Blood Pressure Cautions
These cautions pertain to the Spot LXi blood pressure feature.
Caution Minimize extremity and cuff motion during blood pressure readings.
Caution If the blood pressure cuff is not at heart level, note the difference in
reading due to the hydrostatic effect. Add the value of 1.80 mmHg (.2 kPa) to the
displayed reading for every inch (2.5 cm) above heart level. Subtract the value of
1.80 mmHg (.2 kPa) from the displayed reading for every inch (2.5 cm) below
heart level.
Caution Proper blood pressure cuff size and placement is essential to the
accuracy of the blood pressure determination. See Reusable Two-Piece Cuff
Measurements or Durable One-Piece Cuff Measurements of the Directions for
Use for sizing information.
Caution The position and physiologic condition of the subject can affect a blood
pressure reading.
Temperature Cautions
These cautions pertain to the Spot LXi temperature feature.
Caution The SureTemp Plus feature only operates with the probe well in place.
Caution Do not use alkaline batteries in the Braun ThermoScan PRO 4000.
Caution Biting the probe tip may result in damage to the probe.
SpO2 Cautions
These cautions pertain to the Spot LXi SpO2 feature.
Caution The pulse oximeter is calibrated to determine the percentage of
arterial oxygen saturation of functional hemoglobin. Significant levels of
dysfunctional hemoglobin such as carboxyhemoglobin or methemoglobin may
affect the accuracy of the measurement.
Caution Some sensors may not be appropriate for a particular patient. If at
least 10 seconds of perfusion pulses cannot be observed for a given sensor,
change sensor location or sensor type for perfusion to resume.
Caution Physiological conditions, medical procedures, or external agents that
may interfere with the pulse oximeter’s ability to detect and display
measurements include dysfunctional hemoglobin, arterial dyes, low perfusion,
dark pigment, and externally applied coloring agents such as nail polish, dye, or
pigmented cream.
Caution When selecting a sensor, consider the patient’s weight and activity
level, the adequacy of perfusion, the available sensor sites, the need for sterility,
and the anticipated duration of monitoring.

Electronic components and assemblies, if not properly protected against ESD, can be
permanently damaged or destroyed when near or in contact with electrostatically charged
objects. When you handle components or assemblies that are not in protective bags and
you are not sure whether they are static-sensitive, assum that they are static-sensitive
and handle them accordingly.
•
Perform all service procedures in a static-protected environment. Always use
techniques and equipment designed to protect personnel and equipment from
electrostatic discharge.
•
Remove static-sensitive components and assemblies from their static-shielding bags
only at static-safe workstations - a properly grounded table and grounded floor mat and only when you are wearing a grounded wrist strap (with a resistor of at least 1
megohm in series) or other grounding device.
•
Use only grounded tools when inserting, adjusting, or removing static-sensitive
components and assemblies.
•
Remove or insert static-sensitive components and assemblies only with monitor
power turned off.
•
Insert and seal static-sensitive components and assemblies into their original staticshielding bags before removing them from static-protected areas.
Always test your ground strap, bench mat, conductive work surface, and ground cord
before removing components and assemblies fromtheir protective bags and before
beginning any disassembly or assembly procedures.

Functional Testing Procedures
Perform the functional testing procedures in this section before returning Spot LXi into
service.
Verify you are using a calibrated pressure meter with an accuracy of better than ±3 mmHg
and that the calibration certificate is traceable to NIST.
Subtract the rated accuracy of the pressure measurement standard from the ±3 mmHg
rated accuracy of Spot LXi. This is the pass/fail criteria to determine if the device is within
calibration. If the differences between Spot LXi and the pressure measurement standard
are within the pass/fail criteria at all specified pressures then the device is within
calibration.

