Changing frequency channel
If you are experiencing problems with the range or reliability this may be due to poor reader positioning, adjacent
interfering 125KHz or 2.4 GHz equipment, e.g. an adjacent wireless PC network. Please refer to the ‘Before you
install’ information regarding unit locations. If you are still unable to improve the system performance then you
may try an alternative 2.4 GHz channel using Switch 1. Power cycle the unit after any changes.
The system has 16 different channels available. The unit is set to channel 4 as this frequency is normally clear of
other device transmissions. This can be changed using a small at blade screwdriver. Take care not to contact the
circuit board with the screwdriver blade as this may damage components.
