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 signals, you can reduce the scanner's sensitivity to these signals.

There are two attenuator modes in your scanner. In normal attenuator mode, you set the attenuator in each channel or each band/ group in the search and tune mode. In global mode, you set the attenuator only once. The global setting affects 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, ã appears at the seventh digit in the top line.

When you turn it off, ã changes to "ô". You cannot set the attenuator while the scanner is scanning.

Press FUNC then ATT to set the attenuator to

the global mode.appears for 2 seconds at the bottom line and Wý (on) or # (off) appears. Press ATT to turn on or off the attenuator. ã00FE or ã00Vý appears on the bottom line while scanning.

Press FUNC then ATT again to turn off the global attenuation mode. *FID8Cýã00 is indi- cated at the bottom line for 2 seconds.

Note: If you turn on the attenuator, the scan- ner might not receive weak signals.

TURNING THE KEY TONE ON AND OFF
