1. For uniform brightness, equal current (10-20 mA) must be given for all segments with 2 volts supply. Choose appropriate resistor for uniform brightness ( R= { Vs - Vf } / IF) .
2. For cleaning, IP alcohol can be used but should not be in contact with the surface for more than 1 minute.
3. Do not bend the pins after soldering. If required, it may be done before soldering only.
4. Soldering rod should be kept away from the body of the display.
