DPO4104 Battery Removal and sanitiziation procedure

Does the Tektronix DPO4104 have a removable battery? If so, is removal of the battery necessary to clear or sanitize the DPO4104?

In looking through the sanitization procedure (see attached), does "remove power" mean merely power down the the DPO4104, unplug it from the wall outlet, or remove a battery?

The only battery is a dry 3V 150mAh, lithium button cell to maintain internal code and non user accessible data, no need to remove for Declassification/sanitize.

The "remove power" is only power down the DPO4104, unplug it from the wall outlet.
