Note: You can use HyperSearch only in the 5 kHz step bands (29–54 MHz and 137–174 MHz).

SKIPPING DATA

SIGNALS

You can set the scanner so it skips nonmodulated or data signals (such as modem transmissions) during a scan or search.

Note: Since data signals are not gen- erally found in the air band, this fea- ture does not work in the air service bank.

To turn on the data skip feature, be sure the priority feature is turned off (see “Priority” on Page 24), then press DATA. DATA appears. To turn off the feature, press DATA again. DATA dis- appears.

TRUNK TRACKING

Your scanner is designed to track transmissions on Motorola Type I, Type II, and hybrid analog trunking systems, which are extensively used in 800 MHz communications. Remem- ber these important points when track- ing transmissions:

Your scanner monitors Type II systems by default. However, you can change this if the system in your area is different (see “Types of Trunking Systems” on this page and “Scanning Type I and Hybrid Trunked Systems” on Page 33 for more information).
