Safety Instructions
Caution: Your wireless telephone gives you freedom and
flexibility to stay in touch while you move around. However, the
safe and responsible use of the phone depends entirely on you.
When using your phone equipment, safety instructions should
be followed to avoid the risksof fire, electric shock, injury to
person, and damage to property.
General Safety Instructions
1. When using your wireless phone, ensure your safety and the
safety of others:
a. Always watch where you are walking and standing.
b. Don’t let a phone call distract you from working safely.
2. In an emergency:
a. If an emergency occurs, dial the emergency phone
number. However, if you are in an area where your phone
does not have a clear signal from the base, it is highly
probable that the call may not go through. Locate the
nearest landline telephone or other communications
devices to call for help.
b. Emergency calls may not automatically provide
emergency personnel with your name, phone number or
location. Tell the operator
i) Your name and phone number
ii) The nature of the emergency
iii) Whether police, fire, or medical assistance is needed
iv) The exact location of the emergency, including
address, cross streets, mileposts or landmarks.
3. Notice to Hearing Aid Users: This phone system is compatible
with inductively coupled hearing aids.
4. Notice to Cardiac Pacemaker Users: Preliminary studies done
by the US FDA and others have shown that, although
interference to the implanted cardiac pacemaker may occur
when operating very closely, wireless telephones “do not
seem to pose a significant problem for pacemaker wearers.”
However, until more is known, FDA suggests that people with
pacemakers may want to take precautions when using or
carrying a wireless telephone to ensure that there is ample
distance between the telephone and the pacemaker. Do not

5
carry the handset in a breast pocket. If you have any reason
to suspect that interference is taking place, turn off your
handset immediately.

Regulatory Information
Model: 25450XXX-A
FCC ID: G9H2-5450A
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.
1. This telephone system complies with rules of the FCC Part 68.
On the bottom of the Base Unit is a label that contains, among
other information, the FCC Registration Number, Ringer
Equivalence Number (REN) and the Universal Service Order
Code, which is RJ-11C in the U.S. Your telephone company
may ask you for this information.
2. The REN is useful to determine the quantity of devices you
may connect to your telephone line and still have all 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 5.0. To be certain of the number
of devices you may connect to your phone line, you should
contact you local telephone company for the maximum REN in
your area.
3. If your telephone equipment causes problems to the telephone
network, the telephone company may ask you to disconnect
your phone system from the line until the problem has been
corrected. Consult with your local phone company for your
rights if this happens.
4. Your telephone company may make changes in its facilities,
equipment, operations, or procedures that could affect the
proper functioning of your telephone system. Consult with
your local phone company for your rights if this happens.
5. This telephone system may not be used on coin service
provided by the telephone company. Connection to party lines
is subject to state tariffs.

9
6. This telephone system has been tested and found to comply
with the limits for Class B digital devices, pursuant to Part 15
of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a
general public installation. Operations of these devices may
still encounter interference from/to nearby TV’s, VCR’s, radios,
computers, or other electronic devices. To minimizeor
prevent such interference, the telephone system should not be
placed or operated near other electronic devices. If
interference occurs, moving the Base Unit and the handset
farther away from them will often reduce or eliminate the
interference.
7. However, there is no guarantee that interference will not occur
in a particular installation. If this telephone system does
cause interference to other electronic devices, which can be
determined by turning the system off and on, the user is
encouraged to try to correct the interference by one or several
of the following measures:
a. Increase the space separation between the handset or
Base Unit and the device that is experiencing interference.
We recommend 20 feet or more between the system and
other electronic devices.
b. Connect the Base Unit to a power outlet on a circuit
separate from that used by the device experiencing
interference.
c. Consult the dealer or an experienced electronic technician
for help.

electronic devices (e.g., TV, computer, stereo, fax
machine, answer machine, etc.)
4. Connecting the Telephone Cords
a. If your telephone lines are of 2-wire, 1-line type known as
RJ-11, plug one end of the phone cord into one of the 4
phone jacks marked L1 –L4 and plug the other end into
the telephone outlet. The RCA 25450 has abuilt-in “Line
Detection”feature; it is okay to plug in the phone jacks in
random order.

21
b. If your telephone lines are of 4-wire, 2-line type known as
RJ-14, you should plug a RJ-14 connector into Base Unit
telephone line jacks mark L1 or L3.
c. The telephone cords supplied work for either type of
interface.
5. Installing the Base Unit AC Adaptor
a. Plug the transformer end of the Base Unit AC/DC adaptor
(7.5V) into a standard AC electrical power outlet, plug the
other end into the “DC In” jack on the back of the Base
Unit
b. To ensure uninterrupted services, the Base Unit’s AC/DC
Adaptor is best plugged into a UPS (Uninterruptible Power
Supply).
c. The base adaptor’s DC plug is larger in dimension than
the wireless handset charger’s DC plug. The charger
adaptor’s DC plug will not fit into the base’s DC-In jack.
6. Installing the Handset Battery
a. Insert the handset battery into the handset battery
compartment
b. Charge the handset battery pack for 4 hours until the
handset battery strength indicator on the handset LCD
display is full before the first usage.
7. Installing the Handset Charger AC Adaptor
a. Plug the transformer end of the Charger AC/DC Adaptor
(5.5V) into a standard AC electric power outlet, plug the
other end into the “DC In” jack on the back of the Charger.
b. The Handset Charger adaptor’s DC plug is smaller in
dimension than the Base Unit adaptor’s DC plug. The
charger adaptor’s DC plug will not fit into the base’s DC-In
jack
c. During an AC power outage, the charger will not be
charging the handset battery. To ensure uninterrupted
services, the charger’s AC/DC Adaptor is best plugged
into a UPS (Uninterruptible Power Supply).
Important Notes:
a. Recommended phone line features from the local phone
company:
i) Caller ID (Type I): allowing the display of incoming
caller information
22
ii) Hunt Group: Multiple phone lines “hunt group” is a
useful feature and works well with this phone system.
This feature “ties” multiple phone lines to a single
phone number. When an outside caller calls this
common phone number, the phone company
automatically finds a free line. In a hunt group, the
Call Waiting and the Caller ID with Call Waiting (or
called Type II Caller ID) features are unnecessary
because a 2nd call will come in on a separate line,
rather than on the same line. For a 2nd call coming in
on a separate line, the phone system’s built-in Second
Incoming Call feature will alert the user and allow the
user to toggle between multiple lines
b. The handset packaged along with a Base Unit is pre-
registered at the factory. If you have a new handset, you
will need to register the handset with the Base Unit in
order to be recognized as a member handset by the base
and by other handsets. See Handset Registration.
c. If the RCA 25450 is connected behind a PBX which does
not support the Caller ID feature, your RCA system won’t
be able to receive caller information and thus cannot
display and record the information.

23
