seca 685 Instruction manual and guarantee

DEVICE DESCRIPTION

1.1 Intended use
Electronic multi-functional scale seca 685 is mainly used in hospitals, medical practices and in-patient care facilities in accordance with national regulations.
The scale is for conventional determination of weight and establishment of general state of nutrition; it assists the physician supervising treatment in making a diagnosis or deciding on a course of treatment.
To make an accurate diagnosis, however, other specific examinations have to be ordered by the physician and their results taken into account, in addition to determining a weight value.
1.2 Description of function
In addition to conventional determination of weight, the seca 685 provides a function for determining body mass index. To this end, height is entered on the keypad and the body mass index associated with the weight value is calculated automatically. Length measuring devices from the seca 360° wireless system can transmit height to the seca 685 wirelessly.
Via the seca 360° wireless wireless network, measuring results can be transmitted wirelessly to a seca wireless printer or to a PC equipped with seca analytics PC software and the seca USB wireless adapter.
The seca 685 can be moved on casters.
Use the scale only for the purpose named in the section entitled “Intended use” on page 59.
1.3 User qualification
Assembly
Devices that are shipped partially assembled may only be mounted by sufficiently qualified persons such as specialist dealers, hospital technicians or seca service technicians.
Operation
The device may only be operated by healthcare professionals.

THE SECA 360° WIRELESS NETWORK

6.1 Introduction
This device is equipped with a wireless module. The wireless module allows wireless transmission of measurement results for evaluation and documentation.
Data can be transmitted to the following devices:

• seca wireless printer
• PC with USB wireless adapter

seca wireless groups
The seca 360° wireless network operates with wireless groups. A wireless group is a virtual group of transmitters and receivers. If several transmitters and receivers of the same type are going to be operated, up to 3 wireless groups (0, 1, 2) can be set up with this device.
Setting up several wireless groups ensures the reliable transmission of correctly-addressed measured values if you wish to use several examination rooms each with comparable equipment.
The maximum distance between transmitters and receivers is approx. 10 meters. Certain local circumstances such as the thickness and type of walls, may reduce the range.
The following combination of devices is possible for each wireless group:

• 1 baby scale
• 1 personal scale
• 1 length measuring rod
• 1 seca wireless printer
• 1 PC with seca USB wireless adapter

Channels
Within a wireless group, devices communicate with each other on three channels (C1, C2, C3). This guarantees that data are transmitted reliably and without interference.
If you set up a wireless group with this scale, the device suggests three channels which will ensure optimal data transmission. We recommend adopting the channel numbers suggested.
You can also manually select the channel numbers (0 to 99), for example if you wish to set up several wireless groups.
To ensure interference-free data transmission, the channels must be spaced sufficiently far apart. We recommend a spacing of min. 30 between channel numbers. Each channel number may only be used for one channel.
Example configuration for channel numbers when setting up 3 wireless groups within a medical practice:

• wireless group 0: C1=_0, C2=30, C3=60
• wireless group 1: C1=10, C2=40, C3=70
• wireless group 2: C1=20, C2=50, C3=80

Device detection
If you set up a wireless group with the scale, it searches for other active devices from the seca 360° wireless system. The devices detected are shown in the display of the scale in the form of modules (e.g. MO 3). The numbers have the following meaning:

• 1: personal scale
• 2: length measuring rod
• 3: wireless printer
• 4: PC with seca USB wireless adapter
• 7: baby scale
• 5, 6 and 8-12: reserved for system expansion

6.2 Operating the scale in a wireless group (menu)
All the functions you need to operate the device in a seca wireless group can be found in the “rF” submenu. Information for navigating in the menu can be found on page 88.
