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.

160 Maintenance Welch Allyn Propaq LT Vital Signs Monitor
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.
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.
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 Maintenance 161
Inspecting and Cleaning the Monitor and Accessories
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.
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.
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.

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.

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.

• All medical electrical equipment must be installed and put into service in
accordance with the EMC information provided in this document.
• Portable and mobile RF communications equipment can affect the behavior of
medical electrical equipment.
Propaq LT Series monitors and accessories comply with all applicable and required
standards for electromagnetic interference.
• They do not normally affect nearby equipment and devices.
• They are not normally affected by nearby equipment and devices.
• It is safe to operate them in the presence of high-frequency surgical equipment;
however, it is good practice to avoid using the monitors near other equipment.

Field strengths from fixed RF transmitters, as determined by
an electromagnetic site surveya, should be less than the
compliance level in each frequency rangeb.
Interference may occur in the vicinity of equipment marked
with the following symbol:
Note 1 At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios,
amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the
electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured
field strength in the location in which the Propaq LT Series monitor with Charging/Communication Cradle and Large Color Display
Interface is used exceeds the applicable RF compliance level above, the Propaq LT Series monitor with Charging/Communication
Cradle and Large Color Display Interface should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the Propaq LT Series monitor with Charging/
Communication Cradle and Large Color Display Interface.

The Propaq LT Series monitor with Charging/Communication Cradle and Large Color Display Interface is intended for use
in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the
Propaq LT Series monitor with Charging/Communication Cradle and Large Color Display Interface can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the Propaq LT Series monitor with Charging/Communication Cradle and Large Color Display
Interface as recommended below, according to the maximum output power of the communications equipment.
