4.3 Radio Options
Hereby, HM Electronics, Inc., declares that SYS6700 is in compliance with the essential
requirements and other relevant provisions of the Radio Equipment Directive (RED). In AFH
mode, SYS6700 complies with European Telecommunications Standards Institute (ETSI)
harmonized European standard EN 300 328. Customers, Distributors or Installers operating
in a CE regulated country that switch off or disable AFH will render the product non-compliant
with the directive and will be considered the manufacturer of the product.
CE Base Station Adaptive Frequency Hopping
Background
The HME SYS6700 wireless system utilizes a Frequency Hopping Spread Spectrum (FHSS)
radio in order to provide robust communications. This system operates in the unlicensed 2.4
GHz band. With the proliferation of other devices over the past few years in the same 2.4 GHz
band, instances where these devices and systems can interfere with each other has greatly
increased.
The European Union has updated the radio standards for equipment operating in this band
in an attempt to reduce interference between equipment from different manufacturers. This
European Telecommunications Standards Institute (ETSI) harmonized European standard is
known as EN 300 328.
Radio Frequency Interference caused by Wi-Fi routers and Access Points
Most Wi-Fi access points allow the administrator to set the channel and bandwidth for
the system. Some systems employ an ‘Auto’ mode, in which the Wi-Fi access point will
automatically select the channel.
With Wi-Fi access points, it is sometimes advantageous to manually select a channel number
to keep the Wi-Fi transmission at a fixed location. Common Wi-Fi channels used are 1 and 11.
In order to avoid the Radio Frequency interference caused by Wi-Fi routers and Wi-Fi access
points, the Base Station offers three user selectable Hop Bands of radio operation. Making use
of these bands can assure that base communication is always free of interference.
Interference may be occurring if
: you’re hearing clicks and/or pops; voices break up while
talking; you’re hearing a “Busy” prompt in headset when a button is pressed; the headset is
flashing red lights; you’re intermittently hearing “Lane 1” in the headset. To adjust this setting,
refer to instructions in Section 4.3.1, next page.
The
Radio Options
allow adjustments to avoid radio frequency interference that may occur
when multiple base stations are installed in close proximity to one another.
