Instruction book, IQAN- MD3
Display
Brightness
The brightness is easily adjusted by pressing the ’menu’ button and following the
prompts to the backlight settings section.
Burn-in
The IQAN-MD3 TFT display, like other computer screens can have a ghost picture
occur if a static image is left on the display for extended periods of time. For the best
viewing over the life of the product we recommend using the screensaver functionality.

OTICE
To avoid burn-in, use the screensaver on the display.
Maintenance
The 3.5" transflective display is a high quality viewing interface and reasonable care
should be taken to maintain it.
The display can be cleaned with an LCD cleaning solution found in many stores. Use a
lightly dampened lint-free, non-abrasive cloth when cleaning the display.

To avoid scratches, do not wipe or clean a dry display.
Polarization
The MD3 screen has polarizers, the TFT is defined by its manufacturer as portrait
mode, but we have tilted it to have a landscape mode display. When wearing polarized
sunglasses, the effect is for the screen to be unreadable due to the conflicting
polarizations. This is easily solved by applying a film to the display. One type of film
that is proven to work is NuShield DayVue anti-reflective overlay film.
Environment Specification
IQAN-MD3 is a hardened module suitable for outdoor use. However, concentrating
cleaning jets on the control surface of the IQAN-MD3 can cause a degradation of the
finishing and should be avoided.

OTICE
To keep the unit’s buttons looking their best, do not blast the control surface with
cleaning jets.
Back of unit
If the rear surface of the IQAN-MD3 unit is exposed and will be subjected to high
pressure steam cleaning, care should be taken around the connector assemblies. The
Deutsch DTM connectors are IP67 rated which is suitable for any type of outdoor
conditions. However, concentrating the cleaning jets on the connectors of the IQAN-
MD3 can cause damage to the connector seals or wire insulation and should be
avoided. Use of shielding is recommended to block high pressure cleaning jets, if the
rear of the unit is exposed.

OTICE
To avoid damaging the connector seals or wire insulation, do not blast the connectors
with cleaning jets.
