2.01 Safety

The operators must read this user manual carefully, follow the direc-

tions in the manual and learn the correct procedures for the use and

maintenance of the digital scale.

These user instructions contain important information on the mounting, use

and maintenance of the digital scale.

The manufacturer assumes no liability for direct or indirect damages, includ-

ing loss of earnings or other commercial damage, which may be due to use

of the product that is not in accordance with what is described in this user

manual.

Save this user manual and the declaration of conformity for later use, and use

them when training personnel.

• Avoid overloading the digital scale beyond its maximum capacity

• Avoid sudden loading of the digital scale

• Do not use sharp or pointed objects to press the keys

• Do not try to open the digital scale

• Do not remove the seals on the digital scale

• The battery poles must not be short-circuited

• Do not submerge the digital scale in water or other liquids

• Perform regular maintenance and subsequent measurement checks (see

section 11.00)

NOTE: The medical equipment requires special precautions concerning elec-

tromagnetic compatibility, and must be installed and used with respect to the

information in accompanying documents.

ATTENTION

Mounting of the digital scale must be performed by qualied personnel, and

before use it must be checked that the di󰀨erent parts are mounted correctly,

such that the person is weighed in a safe and sensible manner. Incorrect

mounting may cause risks of falls and involve serious consequences for the

person.

After mounting of the digital scale and before weighing of the person, the person-

nel must ensure that:

• The weighing will be performed over “soft” items such as for example a mat-

tress, pillows, bed or other soft elements, in order to minimise the consequenc-

es of a possible accident

• The model RS digital scale and the sling are in the VERTICAL POSITION

• The personnel must ALWAYS follow and keep their focus on the sling and

the person during the lift in order to avoid swinging and possible move-

ments of the digital scale

• The ceiling hoist or the mobile lifter with digital scale and the person in the

sling must not be moving, relocated or turned during the weighing

• Once the weighing has been concluded, the sling must be taken o󰀨 the

person and the digital scale dismounted

Swinging and turning of the scale may cause incorrect weighing. The personnel

must therefore ensure that the person remains calm during the weighing.

Avoid swinging and sudden movements of the digital scale, which may

damage the scale and result in incorrect weighing.

• Always follow the applicable rules with the use of electrical components that

are subject to increased safety requirements.

• Incorrect installation will invalidate the warranty.

• The digital scale is intended for indoor use.

• Comply with the permissible room temperatures for operation.

• The digital scale complies with the requirements for electromagnetic

compatibility.

• The maximum values specied in the applicable standards must not be

exceeded.

• Avoid overloading the digital scale. Overloading will be indicated by an

audible signal.

2.02 Use

There are many di󰀨erent mounting possibilities with a digital scale, depend-

ing upon the situation in which it is being used. The most common manners

of mounting the digital scale are described below. A number of the mounting

combinations in the conguration table at the end of this chapter are illus-

trated.

1. Hook from ceiling hoist or mobile lifter

2. Quick release button on the digital scale’s top

3. Quick release button on the digital scale’s bottom

4. Adapter for mounting of lifting hanger

1. A. Mounting of the digital scale on a ceiling hoist GH1, GH3, GHZ or a

mobile lifter GL5, GL5.1

Fasten the digital scale to the hook on the ceiling hoist or the mobile lifter by

pressing on the quick release button (2) and fastening the hook (1).

B. Mounting of the digital scale on a ceiling hoist GH2 or a ”Universal”

oval hook

Fasten the digital scale to the hook on the ceiling hoist by opening the GH2

snap hook (1) or the oval hook and fasten the hook on the quick release

button (2).

C. Mounting of the digital scale on a mobile lifter GL

Fasten the digital scale to the mobile lifter using an adapter tted on the

mobile lifter’s bar.

Fasten the digital scale to the adapter (see page 11) on the mobile lifter by

pressing on the quick release button (2) and fastening the adapter.

2. Mounting of adapter hook from lifting hanger to the digital scale

Press on the quick release button (3) and fasten the adapter hook (4).

Fasten the lifting hanger by inserting the adapter hook (4) on the lifting hang-

er.

3. Attach the desired sling on the lifting hanger and reset the digital scale (see

section 4.00). The display will subsequently show 0.0.

4. Remove the sling from the hanger. Place the sling on the person and attach it

on the lifting hanger again.

5. Carefully lift the person. When the sling with the person is at rest and freely

suspended, the relevant weight will be shown on the display.

Important

Always reset the scale before weighing takes place.

Note:

The power saving function will automatically shut o󰀨 the display after 30 sec.

if the scale has no load. Can be changed (see section 7.00).

6. Carefully lower the person after the scale has been read.

Warning

This scale has been produced in order to weigh the person in connection

with him/her being relocated, for example between a bed and a chair. In con-

nection with reduced lifting height, it may be necessary to divide the process

in 2, weighing of the person and subsequent detachment of the scale, and

then performing the nal relocation, for example between a bed and chair.

The scale has not been produced for use in connection with transport of the

person. In the event of transport, the scale must be detached.

a) Field strengths from xed transmitters, such as base stations for radiotelephones

(mobile/wireless) and land mobile radios, amateur radio equipment, AM and FM radio

transmitters and TV broadcasting, cannot be estimated reliably theoretically. Consid-

er performing an electromagnetic eld survey in order to assess the electromagnetic

environment that is caused by xed radio frequency transmitters. If the measured eld

strength at the location where the device is being used exceeds the compliance level for

radio frequency energy that will be used, then you should observe the device in order to

check that its operation is normal. If abnormal operation is observed, further precautions

may be necessary, for example turning or relocating the device.

b) Over the frequency range from 150 kHz to 80 MHz the eld strength should be less

than 3 V/m.

Recommended distance between RS Digital scale and portable- and mobile radio fre-

quency-based communications equipment

The model RS digital scale is intended for use in an electromagnetic environment, where

radiated RF disruptions are under control. The customer or user of device may assist in

preventing electromagnetic disruptions by maintaining a minimum distance between por-

table and mobile RF communications equipment (transmitters) and the device as recom-

mended below, with respect to the communications equipment's maximum output power.

For transmitters with a rated maximum output power not mentioned above, the recom-

mended distance in metres (m) can be estimated using the formula that applies for the

transmitter frequency, where P is the transmitter's maximum rated output power in watts

(W) according to the manufacturer of the transmitter.

Note: At 80 MHz and 800 MHz the higher frequency range applies. It is possible that these

guidelines do not apply in all situations. Electromagnetic propagation is a󰀨ected by absorp-

tion and reection from buildings, objects and people.