Technical Overview
System Description
The Spot Vital Signs LXi automatically measures systolic and diastolic pressure (excluding
neonates), pulse rate, temperature (oral, adult axillary, pediatric axillary, rectal, and ear),
and pulse oximetry (SpO2) as well as calculates Mean Arterial Pressure (MAP).
Furthermore, Spot Vital Signs LXi allows the entry of height, weight, respiration rate, and
pain level. Spot Vital Signs LXi also calculates Body Mass Index (BMI) following height and
weight entry.
The device is intended to be used by clinicians and medically qualified personnel. It is
available for sale only upon the order of a physician or licensed health care provider.
Refer to the Spot Vital Signs LXi Directions for Use manual for complete information.
Battery System
Spot LXi includes a 6 Volt, 6 amp-hour sealed lead-acid battery that supplies all power to
the device. An external power supply charges the battery. The battery is always on-line
(floated) rather than switching out when attached to the external power supply.
Spot LXi uses a fuse and a shunt diode for protection against reverse battery connections.
The fuse is located on the main board in the negative battery line and a reverse battery
connection causes it to blow and require repair. The negative line location is more likely to
short the battery (+) wire to ground than short the battery (-) wire to the VBUS node.
Battery Charger
Provides two levels of power to fast-charge or to float the battery at fixed voltages using
software control. The fast-charge level rapidly brings the battery up to near-full capacity (7
Volts) using software to not overcharge the battery. The float level, set per the
manufacturer’s recommendation, slowly tops-off the battery and can stay on indefinitely.
“CPU I/O” Power Supply
Provides power to the I/O pins of the DragonBall MPU and the attached peripheral IC’s.
The nominal voltage is set to a value of 3.15 Volts so that both the 3.0 Volt MPU and 3.3
Volts peripherals can operate within specifications. Spot LXi uses buck switching topology
for efficiency and an on-off power latch directly controls the power supply.
CPU Core Power Supply
Powers the MPU core only and operates at the recommended Dragonball voltage range
of 1.8 +/- 0.1 Volts; 2.0 Volts absolute max.
60
Technical Overview
Welch Allyn Spot Vital Signs LXi
The +3.15 Volt supply powers the +1.8 Volt supply for efficiency and, more importantly, for
power sequencing. During power-on the +1.8 Volt supply cannot exceed the +3.15 Volt
supply. The R207/C182 further delays the +1.8 Volt supply. During power-off, D106
prevents the +1.8 Volt supply from exceeding the +3.15 Volt supply by more than a partial
diode drop.
+5V Supply
Provides supply to miscellaneous loads that require more than 3.15 Volts. The Power
Latch controls the supply and the average load current is small, so efficiency is not
important.
Clock/Calendar Power
The Clock/Calendar U19 receives power from two sources. During power on the clock
runs from the +5 Volt supply and during power down the clock receives power directly
from the battery potential using a voltage divider. Capacitor C131 provides power to the
U19 during the battery exchanges. Zener D102 prevents overvoltage to U19 in the case of
operation directly from the charger.
Mod F NIBP Power
This module is powered directly from VBUS through an EMI filter. Software via BP-PWRON-BAR controls the power. Level shifter Q115 / Q104 assures that the module remains
off when the MPU is unpowered.
SpO2 and Thermometer Power
A common structure supplies SpO2 and thermometry. A single push-pull driver delivers
squarewave power to a pair of isolation transformers, one for SpO2 and the other for
thermometry. THERM-PWR-BAR activates the driver under software control. Level
shifter Q118, Q119 assures that the module remains off when the MPU is unpowered.
In the push-pull (forward) configuration, VBUS is multiplied by the transformer turns ratio
and supplied to the input of the rectifier diodes. This is filtered and passed through lownoise 5-Volt linear regulators to supply power to the parameter modules.
LCD Power
The LCD data interface connects directly to the +3.15 Volt MPU I/O power supply. This
powers the driver ICs inside the LCD pane and assures the data interface to the LCD is
always powered when the unit is powered.
The contrast (bias) supply to the LCD panel and the LCD CCFL backlight both derive
power indirectly from a pre-regulator. A software control can shut down the pre-regulator.
For efficiency, it is implemented as a buck switcher operating directly from the battery.
The primary purpose of the pre-regulator is to protect the backlight inverter / ballast from
battery voltages that it cannot tolerate and to control current out of the unregulated
ballast. The voltage is set to the low side of 5 Volts to reduce battery consumption, while
still driving the CCFL with adequate voltage.
Service Manual
Technical Overview
61
External Load (RS-232) Power
There are two power outlet means on the Spot LXi – RS-232 port power and the Braun
PRO 4000 charger.
Two isolated power supplies provide power to each of the external RS-232 ports. This
power is available to external devices on pin 9 of each serial connector whenever the
software enables the corresponding RS-232 port.
SureTemp Plus Thermometer Interface
The SureTemp Plus OEM module is located in an optional pod and is connected to the
main PCB via a flex cable.The Thermometer Probe connection is located on a separate PC
board. It is connected to the SureTemp Plus OEM module by a ribbon cable. The
electrical interface to the thermometer pod is a 6-pin ribbon connector, Molex 52271-0690
or equivalent.
Braun ThermoScan PRO 4000 Thermometer Interface
The interface to the Braun ThermoScan PRO 4000 thermometer is located in the optional
pod and connects to the main PCB via a flex cable. The communications link is a single
duplex current loop that also charges the Braun battery pack.
The presence or absence of current passing through the Braun ThermoScan PRO 4000
charge contacts controls the interface charge LED, located within the pod, which mimics
the Braun ThermoScan Pro 4000 Base Station (type 6021).
SpO2 Description
A shielded flat-flex cable connects the user interface sensor connector J8 to the SpO2
electronics.
The Masimo SpO2 module mates to the Masimo Adaptor Board that, in turn, mates to the
Main board. This provides power and communications to the module from the Main
board.
The Nellcor SpO2 module mounts directly to the Main board. This provides power and
communications to the module, and brings the sensor signals to the main board where
EMI and ESD can be controlled. The sensor signals pass through the main board to the
mating connector for the shielded flat-flex cable.

