4 CONTROLS AND INDICATORS
NOTE
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. To
turn the transceiver on press and hold this knob until the LCD turns on.
To turn it off, press and hold this knob until the LCD turns off. When the
power is turned on, the transceiver is set to the last selected channel.
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, and priority
scan assignments. 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.
CHANNEL SELECTOR KNOB
Rotary knob used to select channels and, to choose the item selection of
different functions (such as the DSC operation). The [
UP
(
p
)] / [
DOWN
(
q
)]
key on the microphone can also be used to select them.
Secondary Use
While holding down the [ SCAN
] Key and turning the
CHANNEL selector
knob, you can confirm memory channels for scanning.
