[SAC-HELP] calper & calib in pole zeroes

Greetings,
I am using the TRANSFER function in sac 101.1  to deconvolve the instrument
response from several observations. I am using pole zeros files and when I
run the function I get the following error msg and the macro gets aborted.
When I use sac 100.0, I get this as a warning but the macro is executed.
Where should I set the calper & calib values? or should they be in the pole
zeros files?

warning  msg:

Station (SA30    ), Channel (BHZ     )
    Nominal Calper not set. Setting Nominal Calper to -999.000000 to match
Wfdisc Calper
    Sensor Calper not set. Setting Sensor Calper to 1.000000 to match Wfdisc
Calper
    Response appears to be Un-Normalized.
    Waveform appears to be unscaled.
    Wfdisc calib value is (786432000.000000).
    Waveform multiplied by 1.000000 after deconvolution.

Any response is greatly appreciated.

Thank you.

Januka.
