Through these 4 keys it is possible to read, modify, rewrite the timing sequence and
dethermalize the model. It is also possible to change the default settings and accurately
adjust the micro servo positioning. The function of each key depends on the state of the
Programmer and if it is pressed for a short or long time.
Automatic switch off and Programmer battery check
The Programmer goes to sleep if idle for about 120 sec. and wakes up by pressing one of
the keys. If the data have not been transferred to the Timer they will be lost. If the voltage
is insufficient, the Programmer displays
“
Battery low!
”
and goes back to sleep to prevent
the batteries from being harmed.
Notes about Programmer’s key pressing
The Programmer has only 4 keys. A long key pressure (press and hold) or a short
key pressure (press and release) may be required, depending on the situations and
according to the following rule: choices displayed in upper case (e.g. READ,
WRITE,..) require a long pressure, choices displayed in lower case (e.g. Servo,..) require
a short pressure
