1. Congratulations!
By purchasing the seca 808 electronic
personal scale, you have acquired a high-
ly-accurate and sturdy piece of equip-
ment.
seca has been putting its experience at
the service of health for over 150 years
now, and as market leader in many coun-
tries of the world, is always setting new
standards with its innovative develop-
ments for weighing and measuring.
In addition to determining weight conven-
tionally, the seca 808 can also calculate
Body Mass Index and body composition
(proportion of body tissue made up of fat
and water). For this purpose, an imper-
ceptible, harmless AC current is passed
through the body.
The weight display can be switched be-
tween kilogrammes (kg), pounds (lb) and
stones (st). Weight is determined within a
few seconds.
The scale is of a very sturdy construction
and will give you long and loyal service. It
is easy to operate and the large display is
easy to read.
2. Safety
Before using the new scale, please take a little time to read the following safety instruc-
tions.
• Follow the safety instructions in the in-
struction manual.
• Keep the operating manual and the
declaration of conformity contained
therein in a safe place.
•You must not use this scale if you wear
a cardiac pacemaker, an insulin pump
or other electronically-controlled medi-
cal device. Their function could be im-
paired.
• Do not expose the scale to excessive
moisture.
•Do not drop the scale or subject it to vi-
olent shocks.
• Have repairs carried out exclusively by
authorised persons.
•Use only the type of battery stated (see
“Changing the batteries” on page 17).
3. Before you start…
Unpacking
Remove the packaging and place the scale on a firm, level surface.

Model 808 11
GB
Power supply
The scale is powered exclusively by batteries.
The LC display has a low power consumption – 8.000 weighing operations can be per-
formed with one set of batteries. When or bAtt appear in the display, you should
change the batteries. You require 4 AAA-type 1.5 V batteries.
All the illustrations are on the foldout flap at the front.
–Carefully turn over the scale so that the
base of the scale is accessible (see Fig.
3).
–Push the battery compartment closure
towards “Battery” and open the cover.
–Insert the new batteries in the battery
compartment.
Check that the polarity is correct.
– Close the cover.
–Then turn the scale back up the right
way.
Switching the weight display
The weight display can be switched between kilogrammes (kg) and pounds (lb) or be-
tween kilogrammes (kg) and stones (st) (see Fig. 2). Once you switch back on, weighing
will be performed using the new unit of measurement.
4. Setting up and aligning the scale
– Place the scale on a level surface.
–Ensure that only the feet of the scale
are in contact with the floor. The scale
may not be in contact at any other
point.
–If an uneven floor (e.g. thick-pile carpet)
contacts the base of the scale, push on
the carpet feet supplied (see Fig. 5).
5. Operation
Simple Weighing
–Step gently onto the scale (see Fig. 4).
The vibration switch starts the scale.
se(a, 8.8.8.8.8. and 0.0 appear consec-
utively in the display. The scale is then
automatically set to zero and ready to
use.
–If necessary, switch the weight display
(see “Switching the weight display” on
page 11).
– Stand on the scale and keep still.
Once weight has been determined, the
scale will also try to measure body
composition, which can be seen by the
symbol o moving across the display.
You can now simply get off the scale
(the scale will briefly show an error mes-
sage).
–Read the weighing result off the digital
display.
–If a load greater than 150 kg or 330.6 lb
is placed on the scale, St0P appears in
the display.
Automatic switch-off/economy mode
The scale switches off automatically after 20 seconds.

Weighing with measurement of BMI, body fat and body water
The seca 808 can also calculate the following body data in addition to weight: Body Mass
Index, body fat and body water proportion. For this purpose, an imperceptible, harmless
AC electric current is passed through the body and the measured values classified by
weight, gender, build and height. These data must previously have been entered in the
scale (see “Storing personal data” on page 12).
So that your values are determined correctly and are comparable with one another over
several days, please note the following instructions:
• You should perform the measurement
barefoot, otherwise there is insufficient
contact with the sensors (in this case
Err 2 will appear in the display). If you
have very dry skin, moisten your feet
slightly to improve conductivity.
• Stand as still as possible during meas-
urement.
• Position both feet so that they are as
much in contact with the sensors as
possible (see Fig. 6).
• Enter your height as exactly as possi-
ble. An error of just 2.5 cm will lead to
a deviation of 1 litre body water in the
calculation!
• Wherever possible, perform the meas-
urements each day at the same time
and under the same conditions, e.g. 15
minutes after getting up. Measure-
ments taken directly after sleeping give
implausible results, because body wa-
ter is distributed differently throughout
the body during sleep.
• Measurements taken directly after
strenuous physical exercise also give
implausible results. Take a relatively
long break (approximately 2-3 hours)
before measuring.
•Heavy meals or drinking of alcohol also
give implausible results.
• In the following cases, exact measure-
ments cannot be performed using the
seca 808: during pregnancy or if your
body contains medical implants such
as artificial joints, metal plates or
screws. In such cases, you should
have your doctor carry out a differential
diagnostic examination to obtain cor-
rect results.
Storing personal data
The seca 808 can store personal data for up to four different people. In addition, it is pos-
sible to perform a measurement in so-called Guest Mode (see “Measuring in Guest Mode”
on page 14). The four personal memories are each assigned to one of the four keys
MENU, ▲, ▼or SET, and can subsequently be selected using these keys when the scale
is switched on.
–Switch on the scale using the one of the
four keys (MENU, ▲, ▼or SET) to the
memory of which the personal data is
to be assigned.
se(a, 8.8.8.8.8. and 0.0 appear consec-
utively in the display. The scale is then
automatically set to zero and ready to
use. The display likewise shows the
symbol for the selected personal mem-
ory, e.g. .
–Keep the MENU key depressed until
HEIGHT appears in the display.
The display will show the most recently-
entered height.
–You can change the value in the incre-
ments shown by the graduations in the
display using arrow keys ▲and ▼.
–Once the correct value has been set,
briefly press the SET key.
The menu for gender and build
appears.
–Use arrow keys ▲and ▼to select your
gender and your build:
MALE NORMAL: male, normal build,
(exercising a maximum of twice a week
for 30 minutes),

