Uniden America Corporation UB345 사용자 설명서

 
Weather Banks— 

frequencies are preset and allows the scanner to search 7 weather channels (NOAA, 

weather) 
 
Dimmer

 — lets you select the brightness of the display backlight. 

 — allows the scanner to trunk three trunking systems, Motorola and 

EDACS, at the same time, as well as conventional systems. 
 
Hypersearch

— lets you set the scanner to search at up to 270 steps per second in frequency bands with 5 

kHz steps, compared to the normal search speed of 90 steps per second.

 

 

— the scanner automatically scans up to 90 channels per second to help you quickly find 

interesting broadcasts. 
 
Memory Lock

 — lets you lock the scanner to help prevent accidental changes of the channels and the talk 

group IDs stored in the memory. 
 
Data Signal Skip

 — lets you set the scanner to skip non-modulated or data signals (such as fax or modem 

transmissions) during scan and searches. This lets the scanner avoid non-voice signals, making a search 
faster. 
 
Disconnect Tone Detect

 — the scanner automatically tunes to the trunking data channel when it receives a 

disconnect transmission. You can turn this off, so you can continuously monitor a channel with a weak 
transmission where conversations are often disconnected. 
 
Manual Access

 — lets you directly access any channel. 

 
Liquid-Crystal Display

 — makes it easy to view and change programming information. 

 
Display Backlight

 — makes the scanner easy to read in low-light situations. 

 
Key Backlight

 — makes the keys easy to read in low-light situations. 

 
Flexible Antenna

— provides adequate reception in strong signal areas and is designed 

to help prevent antenna breakage. Or, you can connect an external antenna for better reception. 
 
Memory Backup

 — keeps the frequencies stored in memory for an extended time if the scanner loses power. 

 
Wired Programming

— you can connect your scanner to a personal computer and program frequencies into it 

using an optional interface cable and software. 
 
Two Power Options

 — let you power the scanner using external AC power using the included AC adapter or 

DC power using an optional DC cigarette-lighter power cable.

 

 

— lets you turn off/on the key touch tone, error tone and confirmation tone. 

 
Weather Alert Indicator

 — your scanner also functions as a severe weather alert monitor. 

 
 
 
 
Your scanner can receive these bands:
