Notices

After the OCXO module is installed, power on and start up the RF signal generator. During
the start-up process, the RF signal generator will recognize the OCXO module automatically
and be synchronizhed with the OCXO module. Note that at this point, external sync signal
cannot be connected to the RF signal generator.
Press Syst  Information  System Info; if the instrument interface shows that the
OCXO-B08 option is activated, the OCXO module and RF signal generator are successfully
synchronized; otherwise, the synchronization fails.

CAUTION

After the OCXO module is installed, the OCXO module will still be working if
you only turn off the power key at the front panel without cutting off the AC
power supply at the rear panel. Therefore, please remove the AC power plug
when you will not use the RF signal generator for a long period of time.
