- Close Call RF Capture Technology - you can set the scanner so it detects and provides information about nearby radio transmissions.
- PC Programmable - lets you program your scanner using user PC.
- Custom Search - lets you program up to 10 custom search ranges and search any or all of those ranges.
- Quick Search - allows you to enter a frequency and start searching up or down from that frequency
- Turbo Search - increases the search speed from 100 to 300 steps per second automatically for bands with 5 kHz steps
- Search Lockouts - allows you to lock out up to 200 search frequencies (100 temporary and 100 permenant) in Custom, Service, Close Call, or Quick Search modes.
- Lock-Out Function - lets you set your scanner to skip over specified channels or frequencies when scanning or searching. You must manually unlock these channels.
- Temporary Lock-Out Function - lets you set your scanner to skip over specified channels or frequencies when scanning or searching. You must manually unlock these channels.
- Priority Channels - You can program one channel in each bank as a priority channel (10 priority channels total). The scanner checks that channel every 2 seconds while it scans the bank so you do not miss transmissions on those channels. (Default=Priority Off)
- Priority Scan - lets you set the Priority feature to check each channel every 2 seconds regardless of whether or not the scanner is receiving transmissions.
- Priority Scan with Do Not Disturb - lets you set the Priority feature to check each channel every 2 seconds as long as the scanner is not receiving transmissions.
- Duplicate Channel Alert - lets you know when you have entered a frequency that is already registered on another channel.
- Channel Storage Banks - the scanner has 10 banks. You can store up to 50 frequencies into each bank (for a total of 500 frequencies), so you can more easily identify calls.
- Two-Second Scan Delay - delays scanning for about 2 seconds before moving to another channel so you can hear more replies that are made on the same channel.
- Do Not Disturb - prevents the scanner from interrupting transmissions during receiving.
- Ten Service Bands - frequencies are preset in separate Weather, Police, Fire/Emergency, Marine, Racing, Civil Air, HAM Radio, Railroad, CB Radio, and Other (Other = FRS/ GMRS/MURS) bands to make it easy to locate specific types of calls
- Key Lock - lets you lock the scanner’s keys to help prevent accidental changes to the scanner’s programming
- Direct Access - lets you directly access any channel.
- Two Level Display Backlight - Two brightness levels make the scanner easy to read in low-light situations.
- Direct Access - Lets you directly access any channel.
- Flexible Antenna with BNC Connector - provides adequate reception in strong signal areas and is designed to help prevent antenna breakage. You can also connect an external antenna for better reception.
- Memory Backup - keeps the frequencies stored in memory for an extended time if the scanner loses power
- Three Power Options - Use the supplied USB cable to charge the SR30C through your computer or other USB charging port. You can also power the scanner using two AA rechargeable Ni-MH batteries (not included) or optional alkaline batteries.
- Key Confirmation Tones - the scanner sounds a tone when you perform an operation correctly, and an error tone if you make an error.
- Battery Low Alert - warns you when battery power gets low. The Battery Low icon flashes (BATT) and a battery low tone sounds every 15 seconds until the scanner is recharged, turned off, or drained completely.
- Battery Save - works when there is no transmission for 1 minute in Scan Hold mode and in any Search Hold mode (does not work in Priority Scan and Close Call Scan modes). This feature turns off RF power for 1 second and turns it on in 300ms intervals to extend the battery live.
- Scan/Search Delay/Resume - controls whether the scanner pauses at the end of the transmission to wait for a reply. You can set the Delay time for each Channel, Close Call Search, Custom Search, and Service Search mode.
