Telonics TSUR-400, Operation And Programming Manual

Page: 15 / 24

When this screen is displayed, pressing the UP/DN keys changes the
selection between 0 and 9. (Holding down either key will allow the
numbers to increment or decrement at an increasing rate.) Changing the
numbers in the direction of 0 “tightens” the squelch while changing in the
direction of 9 “opens” the squelch. Proper adjustment is accomplished by
tightening the squelch until “noise” is heard, then slowly backing off until
the “noise” stops and must be accomplished with the audio enabled. This adjustment will have to be
performed any time there is a change in background noise being received. When the desired setting is
accomplished, pressing the FN key programs the receiver and the screen reverts back to the Setup
Menu Level 2 display screen.
