(*)Parameter1
The Projector has an incremental counter which counts Lamp Operation Time at 1 time in
every 4 minutes.
Parameter 1 shows this counter value.
The parameter type is "numeric".
Actual lamp operating time is obtained by converting the Parameter 1 value into signed
2-byte binary hexadecimal and dividing it by 15.
