Removing and inserting a printed circuit board
To remove a printed circuit board in the transceiver unit, unfasten the securing screw
and unlock the lock lever.
To insert a printed circuit board, insert the board until the lock lever catches on the up-
per and lower projection, then push the lock lever inwards (see the following figure).
After the board is locked in place with the lock lever, confirm that the inside end of the
securing screw is firmly against the chassis, then fasten the securing screw. If the
screw is not firmly against the chassis, the board may be inserted incorrectly. Remove
and re-insert the board.
