When installing a Remote Electronics Kit (REK4) the electronics panel and the cabi-
net that were originally shipped together should be connected together, otherwise the
anechoic calibration is lost. To help with this during installation, the serial number
shown on the electronics panel is also printed behind the woofer ring

. To remove the
woofer ring, carefully place your fingers on either side of the inside of the woofer ring,
press outwards, and then pull towards you. To refit the woofer ring, align the pegs with
the holes and gently push until the woofer ring is fully inserted.
