If the unit is used for over 10,000 times,
the calibration reminding message (CAL)
will appear every time the unit is switched
on. It is recommended that calibration be
completed every two years. Only the man-
ufacturer or an authorized service techni-
cian is qualified for the calibration service.
Please contact the manufacturer, Rossmax
International Ltd. or your local distributors. (The PC Link socket
for calibration purpose is inside the battery compartment.)

The default is to have the back light on once the pressure is in-
flated over 30 mmHg, and throughout the measurement pro-
cess. To switch the back light off at any time, press the “ ”
key.
1. Rossmax Mandaus II are exclusively designed for blood pres-
sure measurement at the upper arm or thigh on healthy skin.
2. Please do not inflate to more than 300 mmHg.
3. Do not take your blood pressure for more than 3 minutes.
4. Wait for at least 2 minutes before repeated measurements.
12. Safety Information
1. The unit contains high-precision assemblies. Therefore, avoid ex-
treme temperatures, humidity, and direct sunlight. Avoid drop-
ping or strongly shocking the main unit, and protect it from
dust.
2. Clean the blood pressure monitor body and the cuff carefully
with a slightly damp, soft cloth. Do not press. Do not wash the
cuff or use chemical cleaner on it. Never use thinner, alcohol or
petrol (gasoline) as cleaner.

The Mandaus II uses RF energy only for its internal function. Therefore, its RF emissions
are very low and are not likely to cause any interference in nearby electronic equipment.

Portable and mobile RF communications equipment should be used
no closer to any part of the Mandaus II, including cables, than the
recommended separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance:
d = 1,2 √P
d = 1,2 √P 80MHz to 800 MHz
d = 2,3 √P 800MHz to 2,5 GHz Where P is the maximum output power
rating of the transmitter in watts (W) according to the transmitter manu-
facturer and d is the recommended separation distance in metres (m).
Field strengths from fixed RF transmitters, as determined by an electro-
magnetic site survey, a should be less than the compliance level in each
frequency range.b
Interference may occur in the vicinity of equipment marked with the fol-
lowing symbol:
NOTE1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE2: 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, ama-
teur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromag-
netic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in
the location in which the Mandaus II is used exceeds the applicable RF compliance level above, the Mandaus II should be observed
to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or
relocating the Mandaus II.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distance between
portable and mobile RF communications equipment and the Mandaus II
The Mandaus II is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer
or the user of the Mandaus II can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the Mandaus II as recommended below, according to the maximum output
power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be es-
timated using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter
in watts (W) according to the transmitter manufacturer.
NOTE1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
