The next automatic selections are made when this tuning function is activated:
– if transmission data is 0, 1 or random then continuous 1 data is selected
– active unit = TX
– the base power level is selected
– operation mode = burst
– channel = 661
The cursor is shown on the tuning position. Next value is selected with arrow
keys.
arrow keys will cause power changing. When these keys are used the coeffi-
cient value is updated on the tuning window.
When save or exit selection is used, the power value checking is made and if it
is not succeeded, error message is shown. The test checks if all power coeffi-
cient values are in the same bigness order as power levels in the table.
When TX power tuning is ended and if the power values are not acceptable,
the error message is displayed and the user is asked to continue or break the
tuning. The next answers and responses are in use:
Key Response
N or Esc The tuning is continued
Y The tuning is ended without EEPROM writing and
power coefficients are asked from EEPROM
(this is also informed to a user)
other key –
If the power tuning function is ended and EEPROM values are not received or
EEPROM fault is noticed, an error message is shown. Error message asks to
check M2BUS interface or set factory values. When any key is pressed, adjust-
ment menu is selected and PC values are used as power coefficients, even
though they have wrong values.
