This indicates a potential laser problem that could result in link failure and should be referred to the manufacturer For very short range links the MPD may read higher than normal because it is detecting transmitted power from the remote link as well This is only a problem for monitoring purposes and will not degrade the link performance in any way The Commands Menu includes simple commands which could be sent to the TereScope system The Reset command resets the TereScope firmware which will reset parameters to their power on default values The link may be lost for a short period of time during the initialization sequence so this command should only be used if the system appears to be unstable The EEPROM Load and Save commands allow the user to modify certain power on default parameters for those systems which include internal EEPROM Save will store the current values to EEPROM making them the new power on defaults Load will restore values from EEPROM undoing any changes made since power on Care should be taken in writing to EEPROM to make sure that the system is stable with the new values All values stored in EEPROM are changed through Advanced Menu settings and the warning that appears should not be ignored The Video Source commands allow the user to switch between internal and external cameras for those systems which include both The Advanced Menu brings up additional windows for advanced options In most situations these options sho
