Using Security Locking
The projector includes two security locking points to prevent its theft
when installed or used in public locations:
■ Security cable attachment. You can attach a commercially
available security cable as shown below to secure the projector to a
table or ceiling mount.
■ Kensington security slot. The security slot (located on the side
of the projector) is compatible with the MicroSaver security
systems manufactured by Kensington. You can purchase this lock
from Epson (see page 11).
