Recharging the Battery
The monitor battery is recharged whenever the monitor is placed into a cradle that is
connected to a suitable power source. Recharging occurs whether the monitor is on or
off. While in a cradle that is connected to AC power, the monitor also receives operating
power from the cradle, thus preserving battery power for use when the monitor is
removed.
To Recharge the Battery
1.
Confirm that the green
“power” light (the right of
two on the cradle) is on.
If it is off, plug the power
adapter into the cradle.
2. Insert the monitor into the
cradle until it clicks into
place.
3. Confirm that the green
“battery charging” light on
the cradle (the left of two on
the cradle) is on.
•
If the green “battery
charging” light is off, the
monitor battery is
already fully charged.
•
A steady yellow light
indicates a problem with
the battery or the cradle
(contact a qualified
service technician) or
that the monitor is not
properly seated in the
cradle.
Green: monitor is
running on cradle
power
Green: battery is

Yellow: battery or

Maintenance
Welch Allyn Propaq LT Vital Signs Monitor
Note
The yellow light might flash briefly when the monitor is being inserted in the
cradle or removed from the cradle. This is normal behavior and does not indicate a
problem.
4. When the battery is fully charged, the green “battery charging” light is off.
•
Keep the monitor in the cradle whenever the patient is in bed. This keeps the
monitor battery at full charge, so that it is ready for use if it must be removed
from the cradle.
•
You can leave the monitor in the cradle when the battery is fully charged.
WARNING Do not incinerate, submerge, crush, disassemble, or autoclave the
lithium-ion battery.
Caution Do not remove or replace the battery unless you are a Welch Allyn
qualified service technician.
Caution Do not use the monitor while the battery is being replaced.
Directions for Use

Inspecting and Cleaning the Monitor and Accessories
WARNING Do not autoclave the monitor, the cradle, the AC power adapter, or
any accessories.
WARNING Do not immerse the monitor, the cradle, or the AC power adapter in
liquid when cleaning. Do not immerse accessories in liquid when cleaning unless
the accessory manufacturer’s cleaning instructions explicitly instruct you to do so.
WARNING Fire and electrical shock hazard. Always unplug the AC power
adapter from the electrical power outlet before inspecting or cleaning the cradle,
the AC power adapter, or the monitor. Exposing any of these to liquids, such as
cleaning solutions, while they are connected to electrical power could result in
electrical shock or fire.
Before cleaning the monitor, cradle, AC power adapter, or any accessories, thoroughly
inspect them.
•
Look for any signs of damage and any improper mechanical function of buttons or
connectors.
•
Gently bend and flex cables, inspecting them for damage or extreme wear, exposed
wires, or bent connectors.
•
Confirm that all connectors engage securely.
Immediately report any sign of damage or malfunction to your service department.
At least once per year, thoroughly inspect the cradle and the AC adapter power cord for
damage or extreme wear.
To clean the monitor, the cradle, or any accessories, follow these steps:
1.
Wipe the equipment with a cloth slightly moistened (not wet) with one of the
approved cleaning solutions listed in Table 12 on page 162.
2. Thoroughly wipe off any excess cleaning solution. Do not let the cleaning solution run
into or accumulate in connector openings, latches, or crevices. If liquid gets into
connectors, dry the area with warm air, and then check the equipment to confirm that
it operates properly.
Caution Use only a cleaning solution recommended by Welch Allyn for this
equipment. Use of any other cleaning solutions which have a high acid content or
are otherwise inappropriate can cause damage to the equipment, including
cracking and deterioration of the plastic case.
Caution Always follow the mixing/diluting instructions provided by the
manufacturer of the cleaning solution.

