Once a value has been set in the echo field, one of the four ENTER
keys is then used to set the selected parameter value to the echo field
numerical value raised by the exponent of the ENTER key pressed.
Any attempt to set a selected parameter to a value outside the specifi-
cations will result in setting the parameter to its limit value.
If entry of a parameter value is not allowed, the Entry Disabled LED
(on the right of the Field Entry keys) will flash indicating that the se-
lected value cannot be changed.
Two keys on the left of the Field Entry controls (refer to Fig. 2.3).
"No": Selects the number of the actual front panel test set-up. The
range is 1 to 4, corresponding to the 4 complete test set-ups available.
Pressing the key for a second time switches between "Field Entry
Enable" and "Disable". The Entry Disabled LED will light when entry is
disabled.
"Parameter": Selects the set-up sequence for step-by-step guidance
through the test parameters. Pressing the key selects the "First" pa-
rameter, whose LED will light, and causes the "Parameter" LED to
flash. Consecutive pressing of the key will select the "Next" parameter
according to the set-up sequence. When an auxiliary instrument is
connected to the 1050, the set-up sequence will automatically include
the associated Special Parameter(s). The LED display will show the
parameter number and the actual parameter value with the Aux. LED
(on the generator display) lit. Other Special Parameters can be select-
ed using this key, refer to section 7.2 for further description of the
Special Parameters.
Single key on the left of the compression meter (refer to Fig. 2.4). It is
pressed together with the required numeral to reset the controller to
the following conditions:
"Reset 0": Has the same effect as switching the instrument "Off" and
then switching the instrument "On" again.
"Reset 1" to "4": Sets the actual Front Panel to the set-up conditions
stored in Front Panel 1 to 4, respectively.
"Reset 5": Sets the actual front panel to default values. Refer to sec-
tion 7.3 for further details of the default values.
