Scanner Setup
A frequency, expressed in kHz or MHz, is the tuning location of a
station.
Your scanner saves frequencies to channels and groups the
channels into banks. The scanner’s 10 banks each hold 100
channels (1,000 channels total).
The scanner is preset to the most common AM or FM receive
modes for each frequency range. However, some amateur
transmissions may operate in a different mode. If the transmission
sounds weak or distorted, you may have the channel set to the
wrong receive mode:
AM – Amplitude Modulation, primarily used for aircraft, military,
some amateur and government transmissions.
FM – Frequency Modulation, used for most public safety
transmissions, broadcast, business, and most amateur radio
transmissions.
CT – FM transmissions with Continuous Tone Coded Squelch
System (CTCSS)
DC – FM transmissions with Digital Coded Squelch (DCS)
MO – Motorola Trunking System
ED – EDACS Trunking System
LT – LTR Trunking System
Note: If you change the receive mode using MODE key,
the scanner shows the receive mode for small caps (ex.
fm,
am, ct, or dc
). If you want to change the default setting,
press FUNC then press MODE.
Defining a Channel
Go to www.radioreference.com for the latest frequency references.
To define a channel:
1. Press MAN.
2. Enter the bank (0-9) and channel number (00-99) where you want
to store the frequency (Example: 101 for Bank 1, Channel 1).
3. Press MAN again. “
M”
and the bank and channel number
appear.
4. Press PROG. “
M”
changes to “
P”
.
5. Use the number keys to enter the frequency (including the
decimal point). If you make a mistake, press CLEAR to delete a
single digit or hold CLEAR about 2 seconds to start over.
Note: Your scanner automatically rounds to the nearest
valid frequency. For example, if you enter 151.553, your
scanner rounds to 151.550.
6. If necessary, press MODE to change the receiving mode.
7. Press ENT.
If the frequency is already stored in the bank,
“Dupl.Freq.
ChXXX”
appears. To copy the duplicate frequency anyway,
press ENT or press CLEAR to cancel.
If you made a mistake in Step 5,
“Invalid Freq.”
briefly
appears and the scanner beeps when you press ENT. Go back
to step 5 again.
8. Press MAN again. “
M”
and the bank and channel number
appear.

or bank, see “Text Tags” on Page 47.
