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 risk of 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. Remember: 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
device 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

5
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
carry the handset in a breast pocket. If you have
any reason to suspect that interference is taking
place, turn off your handset immediately.
Product Safety Instructions
1. Read and understand all instructions.
2. Follow all warnings and instructions including those

Regulatory Information
SR-436
FCC ID: NNA-SR-436
Canada ???????????
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 and Canadian IC/DOC CS-03. On the
bottom of the base station 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. or CA-11A in Canada. 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

10
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.
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 and RSS210
of the DOC 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/tonearby TV’s, VCR’s, radios,
computers, or other electronic devices. To
minimize or prevent such interference, the
telephone system should not be placed or operated
near other electronic devices. If interference
occurs, moving the base station 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 bedetermined 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 station and the device that is

11
experiencing interference. We recommend at
least 20 feet between the system and other
electronic devices.
b. Connect the base station 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.

Wireless Local Loop applications. The SR-436 is the
longest range, multi-line telephone and 2-way radio
communications system providing users unparallel
mobility and flexibility.
With sophisticated digital signal processing and high
quality hardware designs, the SR-436 provides long-
range telephone connections and 2-way handset-to-
handset communications in the “last-mile” connection
as well as a wide variety of business settings from
multi-level office buildings, factories, hotels/resorts,
convention facilities, warehouses, farms, business
complexes, construction sites, and other demanding
business environments.
The unique 2-way radio feature allows handsets to
