What to do if the red short/overload light is illuminated on Clear-Com Power Supply?

  If the red short/overload light is illuminated on your Clear-Com Power Supply, it indicates a short or overload on that channel, often due to a shorted or mis-wired cable or a defective remote station. To resolve this: * Remove cables one at a time until you locate the faulty line. * Check for shorts between pins #1 and #2. Once the short is removed, the PS-702 will automatically reset, and power will return within a few seconds. Also, check the remote station and replace it if necessary.

  If both red short/overload lights are illuminated on your Clear-Com Power Supply, it typically means the system is overloaded or there's a short in the multipair cable. To troubleshoot: * Remove cables one at a time to identify where the excess current is required. * Re-evaluate the system's current needs. Also, check for shorts between pins #1 and #2, removing cables one by one until you find the faulty line.

  If your Clear-Com Power Supply system isn't operating and there's no power to the PS-702, with neither the green power light nor any short/overload lights illuminated, the issue could be due to: * No AC power reaching the PS-702: Check the AC connection and cable, ensuring it's plugged into a dependable AC source. * An internal power supply failure: In this case, the unit requires servicing.

Why is there hum or buzz in my Clear-Com PS-702 Power Supply system?
- R
  randy74Aug 25, 2025
  If you're experiencing hum or buzz in your Clear-Com Power Supply system, it could be due to inductive pickup from nearby power lines or transformers, or an open 10? chassis ground resistor. Try relocating the main or remote stations away from power lines or transformers. Additionally, check the DC resistance for 10? between the chassis and pin #1 of any intercom connector.

  Laura AlexanderAug 28, 2025
  If you're getting system feedback (acoustical) with your Clear-Com Power Supply, it might be because the volume control at the remote station is set too high (adjust it), the channel is unterminated (set the PS-702 termination switch for that channel to the on position), or a headset extension cord is being used (which are not recommended).

  mary11Aug 31, 2025
  If you are experiencing excessive crosstalk with your Clear-Com Power Supply, the issue may be due to high DC resistance in the ground return (use heavier cable or add additional conductors to the ground return), multi-channel cable pairs that are not individually shielded (replace the cable with individually shielded pairs), or headset cables that are not wired or shielded properly (correct the wiring or use headsets with properly shielded wiring).

Why does the program signal sound distorted on Clear-Com PS-702 Power Supply?

  gardnercathySep 8, 2025
  If the program signal sounds distorted when using your Clear-Com Power Supply, it's likely due to an overload in the program circuit. Reduce the program-in level or decrease the gain of the program signal at the source, such as an audio mixer.
