To Next PageTo Next PageWhy do my Kirby Morgan 37 Diving Instrument communications cut in and out when I wiggle the connector?
If communications only work when the connector is wiggled back and forth, there may be a break in the waterproof connector. If the connector is suspect, remove it from the line and test the line for integrity prior to replacing the connector.
What causes my Kirby Morgan 37 Diving Instrument defogger to stay on and the helmet to free flow?
If the defogger can’t be shut off and the helmet free flows through the defogger, it may be due to: * A damaged seat assembly or debris under the seat; clean and/or replace the seat assembly and check and clean the side block seal area. * The sideblock being damaged by debris; replace the sideblock.
What causes back-flow in the one-way valve of my Kirby Morgan Diving Instrument?
If the one way valve allows back-flow, it's likely due to foreign matter in the valve. Disassemble the valve, clean it, and rebuild it. Replace if needed.
Why doesn't gas flow through the one-way valve on my Kirby Morgan Diving Instrument?
If the one way valve doesn’t flow any gas, it's likely due to foreign matter in the valve. Disassemble the valve, clean it, and rebuild it. Replace if needed.
Why is the defogger valve knob on my Kirby Morgan 37 Diving Instrument hard to turn?
If the defogger valve knob is hard to turn, the valve stem may be bent. Replace the valve stem.
