Figure 4. Installing the LockIt Lacing Bracket
1. Plug the HDMI cable into the panel connector.
2. Loosen the HDMI connection mounting screw from the panel enough to allow the
LockIt lacing bracket to be placed over it. The screw does not have to be removed.
3. Place the LockIt lacing bracket on the screw and against the HDMI connector, then
tighten the screw to secure the bracket.
ATTENTION: Do not overtighten the HDMI connector mounting screw. The shield
to which it is fastened to is very thin and can easily be stripped.
4. Loosely place the included tie wrap around the HDMI connector and the LockIt lacing
bracket as shown.
5. While holding the connector securely against the lacing bracket, use pliers or a similar
tool to tighten the tie wrap, then remove any excess length.
