The location must have access to a dedicated 110 Volt AC (±10%), 60
Hz, single-phase circuit with a circuit breaker or fuse rated at 15 amps.
A 3-wire parallel blade grounded outlet should be within
approximately 6 feet of the lower left rear of the BKSU mounting.
The location must have access to a good earth ground, such as a
metallic cold water pipe without non-metallic joints. The ground
source should be located as close as possible to the system.
The system should be located in an area that is well ventilated with a
recommended temperature range of 68°-78° F and a relative
humidity range of 5-60% (non condensing).
The system should be located within 25 feet of the telephone
company' s termination point. Also, the location should be within the
prescribed station loop lengths for all keysets and terminals. If
existing cabling is used, its location and conduits should be
considered. Station wiring should be in the building. Station ports are
not designed for installation outside of the building.
Protection from flooding, flammable materials, excessive dust and
vibration.
The site should be away from radio transmitting equipment, arc-
welding devices, copying machines and other electrical equipment
capable of generating electrical interferences.
Operation of this equipment in a residential area is likely to cause
interference. In which case the user, at his own expense, is required to
take any necessary measures to correct the interference.
