No.  ....................................................(found on the bottom of the unit)
Ringer Equivalence  ...........................................................................................0.2B
The particular telephone lines to which the equipment is connected.
This unit must not be connected to a coin operated line.
If you are on a party line, check with your local telephone company.
Ringer Equivalence No. (REN):
The REN is useful in determining the quantity of devices you may connect to your
telephone line and still have all of those devices ring when your telephone number
is called. In most, but not all areas, the sum of the REN’s of all devices connected
to one line should not exceed five (5.0). To be certain of the number of devices
you may connect to your line, as determined by the REN, you should contact your
local telephone company to determine the maximum REN for your calling area. 
In the event terminal equipment causes harm to the telephone network, the telephone
company should notify the customer, if possible, that service may be stopped.
However, where prior notice is impractical, the company may temporarily cease
service providing that they:
(a) Promptly notify the customer.
(b) Give the customer an opportunity to correct the problem with their equipment.
(c) Inform the customer of the right to bring a complaint to the Federal
Communication Commission pursuant to procedures set out in FCC Rules and
Regulations Subpart E of Part 68.
The Telephone Company may make changes in its communications facilities,
equipment, operations or procedures, where such action is reasonably required in
the operation of its business and is not inconsistent with the rules and regulations
in 47 CFR Part 68.
If such changes can be reasonably expected to render any customer terminal
equipment incompatible with telephone company communications facilities, or
require modification or alteration of such terminal equipment, or otherwise materially
affect its use or performance, the customer shall be given adequate notice in writing,
to allow the customer an opportunity to maintain uninterrupted service.
When programming emergency numbers and/or making test calls to emergency
numbers:
1. Remain on the line and briefly explain to the dispatcher the reason for the call
before hanging up.
2. Perform such activities in the off-peak hours, such as early morning hours or
late evenings.
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.
Privacy of communications may not be ensured when using this phone. 
						

							117
Useful Information
For assistance, please call: 1-800-211-PANA(7262) CAUTION:
Any changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate this device.
Note:
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may
cause harmful interference 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, the user is encouraged to
try to correct the interference by one or more of the following measures:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
—Consult the dealer or an experienced radio/TV technician for help.
Some cordless telephones operate at frequencies that may cause interference to
nearby TVs and VCRs. To minimize or prevent such interference, the base of the
cordless telephone should not be placed near or on top of a TV or VCR. If
interference is experienced, move the cordless telephone further away from the
TV or VCR. This will often reduce, or eliminate, interference.
Operating near 2.4GHz electrical appliances may cause interference. Move away
from the electrical appliances.
CAUTION:
To comply with FCC RF exposure requirements, the base unit should be installed
with its antenna located at 20 cm or more from persons and handset should be
carried with the specific belt-clip provided for the handset to ensure compliance.
Other non-tested belt-clips or similar body-worn accessories may not comply,
therefore, should be avoided.
A TIA/EIA-IS-968 compliant telephone cord and modular plug is provided with this
equipment. This equipment is designed to be connected to the telephone network
or premises wiring using a compatible modular jack that is also TIA/EIA-IS-968
compliant.
This equipment is hearing aid compatible as defined by the FCC in 47 CFR
Section 68.316.
When you hold the phone to your ear, noise might be heard in your Hearing Aid.
Some Hearing Aids are not adequately shielded from external RF (radio
frequency) energy. If noise occurs, use an optional headset accessory or the
speakerphone option (if applicable) when using this phone. Consult with your
audiologist or Hearing Aid manufacturer about the availability of Hearing Aids
which provide adequate shielding to RF energy commonly emitted by digital
devices. 
						

							118
FCC and Other Information
•Environment— do not place the unit in a room where the temperature is less
than 5°C (41°F) or greater than 40°C (104°F). Allow 10 cm (4) clearance around
the unit for proper ventilation. Avoid excessive smoke, dust, mechanical vibration,
shock, or direct sunlight.
•Medical —consult the manufacturer of any personal medical devices, such as
pacemakers or hearing aids, to determine if they are adequately shielded from
external RF (radio frequency) energy. (The unit operates in the frequency range of
2400MHz to 2480MHz, and the power output level can range 0.04 to 0.4 watts.) Do
not use the unit in health care facilities if any regulations posted in the area instruct
you not to do so. Hospitals or health care facilities may be using equipment that
could be sensitive to external RF (radio frequency) energy.
•Routine care — wipe the unit with a soft cloth. Do not use benzine, thinner, or
any abrasive powder. When you leave the unit unused for a long period of time,
unplug the AC adaptor from the outlet.
•If there is any trouble — disconnect the unit from the telephone line and connect a
known working phone. If the known working phone operates properly, have your
unit repaired by a Factory Servicenter or other Authorized Servicer. If the known
working phone does not operate properly, consult your telephone company.
