Before You Begin
The transmitter can be set up using the two push buttons and the mode switch on the
transmitter.
transmitter.
Setting Up
The transmitter must be adjusted in order to ensure an optimal function. The
adjustment of the mode takes place by means of the Mode Switch on the transmitter.
The adjustment of the RF input level and the pilot tone level takes place by means of
the keys (+) and (-) on the transmitter. A short press on the key will change the level
in small steps. If the key is pressed constantly, the level will change in major steps.
Five seconds after releasing the key the actual set-up will automatically be stored in
the memory.
Note: The set-up of the transmitter will also be saved even though the supply voltage
disappears.
Note: The parameters can also be set by the handheld A91200 and LCI tool. Refer to
the manual of the node for further instruction.

To set up the RF input level
The keys (+) or (-) can change the input level by 0-10 dB in steps of 0.1 dB. If the key
is pressed constantly, the level will change in major steps. The RF input level at the
transmitter can be measured at the test point to the reverse path - named TP-R on the
node.
The RF level in the transmitter must be adjusted according to the number of channels
(carriers) that have to be transferred. This RF level together with the incoming signal
to the reverse receiver determines the output level at the receiver. The coherence
between these values is shown in the table at below.
