Telemetry Precautions
For proper management of the telemetry installation, consult your Fukuda
Denshi representative concerning the following:
' Plan the installation of your telemetry system taking into account your
entire medical facility needs and plant requirements.
' Be sure the antenna system installed meets the facility and plant
requirements.
This Radio Frequency device is susceptible interference from
Television station and other outside sources. Interference may
prevent the monitoring of patients connected to this devices. If
problems exist contact your local service representative.
NOTE : This device operates in the 400MHz UHF band. The exact
frequency of operation depends on designation, has been
present for your facility and may be identified by cross-
referencing the channel designator on the device with the
Telemetry Channel-Frequency Table in this manual.
To assure safe and reliable operation, observe the following precautions:
‘ Be sure that no other devices are using the frequency assigned to this
transmitten
' This device is susceptible to interference from electrosurgical knives
and other computerized equipment. If problems occur contact your
local Fukuda Denshi service representative.
' Any obstruction such as reinforced concrete or large metallic surfaces
between the receiver and the transmitter can affect reception. If
problems occur contact your local Fukuda Denshi service represen-

Users are advised to periodically contact the FCC and local TV
station to determine television transmission and other transmitter
a n...» ma.“ kn “can“ in chair nnnurnnhir nrna
Some paceimker pulss are difficult or not posible to demet
This "5 dependent on the amplitude and width of the pacemaker pulse in
addition to the type of pacemaker and lead type used (unipolar, bipolar, etc.)
QRS detection allows for detection of low amplitude ECG. But if
excessive artifact is present on the ECG waveform. the noise may be
detected as QRS in error.
Make sure each receiving telemetry channel corresponds to that of
the transmitter worn by the patient or by the transmission module
connected to a bedside monitor.
Instruct the patient wearing a telemetry transmitter to remain within
the range of the antenna system.
To avoid interference from other transmitters in the adjacent area or
hospital, make sure the proper channel identification and group
codes are used.
Refer system settings to your F ukuda Denshi service representative..

1. GENERAL DESCRIPTION
The LX—SlZO is a radio telemetry transmitter designed for monitoring the
ECG and Respiration. The transmitter will operate 5 continuous days
from one ”AA" size alkaline battery. On the top panel. Battery &
Electrodes status displays are provided.
The LX-SIZO is transmitting a digitized code that includes the trans-
mitting channel number and group codes to prevent the interference by
other radio apparatus. Read the receiver and display units operation
manual before using this transmitter.

(2) Poor Electrode Display
This lamp will light for two minutes when the electrodes are making poor
contact or the patient cables are broken or disconnected.
® Battery/Event Display
When the power switch is turned on, the battery check lamp will light for
about 10 seconds. If the battery is low, the lamp will not light after
turning on the power switch. The battery should be replaced with a new
one.
Also, when the Event switch is pressed, this lamp will light.
@ Hole for Security Strap.
Attach the accessory security strap to prevent dropping of the transmitter.

®Event switch
When this switch is pressed, this function will be activated at the
receiver. This can be designated on or off at the receiver,
© Channel number label
The transmitter channel number is printed on this label. Select the
receiver channel to correspond to this channel number.
® Battery cap
This is the battery compartment cap, To close the battery compartment,
align the mark on the cap and arrow mark on the lower pan of the
transmitter, then push and turn the cap clockwise to align the dot—marks
with each other.
(3) Electrode position label
Typical electrode positions are shown on this label.
® Power switch
This is the power switch. When the switch is turned to the ON position,
the ”Batt" lamp will be lit for about 10 seconds.
If the battery is weak or has no power, the "Batt" lamp will not light even
when the switch is turned to the ON position.
4. SET THE GROUP CODE
The LX-5I20 transmits a digitized code which includes the transmitting
channel number and group code to prevent interference from other radio
apparatus or a neighboring hospital's transmitter.
There are 64 group codes. Zero ("0") is set for factory adjustment.
The receiver is required to set the group code to match the transmitters
group code (The receiver group code's factory adjustment is ”0”).
The receiver is continuously checking the incoming channel number and
group code versus the number and code programmed to the receiver. if
the transmitter's group code is required to be changed, please contact your
nearest Fukuda representative,
{ NOTE : The system function to prevent interference will not work!

5. SELECT THE CORRESPONDING
RECEIVER CHANNEL
Select the receiver channel at the patient monitor to correspond to the
telemetry transmitters The channel number will be displayed on the
screen display If the receiver channel and transmitter channel do not
match, the monitor will display a caution and the unique waveform
shown below. This function will prevent telemetry channel interference
from other transmitters or external sources.
NOTE: This function will only be active if this has been incor-
porated into the receiver.
Example of DS-SSOON te emetry patient's display when interference is

This unique waveform Will also be displayed When a group or cnannei
number mismatch occurs.
