Direct Search — lets you search for transmissions starting from a frequen- cy you specify.

Count Feature — lets you keep track of how many times your scanner has stopped on a channel.

Search Skip — lets you select up to 50 frequencies for the scanner to skip during a search, so you can avoid fre- quencies you have already discovered or that have a continuous transmis- sion.

Two-Second Scan Delay — delays scanning for 2 seconds before moving to another channel, so you can hear more replies.

Data Skip — skips data signals (non- modulated signals such as preamble signals for pagers) during scan, limit search, and direct search.

Lock-Out Function — prevents channels you select from being scanned.

Priority Channels — checks 10 spec- ified channels every 2 seconds so you do not miss important calls.

Automatic Modulation Mode — se- lects the modulation method — nar- row-band frequency modulation (NFM) or amplitude modulation (AM)

most often used for each band, and lets you manually override the preset mode.

Attenuator — reduces the scanner’s sensitivity to help limit reception to strong, nearby transmitters.

Memory Backup — keeps stored channel frequencies in memory for up to 3 days during a power loss.

CTCSS Option — with an optional CTCSS tone circuit board, you can use the Continuous Tone Coded Squelch System (CTCSS) to selec- tively listen to some business band and amateur radio transmissions.

Backlit Display — lets you easily see the indicators on the scanner’s dis- play, even at night.

We recommend you record your scan- ner’s serial number here. The number is on the scanner’s back panel.

Serial Number: _________________

Your scanner has the following pre- programmed weather channels:

162.4000 MHz (NFM)

162.4250 MHz (NFM)
