							41Operation
The scanner scans through all channels (except those
you have locked out) in the active banks (see Turning
Channel-Storage Banks Off and On and “Locking Out
Channels or Frequencies” on Page 42).

Turning Channel-Storage Banks Off and 
On
To turn off banks while scanning, press the banks num-
ber key so the banks number disappears. For example,
to turn off bank 1, press 
1. The scanner does not scan
any of the channels within the banks you turned off.
Notes:
• You cannot turn off all banks. There must be at least
one active bank.
• You can manually select any channel in a bank,
even if the bank is turned off.
To turn on banks while scanning, press the number key
until the banks number appears. For example to turn
bank 1 on again, press 
1.
Deleting Frequencies from Channels
1. Press MANUAL.
2. Use the number keys to enter the channel with the
frequency you want to delete.

USING THE DELAY FUNCTION
Note:
 Delay is automatically set as the default for each
channel when you turn on the scanner.
Many conversations might have a pause of several sec-
onds between a query and a reply. To avoid missing a
reply, you can program a 2-second delay into any of
your scanners channels. Then, when the scanner stops
on the channel, 
 
     appears and the scanner continues to
monitor the channel for 2 seconds after the transmission
stops before it resumes scanning or searching.
To turn delay on or off, press 
. /DELAY.
LOCKING OUT CHANNELS OR 
FREQUENCIES
You can scan existing channels or search frequencies
faster by locking out channels or frequencies that have a
continuous transmission, such as a weather channel.
Locking Out Channels
To lock out a channel while scanning, press L/OUT when
the scanner stops on the channel. To lock out a channel
manually, select the channel then press

Reviewing the Lock-Out Channels
To review all locked out channels, press MANUAL, then
repeatedly alternate between pressing 
FUNC then L/OUT
to view each locked-out channel. When you finish re-
viewing locked-out channels, press 
MANUAL.
Locking Out Frequencies
To lock out a frequency during a search, press L/OUT
when the scanner stops on that frequency. The scanner
locks out the frequency, then continues searching.
Notes:
• The scanner does not store locked out frequencies
during a search.
• You can lock out as many as 50 frequencies in each
bank. If you try to lock out more,

teresting transmission on a specific channel. When
priority is turned on, the scanner checks that channel ev-
ery 2 seconds, and stays on the channel if there is activ-
ity until the activity stops.
Notes:
• The priority feature does not operate while the scan-
ner receives trunking (voice channel) frequencies.
• If you program a weather channel as the priority
channel, the scanner stays in the priority channel
only when the scanner detects the weather alert
tone.
To program a frequency in the priority channel:
1. Press 
MANUAL.
2. Use the number keys to enter the channel number
which contains the frequency you want to program
as the priority channel. Then press 
MANUAL again.

Note:
 MO (MOT) and ED modes are not available when
the scanner tunes up or down through the frequency
ranges in which the trunking operation is not used.
USING THE ATTENUATOR
To reduce interference or noise caused by strong sig-
nals, you can reduce the scanners sensitivity to these
signals. 
There are two attenuator modes in your scanner. One is
normal attenuator mode in which you set the attenuator
in each channel or each band/group in the search and
tune mode. The other is global mode in which you set
the attenuator only once. This setting is applied all the
time in every mode.
Press 
AT T to turn on or off the attenuator while the chan-
nel number is indicated or while the scanner is searching
through bands/groups. When the attenuator is on,

Trunking Operation
The scanner sends the data. To exit the clone mode, re-
move the cable.
ˆTrunking Operation
The scanner tracks transmissions that use the Motorola
Type I and Type II (such as Smartnet and Privacy Plus)
and hybrid analog trunking systems, plus GE/Ericsson
(EDACS) type systems extensively used in many com-
munication systems.
Trunking systems allocate a few frequencies to many dif-
ferent users. When the mobile unit transmits a signal,
one frequency is chosen from among the allocated fre-
quencies in that trunking system. The users ID talk
group is sent with the signal.
To receive trunking signals, you must store all the trunk-
ing 
control frequencies for Motorola systems or all the
trunking 
group frequencies for EDACS in one bank (see
“Storing Known Frequencies into Channels” on Page 25)
and input ID codes in the ID memory (see “Storing Talk
Group IDs” on Page 58). 
Your PRO-93 automatically calculates Motorola voice
channel frequencies when it decodes the control chan-
nel. This eliminates the need to enter all the Motorola
group frequencies. 
The control channels are subject to change depending
on the day. Therefore enter all the control frequencies in
the same bank. If you do not know which is the control
channel, it is better to enter all the system frequencies
into the same bank. (Refer to the supplied 
Trunking
Guide
.)
When the scanner decodes the Motorola control channel
and finds the voice channel, the scanner displays the
control channel memory location on the top line, the re-
ceived frequency with VC (voice channel) on the second
line, the bank and control channel memory location num-
ber on the third line and the Motorola ID number on the
bottom line.
