The main problem with the new RMN5068A Desk microphone that replaced the HMN3000 is that it works with the Motorola mobiles but doesn't work with dispatch solutions such as the MC series desksets and the Commandstar lite console all of which are manufactured by CML. What we discovered is the mic DC voltage supplied by the mobiles is around 5 to 7 volts. The mic dc that the CML products supplies is almost 12 volts. The HMN3000 tolerated the higher voltage without affecting the mike audio. The new RMN5068A can't tolerate that higher voltage and causes the mic amplifier circuit to go into distortion.
What is the function of each dip switch in the mic?
How do you separate the front and rear covers on the mic?
