KEYPAD CONFIGURATION
Source Buttons
The K-4.4 Keypads come with a set of four Source Unit Labels that can be inserted under the Source
Button Key Caps to label the Source Buttons.
Figure 15 Keypad Button Labels
To configure the Keypad Source Buttons:
1.
With the keypad disconnected from the Controller, carefully remove the bezel, by pressing the bottom
of the bezel with one thumb and then pulling the bezel down and away from the chassis with two
fingers at the top of the bezel.
NOTE:
Keep the keypad facing up so the rubber membrane and source button key caps do not fall
off. If the membrane does come loose, carefully put it back in place, and do not touch the contacts on
the circuit board.
2.
Carefully remove the source button key caps.
3.
Carefully peel the appropriate Button Label off of the sheet provided. Place the label on top of the
rubber platform for the source button.
4.
Carefully slide the key cap down on top of the label and rubber platform until the key cap is firmly
positioned on top of the label and rubber platform.
5.
Repeat for all Source Buttons.
6.
Slide the lower bezel tabs into the lower bezel tab slots on the keypad chassis.
7.
Slowly press the top of the bezel toward the chassis checking the alignment of all buttons to the
bezel.
8.
When all buttons are aligned, snap the top bezel tabs to the keypad chassis.
9.
Press all buttons to confirm free movement of all buttons.
10.
Repeat for all keypads.
