COMTEK BST 25-216 - Manual (Page 7)

To avoid this type of interference, select frequencies from one
of the standard groups (see frequency group charts on page 11), or
use COMTEK’s frequency selection guide software to determine
appropriate frequencies. (Contact COMTEK to obtain a free
copy of the frequency selection software.)
Test Tone
The BST 25-216 base station transmitter has an internal 400 Hz
source which is transmitted when the “TONE” switch is
enabled. This source is intended to be used to make technical
adjustments and to verify the operation of the system. Under
normal operation the “TONE” switch should be disabled.
Speech EQ
On the back of the transmitter there is a switch labeled “EQ”. With
this function enabled (switch up), the audio dynamics and frequency
response are processed to improve intelligibility of speech. If the
primary audio source is going to be speech, you should enable this
processing. If the main audio source is going to include music in-
formation, you should disable it. You may want to experiment to
determine which position sounds most pleasing with the program
source you intend to use.
