Check your local government ordinance
before sales or operating this product.
Installation:
* This device should be mounted at least 180 cm above the ground
and as close as possible to building's outer side walls and near
windows where the base station signal strength is the highest.
* Installer can use a smart phone to determine measure signal strength.
Signal strength usually can be read in the status page.
* Use a 4mm concrete drill bit to drill two holes 21.5 cm apart and
about 2.5 mm deep. Plug two plastic wall anchors. Drive screw into
the wall. Leave about 2 mm space between screw head and wall surface.
* Hang device securely to these twp screws, adjust screw
head to wall surface to achieve a good grip.
* Plug electric cord to AC receptacle. Red LED at panel center will be on
immediately indicating device is in standby mode.
* Use Infrared Remote Control to power on and off device.
* In case device is to be flush mounted directly on a power recess, original
AC cord needs to be removed first. This can be done by inserting and
press down a 2mm wide flat screw driver into the slot of the connector
next to the wire, while pulling out the wire.
* Gauge 16 to 18 wire can be easily inserted and clutched.
* If remote AC wall switch is used for power on-off control instead of
Infrared controller, first time after the installation, turn on AC switch
and use the infrared controller to power up the unit (red LED becomes
green). Then the power on/off is controlled by the remote AC switch.
A very High efficiency (Ultra low
power consumption) and audio noise
free device. Requires no AC adapter.
Will not interfere with DECT phones.
This is our standard model. More
then 2000 units sold worldwide in

Operation:
* It is a wall mount device for continuous operation
with AC input.
* This product required only 2 to 3 second to power-up
and can immediately blocking down link reception.
* Maximum power radiation plane is perpendicular to device housing.
The radiation power to the front direction is about 4dB
greater then to the back. This radiation plane should be positioned
properly to maximize the cell phone interception during installation.
* To avoid from spilling to unwanted area, the radiation power is optimized
for most practical applications.
It is not designed with intention to compete in range.
* For large space application, multiple units in cellular formation
should be used.
* This device depends on cooling fins to radiate heat. Proper ventilation
spacing should be provided during installation.
