Program module
The program modules discussed here is the one that used as

Program modules
According to the need, the desired program module is
connected for an immediate program execution.
CD Two program modules can be used at the same time.
® When used as the program module, no user area can be
contained. But, if the module has been divided into a
program module and a user area using the INIT state-
ment, only the declared user area conforms to the user
area of (1).
® Creating the program rnodule,
After declaring the program area with the INIT state-
ment, the program is written or loaded to that area.
Ci) The memory protected CE-159, CE.161, or CE-1600M
must be used for the program rnodule,
RAM file module
With this usage, the completed program or data are saved
into the memory module, to be loaded onto the user area
when so required.
If used as a RAM module, the rnodule is not included in the
area.
CD The module that can be used the RAM file module is
the CE-161 and CE-1600M.

file module can be known by means of the FILES
staternerrt or LF ILES statement. I t is possible to change
the name or delete the program or data.

4. Consumption current test
1. Static electricity stored in human body must be released
before removal of the board,
2. First, remove the lithium batterv, and check for a short
circuit between electrodes and diodes using an ohrn-
meter (R x 1 range),
3 Connected the 3VDC power supply source as shown in
the figure below and check that the consumption power
is less than 8 microamperes.
