For transmitters rated at a maximum output power not listed above, the recommended separation distance d

in metres (m) can be estimated 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.

NOTE 1 At 80 MHz and 800 MHz, the separation distance for 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.

• Guidance and manufacturer’s declaration – electromagnetic immunity

The device is intended for use in the electromagnetic environments listed below, and should only be

used in such environments:

Portable and mobile RF communications equipment should be

used no closer to any part of the device, including cables, than

the recommended separation distance calculated from the equa-

tion 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 and d is the

recommended separation distance in metres (m).

Field strengths from ﬁxed RF transmitters, as determined by an

electromagnetic site survey, a should be less than the compli-

ance level in each frequency range.

b 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 device is used exceeds the applicable RF compliance level above, the device should be observed to

verify normal operation. If abnormal performance is observed, additional measures may be necessary,

such as reorienting or relocating the device.

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

TROUBLESHOOTING

If any abnormality arises during use, please check the following points.

Note: If the unit still does not work, contact HoMedics

Consumer Relations.

Under no circumstance should you disassemble or attempt to repair the

unit by yourself. Contact information for HoMedics

Consumer Relations

Department can be found on the warranty page.

SYMPTOMS

POSSIBLE

CAUSES

CORRECTION

Unit does not turn

on when the START/

STOP

button is pushed.

Batteries have

run down.

Replace them with

four new AA

alkaline batteries.

Battery polarities

have been positioned

incorrectly.

Re-insert the batteries

in the correct positions.

EE measurement error

symbol shown on dis-

play or the blood pres-

sure value is displayed

excessively low

(or high).

Cuff has been placed

incorrectly.

Wrap the cuff properly

so that it is positioned

correctly.

Did you talk or move

during measurement?

Measure again. Keep

arm steady during

measurement.

Shaking of the arm with

the cuff on.

E1 error symbol shown

on display

Air circuit abnormality.

Cuff tube may not be

plugged into monitor

correctly.

Check cuff connection.

Measure again.

E2 error symbol shown

on display

Inflation pressure

exceeding 300 mmHg.

Switch the unit off, then

measure again.

E3 error symbol shown

on display

Error determining

measurement data.

Measure again.
