Surface Mounting

To surface mount the master clock:

1.Place the master clock on its back with the display unit facing up and the key pad to the right.

2.Remove the two screws at the top of the display unit mounting plate.

3.Lift the display unit up and away from the backbox. Two rivets at the bottom of the cover will prevent you from lifting it straight up.

4.Unplug the ribbon cable from the back of the display unit to disconnect it from the power supply.

6.Making sure they are level, place two anchors 10 inches (25.4 cm) apart on the wall where the clock is to be mounted. Use the appropriate anchors for the wall.

7.Screw two #8 screws into the wall anchors.

8.If needed, place two wall anchors 5 inches (12.7 cm) below the first two screws, to accommodate the other two mounting screws.

9.Hang the power supply onto the top two screws using the keyholes on the back.

10.Screw two more #8 screws through the two holes at the bottom of the power supply into the wall anchors.

11.Wire the clock. (See Wiring the Master Clock on page 1-8.)

12.Reconnect the ribbon cable.

13.Replace the display unit using the two screws removed in step 2.
