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)

Notes

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