Model 808 13
GB
FEMALE NORMAL: female, normal
build, (exercising a maximum of twice a
week for 30 minutes),
MALE ATHLETIC: male and athletic,
FEMALE ATHLETIC: female and
athletic.
–Confirm your selection by briefly press-
ing the SET key.
The menu for entering age appears.
–You can increase or decrease the value
using arrow keys ▲and ▼.
–Once the correct value has been set,
briefly press the SET key.
This concludes data entry for the per-
sonal data for one person.
Measuring with automatic person recognition
The seca 808 can use the weight to recognise whether the person standing on the scale
matches one of the stored sets of data in the four people memories. So it is not always
necessary to bend down to switch on the scale using one of the keys. To do this, the
measured weight is compared with the stored weights and, if it is within a certain toler-
ance, it is then linked to the appropriate personal memory. The current weight is then
stored again and used as the basis for subsequent measurements. As a result, the scale
is always updated if you lose weight continuously - while on a diet, for example.
Note:
When you get on the scale the first time after storing your personal data, you must first
switch on the scale using the key assigned to your data. The scale can then assign your
weight to your personal data.
–Step gently onto the scale. The vibra-
tion switch starts the scale.
se(a, 8.8.8.8.8. and 0.0 appear consec-
utively in the display. The scale is then
automatically set to zero and ready to
use.
–Step onto the scale barefoot and stand
still (see Fig. 6)
The scale measures your weight and
subsequently starts measuring the elec-
trical resistance of your body tissue.
While the measurement is being taken,
the symbol omoves across the display.
–After measurement, the scale com-
pares the measured weight with the
stored weights. If it cannot clearly as-
sign it, all personal memory symbols for
which the weights stored are close to
the measured weight flash on the dis-
play.
–If the scale cannot clearly assign your
weight, now press the key (MENU, ▲,
▼or SET) which is assigned to your
personal data.
–Following successful measurement,
the values for BMI, body fat and body
water are displayed three times con-
secutively. The scale then switches off.
–Compare your values with the catego-
ries on pages 14 and 15.
Note:
If your determined weight is close to the stored weight of another person, it could be the
case that your measured values are assigned to a different personal memory. Check
whether the correct personal memory symbol is being displayed during the measurement.
If necessary, switch on the scale using the MENU, ▲, ▼or SET key assigned to your
personal memory before measuring if automatic person recognition does not work.

Measuring in Guest Mode
If all personal memories are already occupied, or if you would like to obtain one-off values
for BMI, body fat and body water for another person, you can perform the measurement
in so-called Guest Mode.:
–Switch on the scale by pressing the
MENU and SET keys simultaneously.
se(a, 8.8.8.8.8. and 0.0 appear consec-
utively in the display. The scale is then
automatically set to zero and the dis-
play shows GUEST.
–Keep the MENU key depressed until
HEIGHT appears in the display.
The display will show the last height
entered.
–You can change the value in the incre-
ments shown by the graduations in the
display using arrow keys ▲and ▼.
–Once the correct value has been set,
briefly press the SET key.
The menu for gender and build ap-
pears.
–Use arrow keys ▲and ▼to select your
gender and your build:
MALE NORMAL: male, normal build,
(exercising a maximum of twice a week
for 30 minutes),
FEMALE NORMAL: female, normal
build, (exercising a maximum of twice a
week for 30 minutes),
MALE ATHLETIC: male and athletic,
FEMALE ATHLETIC: female and athlet-
ic.
–Confirm your selection by briefly press-
ing the SET key.
The menu for entering age appears.
–You can increase or decrease the value
using arrow keys ▲and ▼.
–Once the correct value has been set,
briefly press the SET key.
This concludes data entry for the per-
sonal data for a guest.
Step onto the scale barefoot and stand
still (see Fig. 6). The scale determines
your weight and subsequently meas-
ures the electrical resistance of your
body tissue. During measuring, the
symbol omoves across the display.
–After successful measurement, the val-
ues for BMI, body fat and body water
are displayed three times consecutive-
ly. The scale then switches off.
–Compare your values with the catego-
ries on pages 14 and 15.
Evaluation of body fat and body water values
The body fat and body water values shown as a percentage of body weight below are
guideline values from the World Health Organisation (WHO).
Body fat:
Women
Age Underweight Healthy Zone Overweight Obese
Age 20 – 40 below 21% 21 – 33% 33 – 39% above 39%
Age 41 – 60 below 23% 23 – 35% 35 – 40% above 40%
Age 61 – 79 below 24% 24 – 36% 36 – 42% above 42%
Men
Age Underweight Healthy Zone Overweight Obese
Age 20 – 40 below 8% 8 – 19% 19 – 25% above 25%
Age 41 – 60 below 11% 11 – 22% 22 – 27% above 27%
Age 61 – 79 below 13% 13 – 25% 25 – 30% above 30%

