Just make sure it is on switched (accessory) power, not always hot (battery) - it WILL draw some current even when not charging your phone, and if you don't switch it, it WILL run your battery down at the most inconvenient time.
This is my opinion, not Aeroflex's.
I WILL NOT give you proprietary information. I make too much money to jeopardize my job.
I AM NOT the Service department: You want official info, manuals, service info, parts, calibration, etc., contact Aeroflex directly, please.
