The manual is in English (which is not very legal) and fit on an A4 sheet.
There is a difference between the advice on the case and those mentioned in the user manual about the adjustable gain.
On the case: 0 ~ 10dB Gain Control
On the manual: 0 ~ 12dB Gain Control
In operation the casing hardly heats. There is no on / off button.
I did not find any information on the power consumption of the device.
With the antenna amplifier are supplied two screws that I have not used.
Personally, I find this antenna amplifier, 4 channels, perfectly fulfills its task.
For the moment ... ;-)