Model 808 15
GB
Body water
Note:
People with a high body fat value very often have a body water value below that of the
WHO guidelines. Sportsmen and women with little body fat and high muscle mass often
exhibit values above these guidelines. In infants, water makes up 75 % of body weight.
This proportion then drops to 65 % by the end of the growth period and in old age is near-
er 55 %. (Source: Schmidt, Thews, Physiologie des Menschen [Human physiology], 25th
edition, Springer-Verlag in Berlin and Heidelberg, 1993).
The measured values will only give indications of possible irregularities in the water and
fat values of your body. The precision of the measurement depends on various influenc-
ing factors. If you notice deviations from the standard values, please ask your doctor for
a differential diagnostic examination.
Evaluating Body Mass Index for adults:
Compare the value determined with the categories quoted below which correspond to
those used by WHO, 2000.
• BMI below 18.5:
Warning, this patient weighs too little. There could be a tendency to anorexia. An in-
crease in weight is recommended to improve well-being and performance. If in doubt,
consult a specialist.
• BMI between 18.5 and 24.9:
The patient is of a normal weight. He can stay as he his.
• BMI between 25 and 30 (pre-obese):
The patient is slightly to moderately overweight. He should cut his weight if he is
already ill (e.g. diabetes, hypertension, gout, fat metabolism disorders).
• BMI over 30:
Weight reduction is essential. Metabolism, cardiovascular system and bones are all
under strain. A consistent diet, plenty of movement and behavioural training are all
recommended. If in doubt, consult a specialist.
6. Cleaning
Clean the surface and the housing as required using a domestic cleaning agent or commer-
cially-available disinfectant. Follow the manufacturer’s instructions.
Under no circumstances use abrasive or acid cleaners, white spirit, benzene or the like for
cleaning. Such substances can damage the high-quality surfaces.
Women 50 – 55%
Men 60 – 65%
Children 65 – 75%

7. What do I do if…
… no weight display comes on?
– Is the scale switched on?
– Check the batteries.
… 0.0 does not appear before weighing?
–Start the scale again after it switches off automatically – there must not be any load on
the scale – and only its feet should be in contact with the floor.
... the message Err 2 appears when measuring body fat and body water values?
–You should carry out the measurement barefoot, otherwise there is insufficient contact
with the sensors. If you have very dry skin, moisten your feet slightly to improve con-
ductivity.
... the values for body fat and body water deviate significantly from the standard
values?
– Stand as still as possible during measurement.
– Place both feet as completely on the sensors as possible (see Fig. 6).
–Have you entered your height correctly? Switch on the scale with the key assigned to
your personal memory and then press one of the arrow keys ▲and ▼. The symbol for
your personal memory will flash and the entered data will be shown. Check this and
amend if necessary (see “Storing personal data” on page 12).
–In the following cases, measurement will give implausible results: during pregnancy or
if your body contains medical implants such as artificial joints, metal plates or screws.
In such cases, you should have your doctor carry out a differential diagnostic exami-
nation to obtain correct results.
– People with a high body fat value very often have a below-average body water value.
–Very athletic people with little body fat and high muscle mass often exhibit values
above the guidelines. In this case, select the ‘Athletic’ option for your build.
... the values for body fat and body water deviate significantly between different
measurements?
–Wherever possible, perform measurements each day at the same time and under the
same conditions, e.g. 15 minutes after getting up.
–Measurements taken directly after sleeping give implausible results because body wa-
ter is distributed differently throughout the body during sleep.
–Measurements taken directly after strenuous physical exercise also give implausible re-
sults. Take a relatively long break before measuring.
– A heavy meal or drinking alcohol also give implausible results.
… one segment is illuminated constantly or not at all?
– The relevant segment has a fault. Inform Servicing.
… the display shows ?
– Battery voltage is running low. Change the batteries in the next few days.
… batt appears in the display?
– Batteries are empty. Put in new batteries.
… St0p appears in the display?
– Maximum load has been exceeded.
