1. Charge batteries now
The rechargeable batteries inside your transmitter require charging before use. In order
to be able to test the system once it is installed, we recommend you start charging the
transmitter before carrying on with the installation.
Even an hour or so will give enough charge to test the system ‒ 1 hour charge gives
40mins use.

2. Fitting the speakers
Four wall- mounted speakers are installed and a wire is run
from each of the speakers to one of the 4 SPEAKER terminals
pairs on the back of the receiver.
Please do not think home hi-fi and put the speakers in
the corners, at waist level and point them to the centre
of the room ‒ this is the worst possible thing to do!
Placing loudspeakers for a classroom soundfield is more
like deciding how best to light a room using 4 small
lamps. If you think ‘light’ you will not go far wrong, i.e.
fitted above head height (2 to 2.5 metre high) each over
a 1/4 of the room pointing down on the area to be
covered.
The positioning of speakers is often dictated by physical
objects such as windows. You have to fit 4 speakers so
adapt your ‘lighting’ plan to give the best pattern for the
students ‒ perhaps avoiding the window, an unused end
of a classroom or a teachers desk.
