Page 25

SCANNING THE STORED CHANNELS

To begin scanning channels, press SCAN. The scanner scans through all non-locked channels in the activated banks. When the scanner finds a transmission, it stops on it. When the transmission ends, the scanner resumes scanning.

Note: To scan in the trunk tracking mode, see “Scanning a Trunked Bank” on Page 36.

MANUALLY SELECTING A CHANNEL

You can continuously monitor a single channel without scanning. This is useful if you hear an emergency broad- cast on a channel and do not want to miss any details — even though there might be periods of silence — or if you want to monitor a specific channel.

Follow these steps to manually select a channel.

1.Press MANUAL.

2.Enter the channel number.

3.Press MANUAL again.

Or, if your scanner is scanning and stops at the desired channel, press MANUAL one time. (Pressing MANUAL ad- ditional times causes your scanner to step through the channels.)

To resume scanning, press SCAN.

DELETING A STORED FREQUENCY

1.Press MANUAL.

2.Use the number keys to enter the channel number containing the frequency you want to delete. Then press MANUAL again.

3.Press 0, then press E. The frequency is deleted.

Note: Channels with no frequencies are automatically locked out during scanning.
