b. On the receiver, press and hold the SET button until DISPLY shows in the display.
c. On the receiver, press two times to display SQELCH.

10dB) will flash.
e. On the receiver, press to decrease the squelch setting or to increase it.
f. On the receiver, press SET to enter the new setting and return to the main screen.
g. T urn on the transmitter and walk test the unit. Maximum squelch (50dB) maximizes noise immu-
nity but limits the range. Minimum squelch (5dB) will maximize the range but allow more noise
to break through the squelch. Never leave the squelch set to 0dB except for testing, white
noise will be constantly present on the audio outputs.
h. Repeat to fine tune receiver squelch to the desired setting.
