If the machine is dead, then you probably have a bad battery. It should be changed every 3 to 5 years by the dealer. If it has been left too long, then this is a common symptom and the machine loses all programming. Otherwise, you may have a faulty power supply or mode lock unit. It sounds like you need to see a dealer about it. ------------------------------------------------------------------------

2. Master reset (All memory clear)
There are two possible methods to perform a master reset.
· MRS-1
Used to clear all memory contents and return machine back to its
initial settings and return keyboard back to default keyboard layout.
Procedure
1) Unplug the AC cord from the wall outlet.
2) Set the MODE switch to the (SRV¢) position.
3) Plug in the AC cord to the wall outlet.
4) While holding down JOURNAL FEED key, turn to (SRV) position
from (SRV¢) position.
· MRS-2
Used to clear all memory and keyboard contents.
This reset returns all programming back to defaults. The keyboard
must be entered by hand.
This reset is used if an application needs different keyboard layout
other than that supplied by a normal MRS-1.
Procedure
1) Unplug the AC cord from the wall outlet.
2) Set the MODE switch to the (SRV¢) position.
3) Plug in the AC cord to the wall outlet.
4) While holding down JOURNAL FEED key and RECEIPT FEED
key, turn to (SRV) position from (SRV¢) position.
5) Key position assignment:
After the execution of MRS-2, only the RECEIPT FEED and
JOURNAL FEED keys can remain effective on key assignment.
Any key can be assigned on any key position on the main keyboard

Hi. You may have a bad battery. This can cause lock ups. If it hasn't been replaced in the last 3 to 4 years, take it to a dealer to have the internal battery replaced. The battery will eventually leak all over the inside of the machine and damage it beyond repair. --------------------------------------------------------------------------------------------------
