Communication mode
The wireless LAN of this projector supports both Ad hoc and Infrastructure
Communication modes.
Ad hoc communication mode
This is the transmission mode to communicate
between wireless LAN equipment.
This mode is applicable, for example, to a
presentation in the conference room, as it requires
no other facilities. This function can only be used if
the projector is in range of the computer’s wireless signals.
Ricoh does not guarantee the coverage of the radio wave in the form of figures. The
coverage varies depending on the performance of each wireless LAN equipment,
existence of obstacles or other wireless LAN equipment used by nearby working
groups, etc. The coverage is generally estimated on the assumption that wireless LAN
equipment be used in an unobstructed office or conference room.
Infrastructure communication mode
A mixed wireless and wired LAN can be created
via wireless LAN access points. (Communications
between wireless LAN devices are also allowed.)
Connecting to the rest of the world via a wired
LAN or the Internet generally requires a high level
of security.
Use the appropriate transmission mode for your
network environment.
Caution when using the wireless LAN functions
The Wireless LAN in this unit uses the 2.4 GHz waveband. If there is a similar wireless
LAN in the area, or a wireless device using the 2.4 GHz waveband, or a microwave oven,
the communication efficiency of this apparatus will be reduced, and may become unusable,
but it is not a fault. If this happens, check an area away from the current location that will
not cause radio interference to medical, industrial and public equipment, and change to
it, or stop using the unit.
