All Of The Registers Where You Previously Stored Instrument States Are Empty; Wrong State; The Power Supply Has Shut Down - Agilent Technologies E8241A User Manual

Solving Problems
If You Encounter a Problem
All of the Registers Where You Previously Stored Instrument States
are Empty
The save/recall registers are backed-up by a battery when line power to the signal generator
is not connected. The battery may need to be replaced.
To verify that the battery has failed, do the following:
1. Turn off line power to the signal generator.
2. Unplug the signal generator from line power.
3. Plug in the signal generator.
4. Turn on the signal generator.
5. Observe the display for error messages.
If either error message −311 or −700 is stored in the error message queue, the signal
generator's battery has failed.
6. Refer to the service guide for battery replacement instructions.
Saved an Instrument State in a Register but the Register is Empty or
Contains the Wrong State
If you have, intentionally or unintentionally, selected a register number that is greater than
99, the signal generator will automatically select register 99 to save your instrument state.
If the register number you intended to use is empty or contains the wrong instrument state,
do the following:
Press > >
Recall 99 Enter
This recalls register 99. The lost instrument state may be saved there.

The Power Supply has Shut Down

If the power supply is not working, it requires repair or replacement. There is no
user-replaceable power supply fuse. Refer to the service guide for instructions.
