Important Safety
Instructions
When using your telephone equipment, always follow
basic safety precautions to reduce the risk of fire, electric
shock, and injury to persons, including the following:
1. Read and understand all instructions. Observe all
warnings and other markings on the product.
2. During thunderstorms, avoid using telephones except
cordless models. There may be a slight chance of
electric shock from lightning.
3. Do not use a telephone near a gas leak. If you suspect a gas leak, report it immediately, but use a telephone away from the area where gas is leaking.
4. Do not use this product near water, or when you are
wet. For example, do not use it in a wet basement or
shower, or next to a swimming pool, bathtub, kitchen
sink or laundry tub. Do not use liquids or aerosol
sprays for cleaning. If the product comes in contact
with any liquids, unplug any phone line or power cord
immediately. Do not plug the product back in until it
has dried thoroughly.
5. Install this product in a protected location where no
one can trip over any phone line or power cord.
Protect cords from damage or abrasion.
6. If this product does not operate normally, review the
“Troubleshooting” section. If you cannot resolve the
problem, or if the product is damaged, refer to the
Ameriphone Warranty. Do not open this product
except as may be directed in this owner’s manual.
Opening this product or reassembling it incorrectly
may expose you to hazardous voltages or other risks.
Opening this product automatically voids the warranty.
7. If this product uses batteries as power back-up during
power outages, replace batteries only as described in
this owner’s manual. Do not burn or puncture used
batteries — they contain caustic chemicals.
8. Unplug this product from the wall outlet and refer
servicing to qualified service personnel under the following conditions:
A. When the power supply cord or plug is damaged
or frayed.
B. If liquid has been spilled on the product.
C. If the product has been exposed to rain or water.
D. If the product does not operate normally by follow-
ing the operating instructions. Adjust only those
controls that are covered by the operating instruc-
tions because improper adjustment of other con-
trols may result in further damage.
E. If the product has been dropped or appears
damaged.
F. If the product exhibits a distinct change in perfor-
mance.
9. If this product has a polarized plug with one wide
prong, it may not fit in non-polarized outlets. Do not
defeat the purpose of these plugs. If they do not fit in
your outlet, the outlet should be replaced by an
electrician.
ADDITIONAL SAFETY NOTES FOR
CANADIAN USERS
NOTICE: The Canadian Department of Communications
label identifies certified equipment. This certification means
that the equipment meets certain telecommunications network protective, operational and safety requirements. The
Department does not guarantee the equipment will operate
to the user's satisfaction.
Before installing the 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. 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 designated by the supplier. Any repairs or alteration 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.
CAUTION: Users should not attempt to make such connections themselves, but should contact the appropriate electric
inspection authority, or electrician, as soon as possible.
NOTICE: The LOAD NUMBER (LN) assigned to each
terminal device denotes the percentage of the total load to
be connected to a telephone loop which is used by the
device, to prevent overloading. The termination on a loop
may consist of any combination of devices subject only to
the requirement that the sum of the load numbers of all
devices does not exceed 100.
