[TenTec] [english 100%] Re: Orion s-meter calibration

[Holger Göckritz]

Hello
About S-Meter-Calibration for Orion 565.
Use the Potmeter at the Frontplate up and near the S-Meter, make with a 
small screwdriver the adjustment  to get the maximum Number 255 with the 
MULTI- Knop for S9 plus 60dB.
Be carefull about the Settings of S1 Value, S1 is the startingpoint for the 
S-meter.
I thing it is for PREAMP- Button on ,but i have it done with PREAMP off and 
for adjusting the S-Meter with a generator use for example S9 the S8 Value 
and so on one down!
