Relay Clicking Noise in Standby Mode, Power Problem - Technical Bulletin - Revision 1

Oct 12, 2026

Technical Bulletin addresses a standby-mode issue where switching from a digital channel to Standby can produce a clicking noise from the main relay on the G1 board. In some cases the noise occurs every 20 seconds; in others it appears every few minutes. The problem is absent during normal operation. If there is no power and the LED flashes nine times, the cause is a digital software error. Resolution requires upgrading the digital software DM2.5.106 (or lower) to the latest version using the specified DM*****.ZIP package and Memory Stick procedure.
