SERVICE ADJUSTMENTS
Because this is not a hot chassis, it is not necessary to use an
isolation transformer. However, the use of isolation transformer will help
protect test instrument.
Adjustment must be done in the correct order.
> The adjustment must be performed in the circumstance of 25 °C ± 5 °C of temperature and 65±10% of relative humidity if there is no specific designation.
> The input voltage of the receiver must keep 100~240V, 50/60Hz.
> The receiver must be operated for about 5 minutes prior to the adjustment when module is in the circumstance of over 15 °C.
