1. GENERAL INFORMATION
The WWG-2 large-size display is used to display mass from industrial scales
in challenging ambient conditions with strong external lighting (sunlight) and at
a great distance from the weighing indicator.
For use in harsh industrial environments, the display is housed in a stainless
steel housing. An additional bracket allows the display to be mounted on the
wall. The WWG-2 features a white diode backlight and a clear display
indicating digits of 4.4" (11.2 cm) in height. Communication with the weighing
indicator is established via the RS232 interface. The display is supplied with
230VAC.
2. WARRANTY CONDITIONS

3. MAINTENANCE
In order to clean the large-size display risk-free, it is necessary to disconnect
it from the mains.
3.1. Cleaning Stainless Steel Components
Avoid using cleansers containing any corrosive chemicals, e.g. bleach
(with chlorine). Do not use cleansers containing abrasive substances.

6
Always remove the dirt with a microfiber cloth. Do it to avoid damage
to the protective coating.
Daily cleaning routine (removal of small stains):
1. Remove the dirt with a cloth dipped in warm water.
2. For best results, add a little bit of dishwashing detergent.
3.2. Cleaning ABS Components
To clean dry surfaces and avoid smudging, use clean, non-colouring cloths
made of cellulose or cotton. You can use a solution of water and detergent
(soap, dishwashing detergent, glass cleaner).
Gently rub the dirty surface and let it dry. Repeat the cleaning process
if necessary.
In the case of hard to remove contamination, e.g. residues of adhesive, rubber,
resin, polyurethane foam, etc., you can use special cleaning agents based on
a mixture of aliphatic hydrocarbons that do not dissolve plastics.
We recommend conducting tests before using the cleanser on all surfaces.
Do not use cleansers containing abrasive substances.
4. SERVICE AND REPAIR
In the event of a problem with the device's proper operation, contact
the nearest manufacturer's service point.
In the case of any sign of damage, it is necessary
to disconnect the device from the mains immediately.
The damaged component must be replaced or repaired by
RADWAG service directly.
In the case of defects, deliver the faulty product to the manufacturer's service
point. If the product cannot be delivered to the manufacturer's service point, call
the service and report the defect. A repair scope and method will be set up.
The user is NOT ALLOWED to carry out any kind of repair on
the device himself/herself. Any attempt at device
modification, repair, etc. by unauthorised persons will result
in the loss of validity of manufacturer-issued certificates,
declarations, and warranty.
