how many batteries and lifetime in unit
The headset requires 2 AA batteries. You should get 32-40 hours of use from those two batteries.
What are all the buttons and ABC switch settings for? I bought two and there were no instructions concerning all of the features. This is strange! I can not find any information online about this headset. Is there any printed information from GCA?
You can find the instruction guide at the link below.
