key. If the squelch is on during the scan routing, scanning
will pause on a squelch break. If there is no further activity
on that channel, scanning will resume after 5 seconds. The
Tuning Knob can be used to change the direction of the scan
and to step through the scan banks manually.
RATE
The Rate function allows you to select pre-programmed
scanning speeds of both frequencies and channels which
range from .2 seconds to 40 seconds. See Section 13.11,
Changing Frequency or Channel Scan Rates, for specific rates.
8.2 SHIFT Functions
To access the secondary function keys on the upper half on
the front panel, the operator will depress the
SHIFT/FUNC
key prior to pressing the desired key. Secondary functions of
keys (The functions printed above the buttons on the panel)
are described as follows:
Control Head #
This key is used to view the Control Head number pre-
programmed by the manufacturer (see INTCM-XCV key in
preceding section).
View Timer
These two keys are used to preview the pre-programmed
alarm times and their corresponding channel or frequency.
SQL Level
This function allows you to set a squelch level by rotating the
Spinner Knob clockwise or counterclockwise. To optimize
the squelch level, depress the Up and Down buttons
respectively and increase the SQL-Level once or twice. This
function allows for optimum detection and minimum
background noise. For viewing purposes, the adjustment
levels are displayed on the bar coded meter.
RF Noise Blanker
This optional feature allows the radio to recover information
that would otherwise be drowned out by high powered
impulse type noise. In noisy environments, engine spark
noise, lightning, radar pulses or other EMI sources can cause
the radio's built-in automatic gain control to reduce the
sensitivity to the input signal. With the noise blanker,
incoming noise is detected and turns off the receiver for the
length of the noise pulse, thus preventing the automatic gain
