Operation Instructions

The M-310 (MS-4400I) is designed to be

held whilst a baby is being weighed, as

shown in the picture on the left.

To begin, switch the scale on by pressing

the ON/OFF/ZERO button. 0.00kg should

show on the display.

Lay the sling out on a flat surface.

Gently place the baby in the sling.

Attach the S hook to the bottom of the

scale and to the hoops on the sling.

Holding the M-310 (MS-4400I) as shown

in 1), gently lift the baby off the flat

surface.

(Alternatively, if you need to remove the

weight of the sling or any other item from

the reading, hook the sling/item and sling

to the scale and press TARE. You can then

weigh the baby as normal.)

The weight reading will show clearly on the

display.

You can also press HOLD to stabilise the

weight reading on the display.

Press ON/OFF/ZERO to switch the scale off.

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, 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 scale is used exceeds the application RF compliance level above, the scale should be observed to

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

such as re-orienting or relocating the scale.

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 M-310 (MS-4400I).

This scale is intended for use in an electromagnetic environment in which radiated RF disturbances are

controlled. The customer or the user of the scale can help prevent electromagnetic interference by

maintaining a minimum distance between portable and mobile RF communications equipment (transmitters)

and the scale 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 estimated using the equation applicable to the frequency of the transmitter, where p is

the maximum output rating of the transmitter in watts (w) according to the transmitter manufacturer.

NOTE1) At 80 MHz and 800 MHz, the separation distance for the high 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.
