Reconfiguration Kit Twin VHF with Gantry Reconfiguration Kit Twin VHF mit Portal 137

Converting the HCU

If you have ordered the base adapter without HCU(s) you will have to convert the HCU(s). Proceed as

follows:

► Repeat this procedure for the second HCU, if necessary (for Twin only).

Installation

► Follow the removal instructions in reverse order for installation. Also observe the following instruc

tions:

► Loosen the screws (2) fastening the board.

► In addition, the board is fastened with the topmost of

both HCU screws (1). You also need to loosen this.

► Carefully pull the board down and off.

Make sure that the head adapter board is connected

to the head interface via a press-fit connection from

below.

► Loosen the two screws fastening the HCU on the

back of the board and carefully pull the HCU off the

base adapter.

CAUTION!

Washers and pins

Make sure that you do not lose the washers. Make a note

of the number of washers used for each screw, as this

may well differ. These will need to be fitted back in again

as well.

Make sure that you do not damage the pins under the

HCU.

CAUTION

Installation instructions

► Check the firmware and perform a download, if needed (see Service Manual).
