Binghamton, NY Nov ten, 2009 #7 I am not familiar with meter operation, but I would suspect that it needs to send the switching voltages (13v for odd and 18v for even). And, if you have to see another sats it ought to ship the 22khz tone. That staying stated, https://dien-phuc-thinh.gitbook.io/dien-phuc-thinh/cap-tin-hieu-am-thanh-chinh-hang-tai-dien-phuc-thinh
