PRO-2004 Programmable Scanner
(200-0119) Operation - Part 1 Faxback Doc. # 31915
Turn on your PRO-2004 by rotating the OFF/VOLUME clockwise. When first
turned on, your PRO-2004 might start scanning. Rotate the SQUELCH fully
counterclockwise. You'll hear a rushing noise from the speaker - if not,
rotate the VOLUME control a little further clockwise - and the scanning
will stop. Slowly rotate the SQUELCH clockwise until the noise stops and
scanning resumes. You are now ready to start entering frequencies.
UNDERSTANDING THE DISPLAY AND KEYBOARD
The liquid crystal display (LCD) on your PRO-2004 displays the channel
number, the frequency being received, status of different functions, DELAY
or LOCK OUT, and current operation mode. As they move on and off the
display, you can note the current operation mode. On the display, the
line under the bank number shows you which bank you are working with. The
numerals below the bank number on the keyboard show you the channel numbers
in each bank. Bank 1 holds channels numbered 1 through 30, bank 2 holds 31
through 60, and so on through bank 10, which holds the channels 271 through
300.
BATTery Indicator
When the memory backup battery power becomes low, the [BATT] indicator
appears on the display and the PRO-2004 gives off a beeping alarm sound.
Replace the battery promptly.
ERROR Indicator
Sometimes when you try to enter a frequency for a channel or as a search
range limit, you will find an ERROR on the display and hear three beeps.
This means the frequency chosen is in error, and you won't be able to enter
it into your PRO-2004.
Such frequency errors usually mean you've attempted to enter a frequency
outside the range of your PRO-2004, such as 550.000 MHz, or you've put a
decimal point in the wrong place; for example, 14.682 MHz instead of 146.82
MHz. Check your entry carefully and then press [CLEAR]. You can now enter
the correct frequency.
The ERROR indicator also appears when you try to enter channel number
outside the limits of the PRO-2004, such as channel 500.
About those Banks...
The PRO-2004 has ten banks for continuous storage, plus an eleventh bank
for temporary storage. Think of it in this way: it's like storing gold in
a bank. You have so much gold that one safety deposit box cannot hold it
all. So, you rent additional safety deposit boxes. When you have filled
all the boxes in one bank, you put the excess into another bank.
Now, suppose you are still searching for additional gold. If you are
undecided about the disposition of a gold strike, whether to store it or to
spend it, you can place it in a special services bank for temporary
storage.
Permanent-Memory Storage Bank
Your PRO-2004 has a comparable storage system for radio frequencies. It
has 10 banks and each bank has 30 storage compartments (like safety deposit
boxes) which are called channels. Into each bank, you can safely deposit
as many as 30 frequencies. Because there are 10 banks with 30 channels
each, you can ultimately store a total of 300 frequencies. The smaller
numbers on the keyboard indicate which channels are allocated to each bank.
When the frequencies have been stored, you can scan the banks to find a
specific channel.
Temporary-Memory Storage Bank
In the search mode, when you discover a new frequency, you can place it in
the temporary storage bank. Think of this eleventh bank, special services
bank, as the MONITOR bank. It not only helps you, in a rapid search, store
new frequencies, it also performs rapid transfer to any of the other ten
banks. On the display, MONITOR indicates that you are using this bank.
When in the monitor mode, the ten numbers at the top of the display
represent ten channels in which newly-discovered frequencies may be stored
temporarily.
NOTE: Monitoring can only be accomplished in conjunction with "search".
See "Storing Frequencies with Monitor Channels".
The blinking number is the MONITOR channel in use.
SEARCH BANK
The PRO-2004 has 10 search banks for setting the lower limit or upper
limit of the search range. The display shows the search bank numbers.
OPERATING MODES
The PRO-2004 has four separate operating modes: programming - manual -
scanning - searching operation
PROGRAMMING FREQUENCIES
Programming the PRO-2004 is as simple as 1-2-3 as follows:
1. Select the desired channel.
2. Press [PROGRAM] to enter the programming mode.
3. Enter the desired frequency with the keypad and press [ENTER].
NOTE: If you are uncertain about specific frequencies in your local area,
Radio Shack's "Police Call Directory Including Fire & Emergency
Services" is an excellent reference.
Example: To program 162.55 MHz into channel 30
Select the channel in one of three ways:
STEP 1.
a. Press [MANUAL]. Continue pressing until the display shows channel
30. Release the button.
- or -
b. Press [3] [0] [MANUAL]. In either case, press [PROGRAM] to enter
the programming mode:
- or -
c. Press [PROGRAM].
Press [3] [0]
Press [PROGRAM].
STEP 2.
Press the keys 1 6 2 . 5 5
STEP 3.
Press [ENTER]
To program the next frequency, move to another channel in this way. Press
[PROGRAM] to advance to the next channel.
Repeat the same steps to add more frequencies.
Hints and Tips for Programming
If you make a mistake while entering a number, press [CLEAR] and re-enter
the correct frequency. If you enter a frequency that is outside a PRO-2004
band range, the ERROR indicator lights along with a beeping sound. Press
[CLEAR] and select another frequency. Any frequency within a PRO-2004 band
range will be accepted. However, the frequencies that can be stored into
PRO-2004 memory are in either 5 kHz steps or 12.5 kHz steps. The scanner
will automatically round off the entered frequency to the closest valid
frequency. For example, if you enter 125.2345 MHz, the PRO-2004 will
accept this entry as 125.2300 MHz. The entry 398.2640 MHz will be treated
as 398.2625 MHz. The tuning range of your PRO-2004 is permanently stored
in the microprocessor chip and external memory. It cannot be extended or
altered. So if you try to enter a frequency not in the PRO-2004 tuning
range, you'll always get an error message. If you want to change the
frequency entered for a specific channel, enter the new frequency over the
old one, following the steps under Programming Frequencies.
