4 CONTROLS AND INDICATORS

This section defines each control of the transceiver. See Figure 3 for
location of controls. For detailed operating instructions refer to chapter
5 of this manual.

4.1 CONTROLS AND CONNECTIONS

POWER SWITCH/VOLUME CONTROL
Turns the transceiver on and off as well as adjusts the audio volume.
Turn this control clockwise to turn the radio on and to increase the vol-
ume.
Turn fully counterclockwise to turn the radio off.
Secondary Use
When the transceiver is turned on while the SCAN 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.
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.
KEYPAD
16/9 Key
Immediately recalls channel 16 from any channel location. Holding down
this key recalls channel 9. Pressing the 16/9 key again reverts to the
previous selected working channel.
Secondary use
Please see secondary use for the WX key.
