5. Starting Up
The power supply is turned on via the power switch on the front side of the compact SIR 800
transmitter.
When you use the compact transmitter the first time it is necessary to adjust the provided
channels. This procedure will allocate the transmitter frequencies to the respective channels.
For adjusting this allocation refer to the following figure. The scheme is enclosed with the Compact
Transmitter as a separate sticker which may be adhering to the front panel.
The following allocation is shown on the figure above:
First figure: Channel 1; second figure: Channel 16; third figure: Channel 32
The left DIP-switch 1 will activate the corresponding channel. DIP-switch to ON means channel is active.
DIP-switch has no function.
Do not select the “IF” transmission channel.
5.1 Tuning input/output levels
Before starting a conference situation you should check the sound level in- and output to
avoid level change between floor sound and interpreter sound. This is done by feed in a
test signal to socket “OR-IN” and listening to the corresponding sound level.
Other controls are not necessary for a successful event.
Unused audio channels of the SIR 800 should be turned off to increase the infrared power of the
SIR 801 radiator for the actual number of channels in use.
