The STS-F70 Staff Unit is a self standing module for the Staff Side. It should be placed conveniently on
the counter top so the cashier can hear the loudspeaker and talk into the gooseneck microphone to
the customer. The microphone is of the close talking type so background noise is not picked up. A
‘Mute’ switch is located on the front of the Staff Unit. In the absence of a cable port, a suitably sized
hole should be drilled into the counter top at the rear of the Staff Unit to take the reinforced cable.
Disconnect the 2 two-way plugs before introducing the cables for a neater installation. Ensure these
are re-connected correctly or the system will not operate.

Each component (Microphone, Loudspeaker, Staff Unit or Induction Loop) comes fitted with two-way
connection plug(s) which locate into the appropriate socket(s) at the rear of the Amplifier. The plugs
connect to the cables by screw terminal connections so cables can be removed and fed through small,
neat apertures for an unobtrusive, discrete installation. However, the cables and plugs must be re-con-
nected correctly or the system will not operate. If in
doubt, mark the wires before disconnecting the plug(s). If
there is a suitable cable port on the cashiers side, the
Staff Unit cables can be diverted through this without the
need to remove and re-connect the 2 two-way plugs.
Controls are provided on the front of the Amplifier. The
latching push switch marked ‘power’ switches the unit
on or off, a red LED indicates when the unit is on. Two
rotary volume controls marked ‘customer’ and ‘staff’
adjust output from the loudspeakers. The volume of the
system may be adjusted by turning the rotary volume
controls clockwise (to increase the level of sound) or
anticlockwise (to decrease the level of sound).
