Operating Your Pro-2020
Turn on your Pro-2020 by rotating [VOLUME] clockwise.
on, your Pro-2020 may start scanning).
(When first turned
Rotate [SQUELCH] fully counterclockwise. You'll hear a rushing noise from
the speaker. Slowly rotate [SQUELCH] clockwise until the noise just stops.
You're now ready to start entering frequencies.
Programming Frequencies
Before programming frequencies, make sure your Pro-2020 is turned on and
the SQUELCH is adjusted.
Suppose you want to program Channel 1 to receive 162.55 MHz.
you would do it:
Here's how
1.
Press [MANUAL] and select channel 1. You can do this in two ways:
press [MANUAL] continu ously until the Display indicates Channel 1 or
by pressing [1] [MANUAL].
2.
Press [PROGRAM] to enter the programming mode.
3.
Enter the desired frequency. In this case, press the [1] [6] [2] [.]
[5] [5] keys. Check the display to make sure th e frequency it shows
is the one you meant to program. If it is, press the [ENTER] key.
4.
To add more frequencies, just press [PROGRAM] to advance to the next
channel and follow the steps above.
5.
If you ever want to change the frequency entered for a specific
channel, just enter the new frequency "over" the old frequency using
steps 1, 2, and 3.
Make a mistake while entering the frequency? Just press [CLEAR], enter the
correct frequency and press [ENTER]. If you're entering a new frequency in
place of an old one, the old frequency won't be "erased" when you press
[CLEAR]. It will remain stored on that channel until you correctly enter a
new frequency and press [ENTER].
You'll hear a "peep" sound as you press the various keys. This lets you
know the key has been properly "entered" into your Pro -2020.
Using the Scanning Function
Your Pro-2020 will automatically scan all the channels you've programmed
and stop whenever it finds a signal. To scan channels, just press the
[SCAN] key.
To stop scanning, just press [MANUAL] and you can select specific channels
you want to listen to.
IMPORTANT!
Your Pro-2020 won't scan unless SQUELCH is set to the point
where no sound is heard i f a signal isn't being received.
Delay Function
When your Pro-2020 is scanning, it will stop whenever it finds a signal on
a channel. As soon as the signal ends, the scanning function will resume.
Most communications heard will be two -way. To make sure you don't miss any
replies, press [DELAY]. This will cause your Pro -2020 to stay on a channel
for two seconds after the end of a transmission, giving you time to hear
any reply. To release the Delay function, just press [DELAY] again.
The
Delay indicator will show on the display when the Delay function is used.
Lockout Function
You may want your Pro -2020 to "skip over" certain frequencies while it's
scanning (such as continuously transmitted weather broadcasts).
To "lock
out" such channels, follow these steps:
1.
Press [MANUAL] to stop scanning. Continue to press [MANUAL] to
advance to the channel you want to lock out.
2.
When you reach the channel, press [LOCK OUT]. The display will show
[o] to indicate this channel will be skipped over during scanning.
3.
To release the lockout, press [MANUAL] to stop scanning. Advance to
the channel that is locked out and press [LOCK OUT] once again.
[o]
will disappear from the display.
If you use the lockout function on all ch annels, scanning will be
impossible - you'll only be able to change channels using [MANUAL].
Speed Selection
Your Pro-2020 will normally scan channels at a rate of four channels per
second. If you press [SPEED], channels will be scanned at a rate of nine
per second. Press [SPEED] again to return to a rate of four channels per
second.
Priority Function
You might want to scan other channels yet not miss a call on a channel of
particular interest to you (police, fire, ambulance, etc.). The Priority
function will let you scan other channels - but if a call is received on
the Priority channel, your Pro -2020 will automatically switch to the
Priority channel!
1.
Only Channel 1 can be used as Pr iority Channel: Key in the desired
Priority frequency into Channel 1.
2.
Priority function works only when the unit is in Scan or Manual mode.
3.
Press [PRIORITY] to start Priority function.
display.
4.
Press [MANUAL] or [SCAN] to listen to other channels. Your Pro-2020
will check the Priority channel and switch to it if a signal is
received on it.
5.
To cancel Priority function, press [PRIORITY] again.

A [P] will appear on the
the [P] will
SEARCHING WITH YOUR PRO -2020
One great feature of your Pro -2020 is its ability to "search" for
frequencies being used. This means you can hear all the action on the
airwaves in your area! To use this great feature, just follow these steps:
1.
Press [PROGRAM] key.
2.
Press [LIMIT] key. Enter the lower limit of frequency range to be
searched (such as 45.00 MHz). Press [ENTER].
3.
Press [LIMIT] key again. Enter the upper limit of frequency range to
be searched (such as 46.00 MHz). Press [ENTER].
4.
Press either [up arrow] or [down arrow] to start Search. [Down arrow]
will start search from the highest frequency and go down. [Up arrow]
will start from the lowest frequency and go up.
5.
You can control the speed of the search by using the [SPEED] key to
accelerate or to slow down the search.
6.
Search will stop when a frequency is found with a signal.
search, press [up arrow] or [down arrow].
To restart
In Program Mode, search range will be displayed each time [LIMIT] is
pressed. It is impossible to change the lower frequency only: to change
lower frequency you must change higher frequency first. The higher
frequency can be changed any time.
Storing Frequencies
If you want to enter some of the frequencies found during search, do this:
1.
Press [MONITOR] when your Pro -2020 finds a frequency you want to store.

the old frequency.
6.
Press either [up arrow] or [down arrow] to resume the search.

but don't worry - the old frequency will be erased when

Error Indications
Sometimes when you try to enter a frequency for a channel or as a search
range limit, you may find an ------ on the display. This means the
frequency is in error and you won't be able to enter it into your Pro -2020.
Such frequency errors usually mean you've entered a frequency outside the
ranges your Pro-20202 operates on (such as 225.00 MHz) or you've put the
decimal point in the wrong place (14.682 MHz instead of 146.82 MHz).
Check
carefully to find your mistake and then press [CLEAR]. You can now enter
the correct frequency.
