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 .4 GHz waveband.  If there is a similar wireless 
LAN in the area, or a wireless device using the .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.
