Squelch and Attenuator
The squelch and attenuator control the scanner sensitivity. If squelch
is set too high, the scanner may scan slowly or stop on noise or
silence. If this happens, adjust squelch using the steps above, or for
conventional channels, set the correct subaudible squelch mode.
See “Appendix B: Detailed Menu Reference: Conv Menu” on page 101.
With the attenuator on, the scanner might not receive weak signals,
but immunity to adjacent strong signals is improved.
You can reduce interference using two attenuator modes:
• Global – The attenuator setting is applied to all channels, bands, or
groups.
• Normal – Lets you set the attenuator in each channel, band, or group.
Note: You cannot set the attenuator while scanning.
To set the attenuator mode in the Global Menu:
1. Press PROG for Program Mode.
2. Press GLOB softkey to access GLOB menu.
3. Press p or q to scroll to Atten Mode.
4. Press t or u to select Global or Normal.
5. When attenuator is set to Global, you can set Global attenuator
on or off. Press p or q to scroll to Global Atten.
6. Press t or u to select on or off.
7. Press SAVE softkey to save the new setting.
To set the attenuator mode using the ATT key:
When the scanner is in Manual Mode, Program Mode, Search Mode,
Signal Stalker Mode, or when the scan stops:
• Press ATT to toggle on and off the attenuator setting.
• Press FUNC ATT to toggle on and off the global attenuator setting.
Basic Settings
The Global menu stores all of the radio-wide settings used by the
scanner. The Global menu allows you to “tweak” these settings to
your liking. The default settings will work fine for most users, but you
may want to use the Global menu to personalize the radio to suit
your individual tastes. The most common settings are described in
the following sections. Refer to “Appendix B: Detailed Menu Reference:
GLOB Menu” on page 96 for a description of all the settings.
• The active parameter is always the middle parameter and is
indicated by a flashing colon (:).
• Some Global parameter changes do not take effect until the
Global menu is saved.
• Help is available for every menu parameter. Press FUNC SEL to
view help for the selected parameter. Press SEL to exit help.
• The Undo softkey appears in fields where numerical values can
be set, allowing you to exit a parameter field without saving
changes. A note will appear: “Unsaved Changes! Go Back?”
Press YES to go back to the field and continue editing. Press NO
to discard changes and return to the previous menu.
• Each menu parameter features a Dflt softkey that can be used
to restore the value to the factory defaults. This can be very
useful if you make a change to a parameter but do not like the
result.
• You can restore all Global settings to their defaults without
affecting your programmed objects or V-Scanners. Power cycle
the radio, then press 0, then 2 during the welcome message
display. Press ENT to confirm the Global parameter reset.
