Products; Medical Products Act; European Standards for Electrical Medical Equipment EN60601-1
(General Safety Provisions), EN60601-2-30 (Particular Requirements for the Safety of Automatic
Cycling Indirect Blood Pressure Monitoring Equipment), EN60601-1-2 and EN55011 (Electromagnetic
Compatibility); European Standards pertaining to Non Invasive Blood Pressure Instruments EN1060-1
(General Requirements), EN1060-3 (Supplementary Requirements for Electromechanical Blood Pressure
Measuring Systems). The above is evidenced by the CE mark of conformity accompanied by the
reference number of a designated authority. This device is designed for adults only.
Compliance with FCC Rules
Please note that this equipment generates, uses and can radiate radio frequency energy. This
equipment has been tested and has been found to comply with the limits of a Class A computing

SYS Systolic Blood Pressure
DIA Diastolic Blood Pressure
DSD The Difference between Systolic Blood Pressure and Diastolic
Blood Pressure.
Exhaust This means "releasing the cuff air as soon as possible".
Constant exhaust This means "releasing the cuff air in a constant depressurization rate".
Exhaust velocity This means the rate of depressurizing the cuff air.
During a measurement This means "a period between the start of cuff inflation and the
end of exhausting the air".
Interval This is called "block". A block consists of a start time and frequency.
bpm beats per minute.

Precautions for Use
Precautions
Batteries
Use alkaline batteries (LR6 type, AA type, Mignon) or suitable Ni-Cd batteries.
Do not mix new and used batteries in the recorder.
Remove the batteries from the recorder, if it will not be used for a long period of
time and unless there is no risk of a SAFETY HAZARD arising.
A malfunctioning recorder
If the recorder malfunctions, stop the operation, attach a note "Do not use this
recorder" and store in a safe place to avoid mis-use.
Training
Instruct the patient on how to stop the operation if there is an abnormal
measurement, and how to remove the cuff if there is excessive arm pain.
Advise the patient on how to cope with mis-operation and contingencies
Repair
Do not open the recorder case. Contact the nearest A&D office if you have
questions.
Blood pressure measurement
Use the recorder for adult.
The recorder may not make a measurement when a patient has continuous
arrhythmia or the recorder senses noise due to the patients movement.
Please check measurement values by other methods, if you suspect an value.
Do not use this recorder on a person who is using a heartlung machine and a
defibrillator.
Do not use this recorder on a person who is critical or is in an intensive care unit.
Saving power
Turn off the power switch when not in use.
Please transfer the data as soon as possible. All measurement data, clock
parameters, measurement parameters and internal system parameters are
preserved by backup battery when turning the power switch off. The backup
battery life is few days.
Data in memory
A built-in backup battery keeps the important data in memory while replacing the main
batteries. However it works for a short period of time, perform the battery replacement
swiftly, or you may lose measurement data, the clock setting information and

Page 4
automatic measurement condition data. The period varies depending on the battery condition.
The backup battery may take 24 hours or more to be fully charged
(depending on the battery condition).
The built-in backup battery (rechargeable) as well as the primary battery (not
rechargeable) will deteriorate along use, which causes to decrease its capacity. The
built-in backup battery will deteriorate due to repetitive backup operations.
To prevent the sudden drop of the built-in battery life, observe the following:
Before using the monitor for the first time after purchase or after an extended period of
no use, charge the battery fully. It takes 24 hours or more with the power switch
turned on. Charging can be performed during measurement.
After measurement, leave the battery inside and the power switch turned on. Under
this condition, the built-in battery will not deteriorate. (This is true with the "B" sign
displayed.)
When the monitor is not to be used for a month or longer, turn the power switch off to
prevent the main batteries from leaking. During an extended period of no use, the
built-in battery will deteriorate. To prevent the situation, use the monitor regularly.
When the power switch is turned on and off after a short period of use, the built-in
battery will not be fully charged and the battery life will decrease. Avoid this situation.
Cuff
Close the cuff fastener properly when attaching the cuff to a patient or
replacing the cuff cloth. If the fastener is closed incorrectly, inflating cuff may
damage this cuff.
The cuff contains dry natural rubber.

Notes on the Blood Pressure Recorder
Storage
Do not store the recorder in the following places.
Where the recorder might be splashed with water or other liquids. If the
recorder soaked, it needs a repair. (Do not use the recorder.)
Where the temperature and humidity are high, or in direct sunlight.
Where the recorder may be influenced by vibration or shock.
Where there is dust, salt or sulfur.
Where medicines are stored, or medicines are evaporating.
Before use
Cover the RS-232C terminal using the rubber cap, to avoid dust.
Confirm that the recorder works correctly and measurement values are proper.
Confirm that the cuff and air house are connected properly.
Confirm parts of contact with patient directly. Keep clean for these parts.
Use clean cuff cover because of contact with patient directly.
Clear the old data before starting a new measurement.
Avoid strong magnetic field and static electricity.
Do not use this recorder with a high frequency surgical equipment.
During use
The recorder should be operated by a physician who knows it well.
Use the recorder only during the time of diagnosis or medical treatment.
Stop the use, if the patient feels pain in his arm or the recorder does not measure
properly.
It may reduced the measurement cycle due to environment.
When an inside part of the recorder has been soaked (wetted), turn off the power
switch and request service to your supplier or the A&D service group.
After use
Clean the recorder, cuff and accessories for the next use. Do not pull or kink hoses.
Do not use organic solvent, antiseptic solution, etc.
Turn off the power switch after measurement.
Please use the original box for transportation.
Periodic maintenance
The recorder is a precision instrument. Please check all functions (every year)
periodically. Contact your nearest A&D office for this inspection.
Environmental protection
If you disuse the recorder, remove Ni-Cd battery and built-in Li battery from this
recorder.
Disuse Ni-Cd battery to its exclusive trash can because of recycling it.
Dispose of Li coin battery in the recorder as dangerous object properly.

Welcome
Welcome and Intention
Thank you for your Purchase!
The A&D TM-2430 ambulatory blood pressure recorder enables you to
accurately take a patient's blood pressure, automatically, at different preset times
throughout a 24-hours period.
Recently, in the treatment of patients with hypertension, there has been an
increasing need to prescribe medication according to the particular blood
pressure fluctuation pattern of the patient. These patterns can be made more
evident by using the TM-2430 recorder, and analysis by a physician.
This manual will explain in simple language how this recorder works.
Patient
This blood pressure recorder is designed for an adult patient.
Environment
This blood pressure recorder is used in a hospital and / or patient’s home.
