9. NOTES ON REPLACING THE LITHIUM CELL AND RAM
(IC3 : TC5564APL-15)
• When replacing the Lithium cell (DEM 1001) in the
CONT unit of the commander block, clear RAM data
in the following manner.
If the data is not cleared, a malfunction may occur.
• How to clear
1. Set the power switch to OFF and all the function
switches of the commander block to ON.
2. While simultaneously pressing four keys, the volume
+ and - keys and the cancel A and B keys on
the remote control unit, set the power switch to
ON. A buzzer sounds in a few seconds, indicating
that the clear operation is completed.
(Note : An error may occur if you set the power
switch to OFF while pressing these four keys.)
When the data is cleared, the rate settings return
to their default values (3 tunes/1 $, 18 tunes/5$)
and all other data become 0.
Be careful when performing this operation as it
sets even the non-resettable data all to 0.
