3 Basic directions (general information) 3.1 Intended use The scale is used to determine weight of babies in lying positions and intended for private use only. The use of this scale in health service is forbidden. To carry out weighing, lay down a child on the scale plate. The weighing value can be read off after a stable weighing value has been obtained. Before any use, the scale must be checked for correct condition by the authorised person.
3.3 Guarantee The guarantee shall become void in the event of the following: non-observation of our guidelines in the Operating Instructions, use outside the described applications, alteration to or opening of the device, mechanical damage or damage caused by media, liquids, usual wear and tear, inappropriate erection or electric installation, overloading of the measuring equipment, allowing the scale to fall down. 3.
5 Transport and storage 5.1 Check upon delivery Please check the packaging immediately upon delivery and the device during unpacking for any visible signs of external damage. 5.2 Packaging Please keep all parts of the original packaging in case it should be necessary to return items at any time. Only the original packaging should be used for return shipments. Before any shipment, disconnect all cables and loose/movable parts. Install transport protection elements (if any).
6.2 Unpacking Carefully remove individual scale parts or the whole scale from its packaging and position the scale in its intended working location. When the mains adapter is used, be careful not to cause the danger of falling over the power cable. 6.2.1 Scale positioning Pay attention that the scale plate is precisely levelled. 6.2.2 List of items delivered Standard accessories: 6.3 • Operating Instructions • Batteries (4 x AA 1.
6.5 Adjustment As the acceleration value due to gravity is not the same at every location on earth, each balance must be coordinated - in compliance with the underlying physical weighing principle - to the existing acceleration due to gravity at its place of location ( only if the balance has not already been adjusted to the location in the factory). This adjustment process must be carried out during the initial start-up, after change in location and variation of surrounding temperature.
7 Operation 7.1 Display 7.2 Handling The scale is provided with only one key (ON/OFF). The purpose of this key is to switch on the scale, and switch it off by longer holding the pressed key when the scale is switched on. Height of digits on the 4-position LCD display is 15 mm. 8 Using the scale 1. When batteries are inserted and the ON/OFF key is pressed shortly, the test of all display segments is carried out and then the 0.00 display will be shown. 2.
9 Error messages EE: No possibility of displaying the weighing value. It occurs e.g. when a weight is removed after finishing the automatic taring. Remove a weight, switch off the scale and switch it on again. 10 Service, maintenance, disposal 10.1 Cleaning Do not use aggressive cleaning agents (solvents or similar agents), but a cloth dampened with mild soap suds or cleaning agent. Ensure that no liquid penetrates into the device and wipe the device with a dry soft cloth.
11 Troubleshooting The scale should be switched off for a short time following an interruption in the program sequence and disconnected from mains supply. It is then necessary to repeat the weighing process from the beginning. Help: Interruption Possible cause Weight display is not illuminated. • The scale is not switched on. • • Batteries are incorrectly inserted or discharged No batteries.
