Intended Use

• This scale is intended for use to determine the weight of patients, supported by professional personnel and in rooms intended for carrying out healthcare.
• The weighing value can be read after a stable weighing value has been obtained. Before use, the scale must be checked by an authorised person to ensure it’s in a suitable condition.
• The device is intended to measure one subject at a time.

Explanation of Graphic Symbols

Power Supply and Low Battery

The indicator uses a rechargeable battery pack, or a non-rechargeable battery pack, or can be powered from the mains via the AC adaptor. Make sure the battery pack is installed in the battery box of the indicator. Alternatively, plug the AC adaptor (12V 2A) into the port on the side of the indicator.

Installing and Replacing the Battery Pack

1. Take out the battery housing.
2. The rechargeable battery pack will slide into, or out of, the housing.
3. Check that the housing pin is connecting to the right point inside the indicator.
4. Place the housing back in the back of the indicator and close the battery housing cover.

Setting the Date

Press HOLD for three seconds to access the time setting mode. The period digit that is flashing can be changed by using the numeric keys. The period to be edited is selected by pressing HOLD. E.g., To input 25 December 2008, 8:00 a.m.

Using the Scale with a Printer
An optional Marsden external printer (model TP-2100) is available for all models. With the printer fitted, the patient’s weight, height, and BMI results can be printed. Once the person has been weighed and their BMI calculated, simply press PRINT to produce the following ticket.

Connecting the TP-2100 Thermal Printer

Plug the cable into the printer, and then connect its 9D connector to the indicator.

Using the Scale with Wi-Fi/Bluetooth
If your scale has device connectivity, the universal wireless symbol will be on the main indicator display. If your scale does have Wi-Fi or Bluetooth connectivity, we do not supply the software to capture the data from the weighing scale. We do however provide the protocols for you to implement the devices into your software.

EMC Guidance and Manufacturer’s Declaration
Guidance and manufacturer’s declaration – electromagnet emissions. The M-800 is intended for use in the electromagnetic environment specified below. The customer or user of this scale should ensure that it is used in such an environment.

Emission Test| Compliance| Electromagnetic environment- guidance
---|---|---
RF emissions CISPR 11| Group 1| This scale uses RF energy only for its internal function. Therefore, its RF emissions are very low and not likely to cause any interference in nearby

electronic equipment.

RF emissions CISPR 11| Class B| This scale is suitable for use in all establishments, including domestic establishments and those directly connected to the public low-voltage power supply network that supplies buildings used for domestic purposes.
Harmonic emissions IEC 61000-3-2| Class A
Voltage fluctuations/flicker emissions IEC 61000-3-3| Compliance

Guidance and manufacturer’s declaration – electromagnetic immunity.
The M-800 is intended for use in the electromagnetic environment specified below. The customer or the user of this scale should ensure that it is used in such an environment.

Guidance and manufacturer’s declaration – electromagnetic immunity.

3 Vrms

| Portable and mobile RF communications equipment should be used no closer to any part of the scale 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 manufacturer and d is the recommended separation distance in meters (m).

Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey, should be less than the compliance level in each frequency range.

Interference may occur in the vicinity of equipment marked with the following symbol:

---|---|---|---

NOTE
At 80 MHz and 800 MHz, the higher frequency range applies.

NOTE
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.

• Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcasts and TV broadcasts 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.
• Over the frequency range of 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

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.
