Rossmax AC701k Instruction Manual

The National High Blood Pressure Education Program Coordinating
Committee has developed a blood pressure standard, classifying blood
pressure ranges into 4 stages. (Ref. The Seventh Report of the Joint Na-

tional Committee on Prevention, Detection,
Evaluation, and Treatment of High Blood
Pressure-Complete Report JNC-7, 2004).

This blood pressure classification are based
on historical data, and may not be directly
applicable to any particular patient. It is
important that you consult with your physi­cian regularly. Your physician will tell you
your normal blood pressure range as well
as the point at which you will be considered
at risk. For reliable monitoring and refer­ence of blood pressure, keeping long- term
records is recommended. Please download
the blood pressure log at
www.rossmaxhealth.com.

Attention: Consult the accompanying documents. Please read this manual

carefully before use. For specic information on your own blood

pressure, contact your physician. Please be sure to keep this
manual.

Blood pressure measurements determined with AC701k are equivalent to
those obtained by a trained observer using cuff/stethoscope auscultation
method, within the limits prescribed by the American National Standard, Elec­tronic or Automated Sphygmomanometers. This unit is to be used by adult
consumers in a home environment. Do not use this device on infants or neo­nates. AC701k is protected against manufacturing defects by an established
International Warranty Program. For warranty information, you can contact
the manufacturer, Rossmax International Ltd.

- Part 4: Test Procedures to determine the overall system accuracy of auto-

mated non-invasive sphygmomanometers.
This blood pressure monitor was designed for long service time. To ensure
continued accuracy, it’s recommended that all digital blood pressure mon­itors require re-calibration. This monitor (under normal usage with approx.

3 measurements a day) does not require re-calibration for 2 years. Once

the unit should be re-calibrated the device will display

.
The unit should also be re-calibrated if the monitor sustains
damage due to blunt force (such as dropping) or exposure
to uids and / or extreme hot or cold temperature / humid­ity changes. When appears, simply return to your nearest
dealer for re-calibration service.

Here are a few helpful tips to help you obtain more accurate readings:

• Blood pressure changes with every heartbeat and is in constant fluctuation

throughout the day.

• Blood pressure recording can be affected by the position of the user, his or

her physiological condition and other factors. For greatest accuracy, wait
one hour after exercising, bathing, eating, drinking beverages with alcohol
or caffeine, or smoking to measure blood pressure.

• Before measurement, it’s suggested that you sit quietly for at least 5 minutes

as measurement taken during a relaxed state will have greater accuracy. You
should not be physically tired or exhausted while taking a measurement.

• Do not take measurements if you are under stress or tension.

• During measurement, do not talk or move your arm or hand muscles.

• Take your blood pressure at normal body temperature. If you are feeling cold

or hot, wait a while before taking a measurement.

• If the monitor is stored at very low temperature (near freezing), have it

placed at a warm location for at least one hour before using it.

• Wait 5 minutes before taking the next measurement.

1. Press the User-Switching key to select memory zone 1 or memory zone 2.
After a memory zone is selected, press the START/STOP key to reset the

monitor so it can start measurement in the chosen memory zone.

2. Press the START/STOP key. All digits will light up, checking the display func­tions. The checking procedure will be completed in 2 seconds.

3. After all symbols appear, the display will show a blinking “0”. The monitor
is ready to measure and will automatically inflate the cuff slowly to start
measurement.

4. When the measurement is completed, the cuff will exhaust the pressure
inside. Systolic pressure, diastolic pressure and pulse will be shown simulta­neously on the LCD screen. The measurement is then automatically stored

into the pre-designated memory zone.

This monitor will re-inflate automatically to approximately 220 mmHg if the

system detects that your body needs more pressure to measure your blood
pressure.
Note: 1. This monitor automatically switches off approximately 1 minute after

last key operation.

2. To interrupt the measurement, simply press the START/STOP or

Memory key; the cuff will deflate immediately.

3. During the measurement, do not talk or move your arm or hand

muscles.

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

reection from structures, objects and people.

a: Field strengths from xed 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 xed RF transmitters, an electromagnetic site survey should be
considered. If the measured eld strength in the location in which the AC701k is used exceeds the applicable RF com­pliance level above, the AC701k should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the AC701k.

b: Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 3 V/m.

Recommended separation distance between portable and mobile RF communications equipment and the AC701k
The AC701k is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the AC701k can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the AC701k as recommended below,
according to the maximum output power of the communications equipment.
