EYFR03 User Manual 20 of 110 v1.6.0
Chapter 1: Overview 20 January 2020
For signal strength, a less negative number indicates a better signal (-50 dBm is better than -60
dBM). The screen shows a color based on the quality of the signal. If the tool has not
communicated with the box recently, box for the tool will have a white background with the text
colored to match the color of the last signal strength received.
• Green – The signal from this radio is strong and will work at best performance.
• Yellow – The signal from the radio is weaker than recommended for best performance. The
radio should work but may have slower or occasionally interrupted communication with the
unit.
• Red – The signal from the radio is weaker than recommended for any use. The radio may
successfully transmit some results but will frequently have slow or failed communication
with the unit. If only one tool is red, bring it and unit closer together. If multiple tools are
red, consider using a different radio channel (changed from the Qualifier Settings screen).
