To select the different display modes push the Display Mode Selector. The transition from one mode to
another may take a moment with the transition into the Diagnostic mode taking slightly longer. The
Selector is cyclical rotating through each of the modes. Once in the Diagnostic mode a quick push of the
Selector cycles through the various diagnostic sub-modes described above.
The following table describes the expected readouts in each of the above Base Station display modes. By
following the sequence you can understand what the various readouts and four character abbreviations
mean for the system.

Base Station Digital Display Activity Explanation
(assumes after initial power up – see Page 66 for a description of the Power Up sequence)
BASE RX (Base Station Receive Signal Strength)
BASE RX -9 Indicates that the Base Station signal strength is -9 dBm
BASE RX OPT Indicates that the Display is showing Optical link signal strength
BASE RX -9 Repeat of the Base Station signal strength
BASE RX OPT Repeat that the display is showing Optical link signal strength
This display cycle repeats itself and depending on timing may start with
either OPT of the strength measurement
CAM RX (Camera Unit Receive Signal Strength)
CAM RX ROPT Sequence starts with ROPT to indicate remote optical signal strength
CAM RX -9 Indicates that the signal strength from the Camera Unit is -13 dBm
CAM RX OPT
Indicates that the Display is showing Optical link signal strength
NOTE: the only way to distinguish between BASE RX and CAM RX is to check
the Display Mode LED indicator.
CAM RX -9 Repeat of the Camera Unit signal strength
CAM RX OPT Repeat that the display is showing Optical link signal strength
This display cycle repeats itself and depending on timing may start with
either OPT of the strength measurement – ROPT does not reappear in the
repeating cycle
