7 Check Device Signal Levels
The signal levels for all wireless devices and RCCs must be checked. This menu will
display the signal levels in dB for each wireless device and RCC over a 24 hour
period, listed in Loop and Address Number order. After the system has been
running for a 24 hour period, the device signal levels should display 24dB or
above and the RCC signal levels should display 20dB or above. If any devices are
under the signal level requirements, check the owchart On How to Improve
Device Signal Levels section for guidance.
