By choosing the WUNDER mod. W1090 Bluetooth professional electronic scale,
you have purchased a high precision instrument.
Since over 40 years WUNDER has placed its experience at the service of health.
This instrument is compliant with national standards in hospitals and clinics with
medical class I with measurement function and is calibrated in conformity with
accuracy class IIII. The instrument is characterised by the possibility of xing the
electronic terminal to the weighing platform by means of a column or else instal-
ling the terminal autonomously.
WUNDER reserves the right to modify its products as deemed convenient in order
to approve them without being committed to update this publication.

WEIGHING OPERATION
- Before reading detailed instructions on how to use all the weighing functions
that are built into your scale, please read the following important guidelines:
- Always be sure that the display shows `Zero` before use, if it doesn’t then
please press the ZERO key.
- The Professional Medical scale is designed to detect when a stable weight
is achieved, the indicator will `bleep` twice to indicate a stable weight value,
your reading should be taken at this point.
DISPOSING OF THE SCALE
- This product is not to be treated as regular household waste, but should be
handed in to an electrical/electronic equipment recycling centre.
- You can obtain further details from your local council, your municipal waste
disposal company or the rm which you purchased the product

Manufacturer’s guide and declaration - Electromagnetic emissions
The W1090 scale is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer/user of the W1090 scale
can help prevent electromagnetic interference by maintaining a minimum di-
stance between portable and mobile RF communications equipment (transmit-
ters) and the W1090 scale as recommended below, according to the maximum
output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the
recommended separation distance d in metres (m) can be estimated using the
equation applicable to the frequency of the transmitter, where p is the maximum
output power rating of the transmitter in watts (W) according to the transmitter
manufacturer.
NOTE1 At 80 MHz and 800 MHz, the separation distance for the higher
frequency range applies.

ERROR MESSAGES AND SOLUTIONS
ERROR REASON SOLUTION
lo Low Battery:
Means that the charge of the bat-
tery is too low to use
Please replace a new battery or
plug the AC adaptor
Err Overload:
The total load exceeds the maxi-
mum capacity
Please reduce the load
weight and try again
Err.H Counting error (too high):
Indicates that the signal from the
load cell/s is too high
This error is normally caused
by a serious fault on the sca-
le such as a faulty load cell or
wiring. Please contact the local
service representative.
Err.L Counting error (too low):
Indicates that the signal from the
load cell/s is too low
This error is normally caused
by a serious fault on the sca-
le such as a faulty load cell or
wiring. Please contact the local
service representative.
00000 Zero count over calibration
zero range +10%
while power ON
Please re-calibrate the scale
00000
Zero count under calibration
zero range -10%
while power ON
Please re-calibrate the scale
Err.P EEPROM Error:
Indicates that there is a fault with
the scales software
This error is normally caused
by a serious fault on the sca-
le such as a faulty load cell or
wiring. Please contact the local
service representative.
Self-checking Tips:
Some functional defects can be identied and maintained by users as listed below:
Power-ON failure
1. Check if the main power adaptor has not plugged onto the scale properly
2. Check if the battery power is running low - Replace with new batteries

Waste disposal EU 2012/19/UE
This product complies with the Directive 2012/19/UE. The symbol of the cros-
sed-out waste bin on the appliance indicates that the product, needing to be
treated separately from household waste, at the end of its useful life must be
completed in a separate collection facility for electric and electronic appliances
or returned to the dealer upon purchase of a new equivalent appliance. The user
is responsible for bringing the appliance to an appropriate collection structure at
the end of its life. Appropriate separate collection and sending the appliance for
recycling, treatment and environmentally compatible waste disposal contributes
to avoid possible negative eects on the environment and health and favours the
recycling of the materials the product is made of.
For more detailed information regarding available collection systems, contact
your local waste disposal service or the shop where the product was purchased.
As consumers, you are obliged by law to return used or dead batteries. You may
deposit old batteries at public collection spots in your town or else with any bat-
tery dealer who has placed specic collectors for this purpose. Even when scrap-
ping electric and electronic appliances, they must be removed and deposited in
specic collectors.
