Wall Mounting the Scale

You can hang the Patient Transfer Scale on the wall either horizontally or vertically, using the hooks provided. Your hooks will need to be positioned exactly 1400mm or 610mm apart, centre to centre, depending on orientation. Use the Patient Transfer Scale and the hooks to determine the positioning of the hooks on the wall, and mark drill holes. Drill holes should be exactly 1400mm or 610mm apart, as per above. Drill two 6.5mm the holes for each hook. Affix the hooks to the wall using the screws and wall plugs provided, and use the plastic covers to hide the screwheads. Your Patient Transfer Scale can now be hung on the wall.

Recharging the Scale

We recommend fully charging the scale before first use. To fully charge the scale please allow 8 hours.
When the low battery indicator on the LCD display indicates that the scale needs recharging, move the M-999 to a location where it can be charged. You will find the charging port on the underside of the scale.The port for the charging cable is magnetic. Clip the end of the cable in place and plug the other end of the cable into a power socket. Please do not use any form of charging cable other than the one supplied with the scale. The scale cannot be used whilst recharging.

Setting up the Scale

With the scale switched off, press and hold until the display shows , then press 3 times. You will enter Setup for auto power-off, buzzer and backlight.
Auto off time: 30m/60m/off
Buzzer: On/Off
Backlight: ON/OFFTo confirm the settings, please press HOLD/UNIT when shows on the display.

Preparing to use the Scale

The Patient Transfer Scale should be used in line with current moving and handling policies. Essentially, it should be used in the same way you would use a transfer board, taking into account of course that you will need to pause for a few seconds during the transfer process, to allow the scale to capture the patient’s weight.

• The Patient Transfer Weighing Scale should only be used by trained professionals.
  Ensure brakes on castors are applied before you begin the transfer process.

• Ensure that trolley/bed frames are touching before you start the transfer process.

• There should be no more than 200mm between mattresses. There should also be 200mm or more of the Patient Transfer Scale on each bed or trolley before use.

• When transferring, the two surfaces must be of similar height. A tilt of less than 3% (one side raised by around 25mm) is ok; a tilt greater than this will affect the scale’s accuracy. To avoid showing an inaccurate reading, the scale will display an error message if tilt exceeds 3% (see Error Messages).

• Guidance for safe use can also be found on the scale itself (see next page).

CAUTION

1. Transfer between surfaces of similar height
2. Check the scale for damage before use
3. Do not overload. Maximum capacity 250kg / 550Ibs
4. The wheels of the trolley or bed must be locked before use
5. The distance from bed to bed, or trolley to bed, must be no more than 20cm / 8 inches
6. The Patient Transfer Scale must have a minimum of 20cm / 8 inches on each bed or trolley and bed

Operation: Basic Functions

Switching the Scale on To switch the scale on, press the ON/OFF/ZERO button. When the display shows 0.0 the scale is ready to use.
Switching the Scale off Press and hold ON/OFF/ZERO button for three seconds to power the scale down.
Setting the Scale to Zero
If for any reason the scale shows a reading other than 0.0 it can be reset to zero. Press the ON/OFF/ZERO button once and the scale will return to 0.0.

Operation: Advanced Functions

Using the Hold Function The scale’s Hold function stabilises the weight reading on the display, allowing you to take an accurate reading without fluctuations. With a patient on the scale, press HOLD/UNIT. The display will show ‘HOLD’.
NB: Alternatively, you can activate the Hold function before the patient is on the scale.
When the scale has determined the weight of the patient, a stable weight reading will show. This will remain on the display after the patient has left the scale. Press HOLD/UNIT to disable the Hold function.

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 MEDICAL SCALE M-999 is used exceeds the applicable RF compliance level above, the MEDICAL SCALE M-999 should be observed to verify normal operation. If abnormal performance is observed, additional measures my be necessary, such as re- orienting or relocating the MEDICAL SCALE M-999.
b  Over the frequency range 150 kHz to 80 MHz, field strengths should be les than 3 V/m.
Recommended separation distance between portable and mobile RF communications
equipment and the MEDICAL SCALE

The MEDICAL SCALE M-999 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the MEDICAL SCALE M-999 can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the MEDICAL SCALE M-999 as recommended below, according to the maximum output power of the communications equipment.
