Unlock the cabinet lock at the bottom of the BTS.
Remove the cover by sliding it upwards to disengage the hooks at the side
of the cover from the locking guides on the BTS chassis.
When the cover is free, pull it away from the cabinet and hang it on the
hook at the top left side of the chassis.
You can also remove the cover completely to place it on the floor. Remove
the safety strap before pulling the cover away (see Figure 14).
