Question about the HS-007 Plus

I had a question about the HS-007 Plus. Is there a frequency range for each of the 5 cellular lock functions that it searches?

Re: yes, but it is very small distance, as outpower is very low , only 0.5w.

If it is a range, what frequency band range is covered with the cellular lock function for each of the 5 presets?

Re: depends on local enviroment.

For instance - when the GSM 800/900 cellular lock function is locked is it locking and detecting the band range from 800 MHz all the way to 900 MHz or is it only the range from 800 MHz to like 824 MHz? Or is just 800 MHz?
Re:when you change to lock function, then detecting will not work,
Are you able provide what the MHz range is for each cellular lock presets below?
