Vertex Standard VX-821-G7-5 PKG-1 UHF Portable Radio, FNB-V87LI Questions & Answers
While transmissing 'E7" is displayed in vertex repeater. how to rectify this problem?Manual says it is PA Unit Problem.Pls tell me a solution for othis problem.
This error arises when the PA module draws abnormal current. I had this problem because of a bad solder joint in the harmonic filter that is located directly following the PA module. Because of that, the PA sees a mismatch on the output. The VSWR sensor will not detect this because it is placed AFTER the harmonic filter. In my repeater this harmonic filter was inside a shielded module that was really difficult to remove. After I removed it, it turned out one of the caps in the filter was not soldered properly. I am not saying this will be the case in your repeater, it could be another problem but for me this solved the error code issue.
How to wire a fridge thermostat
Wiring a fridge thermostat typically involves connecting the thermostat to the power source and the compressor. Here's a general guide for wiring a 3-pin thermostat:
- Identify the Pins: The thermostat will typically have three pins labeled 4, 6, and 3.
- Connect the Power Source: Pin 4 is usually the common (C) terminal, which connects to the power source. This could be the live wire from your electrical supply.
- Connect the Compressor: Pin 6 is often the normally open (NO) terminal, which connects to the compressor. This allows power to flow to the compressor when the temperature rises above the set threshold.
- Ground Connection: Pin 3 is commonly the ground (GND) terminal. This should be connected to the ground wire for safety purposes.

Serial Number for KPG-790
All questions need FULL 'make model (what it is) first 3 words please.
Something to do with this? The serial number should on the label on the rear by the mains cable. This is a statutory requirement unless someone removed it to hide its identity.
