time limit (by default, 30 minutes).
When the register goes to the power save mode, all display lights will turn off except the decimal point at the left
most position of the lower line. The register will return to normal operation mode when any key is pressed or a
mode is changed with the mode key. Please note when the register is recovered by a key entry, it is invalid.
After the recovery, start the key entry from the beginning.

• When you make an entry beyond a programmed amount entry limit: Check to see if the entered amount is

correct.  If it is correct, it can be rung up in the MGR mode.  Contact your manager.
