an isolation transformer. However, the use of isolation
transformer will help protect test instrument.
(2) Adjustment must be done in the correct order. 
(3) The adjustment must be performed in the circumstance of
25 ºC ± 5 ºC of temperature and 65 % ± 10 % of relative
humidity if there is no specific designation. 
(4) The input voltage of the receiver must keep AC 100-240
V~, 50 / 60Hz.
(5) The receiver must be operated for about 5 minutes prior to
the adjustment when module is in the circumstance of over
15.
In case of keeping module is in the circumstance of 0 °C, it
should be placed in the circumstance of above 15 °C for 2
hours 
In case of keeping module is in the circumstance of below -
