The RXT-1200 and TX300s platforms offer low-power standby mode, which can be used for faster start or to keep the optional Atomic Clock in holdover mode. Simultaneously press the HOME+ESC buttons to activate.
The RXT-1200 and TX300s platforms offer a useful Standby Mode (Sleep Mode), that shuts down all its hardware functions, except for the internal Atomic Clock (optional) and keeps the main CPU in sleep (low power) mode. It provides two main benefits:
- Very low power consumption during transit between jobs.
- Fast boot-up: <5 seconds.
- Keeps the Atomic Clock fully powered and operational, retaining time sync in holdover mode.
To activate the Standby Mode, simultaneously press the 
HOME + 
ESC buttons simultaneously, until a tone (beep) is heard. The Power LED will remain Green to indicate the test set is still "ON".
During Standby, press the 
HOME button to check the status of the test set's battery capacity, estimated battery autonomy in sleep mode, and the total time elapsed since it was put to sleep. Total time is important when using the Atomic Clock in holdover mode, since the longer the unit is kept in standby, the more the time sync would drift (inaccuracy uncertainty increases).
Press HOME + 
ESC again, to bring the instrument back to full operational mode, then launch the test application(s) and run the necessary tests.
