SETTING UP PROCEDURE

When all connections are made you can dial the caller to whom you want to talk.

If this connection is made you connect the caller to the mixing console by pushing the HOOK

switch. Now listen by means of a PFL (CUE) switch on your mixer to the caller and adjust while

talking the Side tone trimmer so that the outgoing signal (your voice) is best attenuated.

Note: the line balancing to your own telephone station has to be performed one time only,

when no changes are made to the telephone system in your place.

The maximum attenuation will be between 20 to 26 dB.

Note: This also depends upon the characteristics of the telephone line system on location.

Hook

The function of the "HOOK" switch is to connect the hybrid to the telephone line instead of the

phone itself (which can be switched off depending upon the jumper J7/8 setting inside the

TelCom unit).

Default factory setting is that the Phone is not switched off.

The green led indicates that a connection has been made.
