• Please only use the screws (M3*16 tapping screw) provided with the kit to mount the Host to the ceiling.
• Please see Positioning the Host antennas on page 16 for guidelines on positioning the antenna to maximize
signal reception.
12 Installation
Attaching the Host to a ceiling mount
If the display is mounted on the ceiling:
1. Attach the Host to the ceiling mount using the provided velcro strap.
2. Fix the Host to the mounting holder.
3. Use the supplied velcro to fix the mounting holder and the Host to the ceiling mount as shown
in the illustration.
• Please only use the velcro strap (300(L)mm*25(W)mm) provided with the kit to mount the Host to a ceiling
mount.
• Please see Positioning the Host antennas on page 16 for guidelines on positioning the antenna to maximize
signal reception.
Placing the Host on a table
If your display is placed on a table, first attach the lid of to the Host in the following the process
described below:
1. Align the lid over the bottom of Host so that the triangle on the bottom side of the lid is aligned
to the triangle in the lid compartment, then insert the lid into the lid compartment.
13 Installation
2. Turn the lid counter-clockwise until it clicks into place.
3. When the lid is correctly installed on the Host the alignment hole on the lid should be pointed
to the LOCK print at the front side of the Host.
4. Attach the rubber feet to the recesses on the lid and put the Host right next to the display.
• Please only use the rubber foot provided with the kit to attach to the Host.
• Please see Positioning the Host antennas on page 16 for guidelines on positioning the antenna to maximize

14 Installation
Installing the Host on the wall or trolley
If you need to install the Host near a display:
1. Stick double-sided tape to the lid of the Host.
2. Affix the Host on the wall near the display.
3. Keep the antennas away from any signal obstructions.
You can also place the Host on a mobile display trolley. See the illustration.
• Please only use double-sided sponge tape on the lid of the Host.
• Please wait 24 hours after you attach the double-sided sponge tape to the lid of the Host.
15 Installation
Positioning the Host antennas
Once you have properly installed the Host, follow the guidelines below to position the antennas to
maximize signal reception:
For ceiling installation
Position the antennas so that they are both pointed downwards at an angle roughly perpendicular to
the ceiling:
For ceiling mount installation
• Position the antennas so that they are both point either upwards or downwards roughly parallel to
the ceiling mount:
• If you encounter bad signal reception after initial use of the Host you can manually adjust the
antennas so that they tilt at a slight angle to maximize signal reception. When doing so, avoid tilting
the antennas toward the ceiling mount:
16 Installation
• Avoid positioning the antennas in a horizontal manner, this may result in a weak signal reception:
• If the Host is attached to a metallic ceiling mount ensure that the antennas are at least 3 cm away
from the metal portion of the ceiling mount:
3 cm
3 cm
For table placement
Position the antennas so that they are both pointed upwards roughly perpendicular to the table:
Connecting the HDMI cable and power
Once the Host has been positioned properly near the display, connect the HDMI cable and power to
ensure signal transmission.
