block (marked L N E); brown to terminal L, blue to terminal N and yellow/green to terminal E.
(3) Connect the dc wires to the eight connector terminal block, red to terminal 1 and terminal 2 and
black to terminal 5 and terminal 6.

(5) Taking care not to damage the plastic supply guard, lower the power supply into position and
secure from the bottom half of the unit using two countersunk screws, previously removed, for
each power supply.
(6) Re-establish the ac and/or dc supplies.
(7) Switch power on at the radio using the rear mounted Power switch.
(8) Ensure the front panel Ready indicator is lit and the Alarm indicator is unlit.