MANUAL MODE
When you want to stay on a frequency, either in scan mode or search mode,
press [MANUAL]. In the manual mode, you can manually advance through the
memory channels by pressing [MANUAL] repeatedly. Or enter the channel
number and press [MANUAL] to reach the desired channel directly. Also note
that in manual mode you can access locked out channel(s) or skipped
bank(s).
SCANNING FREQUENCIES
Your PRO-2004 will automatically scan all the channels you have programmed
and stop whenever it finds a signal.
Important! Your PRO-2004 won't scan unless SQUELCH is set to the point
where no "hiss" sound is heard between transmissions.
To stop scanning, press [MANUAL]. You then can select a specific channel
you want to listen to. Enter the channel number, then press [MANUAL]. Or
press [MANUAL] and continue pressing until you reach the frequency you
want.
DELAY
In the scanning mode, your PRO-2004 will stop when it finds a channel with
a signal. As soon as signal stops, it immediately begins scanning other
channels. Since most transmissions are part of a two-way communication,
you may wish to press [DELAY] when you wish to continue listening to a
specific channel.
Press [DELAY] when you wish to hold a channel you are listening to.
Your PRO-2004 will then hold the channel at least two seconds after each
transmission, giving you time to listen to both sides.
DELAY appears on the LCD to show that the delay function is engaged for
that channel. To cancel the delay function, press [DELAY] again. The
display indicator disappears.
FORCED SCAN
Scan stops when a signal is picked up on a frequency. However, if you
wish to re-initiate scanning, press [SCAN] to forcibly begin scanning.
SPEED SELECTION
When the power switch is turned on, the scanning rate is set to 16
channels/second. Pressing [SPEED] alternates the scan speed between 8
channels/second and 16 channels/second.
Locking Out Frequencies (Skipping Frequencies)
You might want your PRO-2004 to skip certain frequencies while it's
scanning (such as continuously transmitted weather broadcasts). To lock
out such channels:
1. Press [MANUAL] to stop scanning.
2. Continue pressing [MANUAL] until you reach the channel you want to lock
out. If you know the channel number(s), this can be done more quickly.
Enter the channel number, then press [MANUAL].
3. Press [LOCK-OUT]. The indicator appears on the display, indicating
this channel will be skipped during scanning.
NOTE: In manual scanning, you can continue to access the locked-out
channel(s).
To cancel the lockout function:
1. Press [MANUAL] to stop scanning.
2. Advance to the channel that is locked out.
3. Press [LOCK-OUT] again. LOCK-OUT disappears from the display.
4. Or, press [LOCK-OUT REVIEW] in MANUAL or PROGRAM mode to call out
locked-out channels one by one. Then, press [LOCK-OUT] to cancel
LOCK-OUT for that channel.
You can lock out as many channels as you like. But each bank must have
at least one channel not locked out. The last channel in a bank cannot
be locked out.
SKIPPING BANKS
At initial 'power-on', all the banks are available to be scanned. You can
skip one entire bank while scanning. This is convenient when there are no
frequencies entered in the bank, so there is no need to scan through it.
Do not use the LOCKOUT key to skip banks. Instead, follow this procedure:
Turn power on, and in the SCAN mode, press the number key that corresponds
to the bank to be skipped.
Example: To skip banks 4, 5, 9 and 10
Press 4 5 9 0
Note that you enter '0' for bank 10.
The corresponding bank number indicator disappears from the display
and the entire bank is skipped.
Press the number key again to restore the bank.
Example: To restore scanning banks 4 and 5
Press 4 5.
Each number on the keyboard has figures; these figures show the channel
numbers that are allocated to that particular bank. As with the lockout
function, you cannot skip all the banks. The 'last' bank cannot be
skipped.
PRIORITY
You can scan other channels and still not miss a transmission of special
interest to you (police, fire, ambulance, etc.). If a call is received on
the priority channel while you are scanning other channels, your PRO-2004
will automatically switch to the priority channel.
Programming the Priority Channel
At initial 'power on', Channel 1 is automatically designated as the
priority channel. So if you enter a frequency of particular interest in
channel 1, you need not do anything further. But, if you want to use
another channel as the priority channel, press [PROGRAM], enter the channel
number and press [PRI]. Only one channel can be set as the priority
channel. If you enter a new priority channel, the previous channel chosen
is automatically cleared.
Example: To set channel 20 as priority
Press [PROGRAM].
Press [PRI].
You can verify the priority channel by pressing [PROGRAM] then [PRI]. The
P on the display will light when you scan the priority channel. Press
[PRI] again to revert to previous channel.
Using Priority
The priority function is available only in scan or manual mode. Press
[PRI] to activate it. PRIORITY appears on the display.
The receiver will check the priority channel and switch to it if a signal
is present.
To cancel priority, press [PRI] again. PRIORITY disappears from the
display.
NOTE: All the settings of delay/lockout/speed/priority mode/step/skipping
banks are retained even when you turn power off. The next time you
turn the power on, the same settings, as when you turned the
PRO-2004 off, are in effect.
