To switch between normal and HyperSearch speeds, during a limit search, press SPEED/PRI. SRCH flashes dur- ing hypersearch.

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

BATTERY SAVE

To save battery power when a channel is manually se- lected, the scanner’s battery save function automatically sets the scanner to a standby mode if the scanner does not receive any signals for more than 1 minute. During the standby mode, the scanner repeatedly turns off the internal power for 1 second then turns on the internal power for about 1/3 of a second to check for a transmis- sion.

Note: The scanner’s battery save function does not work if the priority function is on, even if a channel is manually selected.

SKIPPING DATA SIGNALS

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

Note: Since data signals are not generally found in the air band, this feature does not work in the air band.

To turn on the data skip feature, be sure the priority fea- ture is turned off (see “Priority” on Page 28), then press
