* Above 45ºC the laser aimer is disabled. In high temperature
environments the DS457 safeguards the laser from overheating by
monitoring the internal system temperature.
Note: Environmental and/or tolerance parameters are not cumulative. Perform a thermal analysis
if the application is subject to an extreme temperature environment.
