3. Fully charge the 835-3 after running it from the battery for an extended
period of time.
4. If an 835-3 with internal battery will be stored for a long period of time, fully
charge it before storage, then remove the power adaptor and make sure that the
power switch is in the OFF position. After storage, first charge the unit for 4-6
hours.
To replace the battery at the end of its lifetime, please contact BNC or one of its
distributors.
Before using the 835-3 in battery mode for the first time, the battery must be
fully charged.
Batteries must be disposed off according to the local environmental regulations.
8. Extended Power Range (PE/PE2 Options)
The 835-3 is available with options extending the power range towards lower power
levels.
With these options installed, the minimum settable power level in CW operation is
extended down to –150 dBm. For the guaranteed minimum power level, please consult
the respective datasheet.
In POWER SWEEP Mode, the user shall avoid running sweeps over large power ranges
(> 30 dB) for extended periods of time, as this will result in continuous switching of the
mechanical attenuators and thus reduce the lifetime.
In sweeps where the mechanical attenuator is switched, the minimum dwell time
increases to 20 ms.
9. Maintenance and Warranty Information
