Fix with glue
Note: Owing to Uniq Display, LED diode cable consists of IrDA diode of remote control too. Placing of IrDA
diode is described in particular chapter.
2.26.2. Replacement and interconnection of LED diode
Executions with except of AUO display has not lightguide. To power indication serves LED diode situated
in corner of front cover.
It is necessary prepare before replacement:
–
Pattex gun
–
tin and soldering
LED diode is in the cover fixed with Pattex. Just pull it out with sufficient of strenght. Fix it again with drop
of Pattex.
There is a resistor 220R 0,6W on the LED diode anode to reduce the voltage.
Note: Diode must be installed, so that no water can seep through diode hole into the device! Pattex must
cover all diode hole. Otherwise the IP54 protection class cannot be guaranteed.

2.26.3. Placing of IrDA diode
Uniq Display 150 has installed remote control IrDA diode in leg or tube holder. Diode is sticked with
Loctite 403 from inner side. Not the power glue not seep on diode lens and cause malfunction of IrDA signal
reading.
