0 When using the instrument in conjunction With another instrument,
follow the appropriate instructions for both instruments.
Caution during Operation
Observe the instrument and patient for any abnormality. If abnormal
operation occurs, remove the instrument from use and have it checked
by the biomedical engineering department or contact your nearest
Fukuda Denshj service representative.
Cautions after Operation
0 Turn off the power switch when operation is complete.
. Disconnect cables properly by holding the plug and pulling it out
gently.
- Clean the instrument prior to storing.
Non-explosion-proof
The instrument is not designed for operation in areas in which there
is a risk of explosion,
Be sure to perform a periodical inspection of the instrument and all
accessories.
CLEANING AND DISINFECTION
Electrodes and electrode cables
For disinfection, the electrodes and electrode cables should be
rubbed with a swab or cloth moistened with a formaldehyde
solution, such as Cidex 5%.
Under no circumstances may the electrode cables be immersed in
any cleaning fluid, nor may they be subjected to heat sterilization
with water, steam, or air, or be subjected to ether sterilization.
Transmitter
The transmitter cabinet may be cleaned and disinfected in the
following manner.
Cleaning:
Rub the unit with a cleaning cloth moistened with water to which an
ordinary household cleaning agent can be added if necessary. But
never use ether or benzene.
Disinfection:
Thoroughly spray the cabinet with a 5% Cidex or a similar product.
Any and all modifications must be performed by an authorized
Fukuda Denshi service representative.
iii
iv
Some pacemaker pulses are difficult or not possible to detect.
This is 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 receivmg telemetry channel corresponds to
that of the transmitter worn by the patient.
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 Fukuda Denshi service
representative.

1. GENERAL DESCRIPTION
The LX—5160 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
and electrodes status displays are provided.
The LX-5160 is transmitting a digitized code that includes the
transmitting channel number and group codes to prevent interference
by other radio apparatus. Read the receiver and display unit
operation manual before using this transmitter.
Operation of this equipment requires the prior coordination
With a frequency coordinator designated by the FCC for the
Wireless Medical Telemetry Service.

®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 the transmitter from
dropping. Adjust the length of the strap to the appropriate length for
the patient.
©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
part of the transmitter, then push and turn the cap clockwise to align
the dot-marks with each other.
‘Electrode Position Label
Typical electrode positions are shown on this label.
®P0wer 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.
3. PREPARATION & OPERATION
Loading a battery
The LX-5160 uses one "AA" size alkaline cell (LR-6) for its power
source.
When installing a battery taking note of the polarity. To close the
battery compartment, align the mark (yellow) on the cap and the mark
(yellow) on the lower part of the transmitter, then gently push in and
turn the cap clockwise to the mark (white) on the transmitter to align
the dot—marks (white & yellow) with each other.
If the transmitter is not in use for a long period of time, remove the
battery and store in an appropriate place.
Turn the power switch to "ON"
Turn the power switch, which is located at the bottom of the
transmitter, on the battery cap, to the "ON" position.
The battery life will be approximately 5 days of continuous operation.
Do not use in high humidity or in areas of high oxygen
concentration.
Attaching the electrodes
Wipe the skin at the electrode site with alcohol. Then detach the
electrode from the electrode mount and attach it to the electrode site.
Color coding of the electrode positions are shown below.
Adhesive tape should be used to tape the electrode wire to the skin to
prevent the lead wire from moving on the electrode.
With the LX-5160 impedance measurements are used for respiration
monitoring. There is a possibility that a large amplitude ECG signal
will not always provide a large respiration signal. In general, lead
CC5, as illustrated below, will provide the best respiration waveform.
EXAMPLE OF ELECTRODE POSITIONS
For single lead ECG and respiration monitoring, use the CM-85B for
AHA color code or CM-86B for IEC color code patient cable (three
electrodes). AHA color code is applied in USA. and IEC color
code is applied in Europe,

Connect the lead wire set firmly to the transmitter.
Connect the patient cable firmly to
the ECGfllesp. input connector of
the transmitter.
When disconnecting the patient
cable, do not disconnect the lead
wire set by pulling on the wires.
Confirm the direction of the keyed plug to match the
transmitter's guide key on the connector. Improper
connection will cause damage to the transmitter, patient cable,
and will not provide proper monitoring.

4. SET THE GROUP CODE
The LX—5160 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
transmitter's 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 Fukuda Denshi.
NOTE: The system function to prevent interference will not ,
’ work if the receiver does not incorporate this function. "
5. SELECT THE CORRESPONDING
RECEIVER CHANNEL
Select the receiver channel at the patient monitor to correspond to the
telemetry transmitter. 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
incorporated into the receiver.
Example of the DS-5800N telemetry patient‘s display when
interference is present.
WU'LLURLF
This unique waveform will also be displayed when a group or channel
number mismatch occurs.

6. CLEANING AND DISINFECTION
Clean the transmitter and patient cable with gauze or sanitary cotton
dampened with alcohol or inert soap. Be sure not to get cleaning
liquid into the patient lead connector and battery compartment.
Do not use cleaner containing organic solution, thinners, toluene,
benzene. Do not autoclave or heat the unit and patient cable above
60°C.
When the room is disinfected by spraying, take proper measures so the
chemical solution does not get on the connector or enter into the inside
of the enclosure
