IV. Advanced Functions
The advanced functions include a base station shift warning. We recommend you
become familiar with the basic functions before operating the device, or operate the
device under the guidance of a professional.
4.1 Base station shift warning
If the base station is tilted or moved by impact, AllyPad will alert the user that the
base station coordinates have changed. The coordinates that are collected after a base
station shift will be inaccurate. Power cycle the base station and correct its position before
continuing work.
FCC Statement
