PL-680 Radio FM Dial Tuning Full-Band FM/MW/SBB/PLL SYNTHESIZED Stereo Radio Receiver Portable Speaker PL680

Descriptions:

- Can receive FM stereo, AM, long wave, short wave, shortwave single sideband (SSB) and aeronautical communication signal band signal, high sensitivity, good selectivity, beautiful sound, easy operation

- FM reception coverage 76-108MHz range, can receive Chinese, Western and Japanese FM radio frequencies, but also to listen to some of the domestic campus radio and TV audio

- Shortwave single sideband (SSB) divided upper sideband (USB) and lower sideband (LSB), independent reception

- Ability AM synchronous is applied, the second technology, which greatly improve the reception sensitivity, selectivity and anti-mirror, adjacent interference

- Features FM / SW external , and high / medium / low sensitivity control switch 3 files, facilitates remote receiver (DX)

- Six tuning modes: manual search radio frequency (VF), direct dial frequency input, manual search stored radio (VM), direct dial input stored radio addre, the browser

automatically search for radio frequency and radio frequency stored

- Can be manual, semi-automatic (ATS) to store up to 2000 search for radio frequencies. Of which 800 are stored by the band (FM / AM / long wave / Air Band each store 100, HF / SSB each deposit 200), and the remaining 1200 frequencies can be arbirily categorized under 12 pages (12 x 100 )

- High sensitivity and high quality speakers, sound good; with high / ba control switch, listen to different programs to meet the needs of timbre; audible FM stereo radio with headphones

- Friendly interface, easy to operate, with a very useful multi-function dial adjustment knob, can be used to set the time, adjust the frequency, select the memory page and addre

- Dual regular boot function, the boot can listen to the stored radio frequency

- Intelligent switch: You can set the power to 120 minutes after the automatic shutdown can also cancel the automatic shutdown

- Use Section 4 R6 (on the 5th) battery-powered; the machine is with intelligent charging function

- Equipped with a dedicated power adapter, external , stereo headphones, and protective cover