The equipment can be disinfected to comply with OSHA requirements for cleaning and decontaminating spills of blood and other body
fluids. (Federal OSHA Standard on bloodborne pathogens: 29 CFR 1910.1030, 12/6/91.)
If liquid gets into the connectors, dry the area with warm air and then verify all monitoring functions.
Wex-cide (Wexford Labs, Inc., Kirkwood, MO) and T.B.Q. (Calgon Vestal Lab., Calgon Corp., St. Louis, MO) are disinfectants that meet
OSHA requirements, are EPA approved, and will not harm the outside of the monitor, battery, or battery charger. Wipe away
disinfectants with a water-dampened cloth after the manufacturer’s recommended period.
Recycling Monitor Components
Within the EU
Do not dispose of this product as ‘unsorted municipal waste’. Prepare it for reuse
or separate collection as specified by Directive 2002/96/EC of the European
Parliament and the Council of the European Union on Waste Electronic and
Electrical Equipment (WEEE).
Note
If the monitor, the cradle, or the battery is contaminated, this directive does not
apply.
For more specific disposal information, see www.welchallyn.com/weee, or contact Welch
Allyn Customer Service.
Outside the EU
When the monitor, the cradle, or the battery reaches end of life, recycle it locally
according to national, state, and local regulations, or return it to Welch Allyn.

HR averaging method
HR = 60/(latest average interval in seconds)
For higher HR, latest avg interval = 7/8 (previous avg interval) + 1/8 (latest interval).
For lower HR, latest avg interval = 3/4 (previous avg interval) + 1/4 (latest interval).
Transition rates for choice of formula include hysteresis and are 70 and 80 beats/min.

EC13-2002, 4.2.6.3)

Pacer pulse display indication
Pacer indicator (dashed vertical marker) shown on screen if pacer indicator is ON; pacer
signal always shown if of sufficient amplitude.
Pacer pulse detection (i.e., for
which the monitor displays a

Pulses = ± 3.2 mV to ± 700 mV @ 0.1 ms and ± 2 mV to ± 700 mV @ 0.2 to 2 ms, all with
or without overshoot, in electrically quiet environment. Thresholds automatically adjust
to reject repetitive ambient noise. Pacer detector influences QRS picking even while
pacer display indication is disabled.

Does not count as heartbeats approximately 95% of pacemaker pulses within pacer
pulse detection range, with or without AAMI (EC 13-2002) tails of 4, 8, 15, 25, 50, 75, or
100 ms decay time constant, whose tail amplitudes meet either EC 13’s method A or

Probe accuracy for saturation levels below 70% is unspecified.
When sensors are used on neonatal subjects as recommended, the specified accuracy range is increased by ± 1 digit as compared to
adult usage, to account for the theoretical effect on oximeter measurements of fetal hemoglobin in neonatal blood. For example,
MAX-N accuracy on neonates is ± 3 digits, rather than ± 2 digits for adults.

To keep false alarms to a minimum, the monitor briefly delays or “holds off”
triggering audible and visual alarms for limit violations for these vital signs.
After the hold-off period begins, if the monitor detects that the vital sign has
returned to acceptable limits, the monitor cancels the alarm. The next time a
limit is violated, the monitor starts a new hold-off.
Audio alarm hold-off with Acuity
When a monitor is connected to Acuity, the audio alarms at the monitor can
be delayed up to 4 minutes and 15 seconds. The delay time is selected in
Acuity software at the time of Acuity installation. Visual alarm indications
are not delayed.
Acuity has a default audio alarm hold-off of 11 seconds.
Alarms suspend
When ‘alarms suspend’ is enabled, the monitor alarm tones for all
parameters can be suspended on the floor for a configurable period: 90
seconds, 2 minutes, 3 minutes, 4 minutes (default), 5 minutes, 10 minutes, 15
minutes, or 60 minutes.
Patient out-of-range;
transmitter failure
When a monitor is used with Acuity, an equipment alert is generated
whenever the monitor fails to communicate with Acuity after a connection
has been successfully established. In addition, the ‘No Acuity’ icon is
displayed on the monitor.
Battery failure
An equipment alert is generated before the monitor battery becomes
exhausted.
Snapshot/event mark
When
is pressed, the monitor records a Snapshot. If the monitor is
connected to Acuity, the monitor also sends a message to Acuity so Acuity
can mark and print it.
