7.10 Using the Acquisition Memory Backup Function

Backup Procedure

1. Turn ON the acquisition memory backup switch on the right side panel of the

DL750/DL750P. The acquisition memory backup starts.

2. To stop the acquisition memory backup, turn OFF the acquisition memory

backup switch.

The backup time varies depending on the operating environment. See section 19.5.

Note

• When using the nickel hydride rechargeable batteries, be sure to charge them before use.

(The DL750/DL750P does not have a charge function.)

• You cannot check the battery level on the DL750/DL750P. Use a commercially sold

battery level checker or other similar devices.

• For a description of the backup operation, see appendix 9.
