!— accesses the FM Mode, EDACS Trunking System (with 4-digit decimal ID code or 5-digit AFS code)

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 sig- nals, 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 chan- nel number is indicated or while the scanner is searching through bands/groups. When the attenuator is on, ã ap- pears 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. #CF98Cýã00ô appears for 2 seconds at the bottom line and W or # appears. W means the attenuator is on and

#means off. Press ATT to turn on or off the attenuator. ã00FE or ã00Vý appears on the bottom line while scan- ning.

Press FUNC then ATT again to turn off the global attenu- ation mode. *FID8Cýã00 is indicated at the bottom line for 2 seconds.

Note: If you turn on the attenuator, the scanner might not receive weak signals.
