5.6.2 Test of data recording to the fiscal memory
This test checks the ability to record the testing data to the fiscal memory. It provides for recording “AA” and “55” bytes to the testing
field of the fiscal memory. The first record of “AA” byte is performed on 1FE00 address and “55” byte on 1FE40 address. The next
performance of the test shifts the record by one address. It is possible to perform 64 tests altogether.
The method for starting the test:
1. Switch the cash register to the programming mode “P”.
2. Press the number 720 on the numeric keyboard.
3. Press
l
[Multiply] button.
The process of testing:
1. The control data are read and verified from the fiscal memory.
2. The first unrecorded byte, on which the “AA” value is recorded, is searched from 1FE00 address.
3. The first unrecorded byte, on which the “55” value is recorded, is searched from 1FE40 address.
4. The result of the test is displayed on the display and printed on the cash register printer.
Test evaluation:
** TEST **
720 XX Error
Incorrect test evaluation Correct test evaluation
** TEST **
720 OK
Fault description (XX) is defined:
1X - the first control data was not correctly read and verified from the fiscal memory.
2X - the second control data was not correctly read and verified from the fiscal memory.
30 - “AA” byte was not correctly recorded.
40 - “55” byte was not correctly recorded.
If the test of recording to the fiscal memory is evaluated incorrectly, gradually carry out the following test.
5.6.3 The operating voltage control for the fiscal memory
The VFD and VFP voltage values are very important for correct data reading from the fiscal memory and for correct data
recording to the fiscal memory. The values of these voltages depend on the control of VPP-GEN signal. By controlling
the VPP-GEN signal the test enables the measuring of the values of these voltages with an ordinary voltmeter.
The method for starting the test:
1. Switch the cash register to the programming mode “P”.
2. Press the number 730 on the numeric keyboard.
3. Press
l
[Multiply] button.