Printer Description
All models of the Ap1300 printer use an industry standard RS-232 interface. The default
parameters are 9600 baud, 8 data bits, 1 stop bit, and no parity.
Serial data is expected in standard RS-232C format with -12 Volt meaning ‘mark’ or ‘1’ and
+12 Volt a logical ‘0’, with reference to the common ground. The serial data output line,
TxD, transmits XON/XOFF and status information to the host at the same Baud rate and in
the same format as the serial data input. The hardware busy line is true (nominal -12 Volt)
when busy. Both serial output lines will relax to approximately 0 Volt when the Ap1300 is
in sleep mode and the user must allow a short period after awakening before relying on
the values of these signals.
The Ap1300 has three operating modes, when not actually printing.
Idle Mode
Ready to accept data, but no data are in the buffer
awaiting printing and the printer motor is not running.
Sleep Mode
Effectively switched off.
Spool Mode
Active, but storing data for later printing.
Different color combinations on the front-panel LED indicate the modes. No light is
emitted in sleep mode.

* Spool may have resulted from Paper Out or Head Up conditions)
No hardware power switch is fitted, as power control is either automatic or by command
from the host computer. To save power, the printer enters sleep mode after a period of
inactivity, factory-set to 30 seconds, but prorammable from the host. It can also be
programmed to stay idle indefinitely or to go to sleep on command.
The Ap1300 utilizes Fujitsu FTP-628MCL 103 printer mechanism, with a fixed (parallel)
print head with 384 horizontally-arranged thermal elements. A stepper motor advances
the paper and the printing takes place in a single-dot row for each step of the paper. Each
printed dot is approximately 1/8 mm square. The printing speed and dot density are
controlled according to the battery voltage and the head temperature.

Technical Overview
Welch Allyn Spot Vital Signs LXi
The Spot LXi provides two levels of power to fast-charge or to float the battery at fixed
voltages using software control. The fast-charge level rapidly brings the battery up to
near-full capacity (7 Volts) using software to not overcharge the battery. The float level, set
per the manufacturer’s recommendation, slowly tops-off the battery and can stay on
indefinitely.
