3-1  Attaching the
Ferrite Core
Before using the AC adapter, attach the provided fer-
rite core to the cord in the position shown below.
Otherwise the AC adapter may cause signal interfer-
ence.
3-2  Selecting an
Installation
Site
The installation site for the wireless access point
must be selected carefully in order to avoid signal
interference and reductions in transmission speed
and range.
Observe the following guidelines when selecting the
location.
Select a location with as clear a line of sight as possi-
ble (i.e., as high as possible). 
Select a stable, level surface that is free of vibrations
and the danger of the unit falling.
Also observe the following:
• Do not place objects on top of the unit or stack units
on top of one another.
• Radio signals will pass through walls and glass but
not through metal. Concrete walls may be reinforced
with steel or other metal material that will block the
signal.
• The transmission range is widest in an open space.
However, the signal may be reflected from the large
metal walls in such a location as a warehouse. 
• Floors generally have steel girders and are installed
with metal fire protection material. Consequently,
communication between different floors is often not
possible.
• Do not install in a location exposed to intense radio
waves (such as near a wireless station) or intense
electromagnetic radiation (such as near a radio trans-
mission tower). 
Connect the ferrite core close to 
the DC plug. Wrap the cord once 
around the ferrite core and close 
the ferrite cord until it locks with a 
clicking sound. 
*Supplied AC adapter may 
differ depends on version.
[NOTE]
The transmission range
varies somewhat depending
on the installation location.
Use the line-of-sight dis-
tances indicated below as
guidelines when using an
SL-1100 or SL-1105 wireless
LAN card. 
Indoors
: approx. 50 m
Outdoors : approx. 150 m
When transmission speed is
11 Mbps
Indoors
: approx. 30 m
Outdoors : approx. 70 m
