IMPORTANT
For combined approval types
Once a device of multiple approval type is
installed, it should not be re-installed using any
other approval types. Apply a permanent mark
in the check box of the selected approval type
onthecerticationlabelonthetransmitterto
distinguish it from unused approval types.
IMPORTANT
All the blind plugs which accompany the EJX/
EJA-E transmitters upon shipment from the
factoryarecertiedbytheapplicableagencyin
combination with those transmitters. The plugs
