Adjustments
There are a number of adjustable potentiometers (pots) on the back panel of the Model
26. Some of these pots must be adjusted before the Model 26 can transmit and receive
properly. The order in which the adjustments are made is important. Each pot will be
described below in the order that it should be adjusted in a new installation. First, there
are a few other details that pertain to making these adjustments.
Both the Model 6 and the Model 26 can produce continuous FFSK test tones, for 30
seconds. These test tones can be used to help in the adjustment of the pots associated with
receiving and transmitting FFSK signals. To activate the test tones, select FFSK Level
Set in the Main Menu of the Software Configuration Program.
Most of the adjustments in this section deal with transmit and receive levels, which only
affect the master Model 26, in a multiple position system. However, it is recommended
that both master and slave units are all configured and adjusted the same. The multiple-
position system must have the audio sources connected in parallel and have one of the
interconnection configurations shown in Appendix C.
When making the receive adjustments, the Model 26 being adjusted must have the
address of the primary unit (address 1). Be sure to re-address all secondary units when
