5 CONTROLS AND INDICATORS

This section defines each control of the transceiver. See Figure 4 for

and
[
WX
]
keys are held down, the internal microprocessor is reset. This clears the
memory and all user-programmed settings, such as scan memory. This
condition is known as the default condition, the same as when shipped
from the factory. For a list of these defaults, see the section on Resetting
the Transceiver’s Microprocessor.
NOTE
Resetting the microprocessor will not erase DSC MMSI and Direc-
tory Call information.
SQUELCH CONTROL (SQL)
Sets the point at which random noise on the channel does not activate
the audio circuits but a received signal does. This point is called the
squelch threshold. Further adjustment of the squelch control will degrade
reception of wanted transmissions.
