Beyond the Basics
CT – accesses the FM mode, CTCSS System
DC – accesses the FM mode, DCS System
MO – accesses the FM Mode, Motorola Trunking System
(with 4- or 5-digit ID code)
ED – accesses the FM Mode, EDACS Trunking System (with
4-digit decimal ID code or 5-digit AFS code)
LT – accesses the FM mode, LTR Trunking System (with 6-
digit ID code)
MO (MOT), ED, and LT 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 signals, you
can reduce the scanner’s 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 ATT to turn on or off the attenuator while the channel
number is indicated or while the scanner is searching through
bands/groups. When the attenuator is on, att changes to ATT.
When you turn it off, ATT changes to att. You cannot set the
attenuator while the scanner is scanning.
Press FUNC and then ATT to set the attenuator to its global
mode. Global ATT. appears for 2 seconds at the bottom line and
atg appears. Press ATT to turn the attenuator on or off. ATG or
atg appears on the second line.
Press FUNC and then ATT again to turn off the global attenuation
