2.4.1500-08 SERIES CHANGEOVER CARD

The 500-08 Changeover Card is fitted at the left of each frame. Make sure the metal tab is hooked into the clip on the side cheek. Ensure the top and bottom edge connectors are both making good contact. The current version of this card is:

500-08-10 dual changeover for fault tolerant systems. There are no LEDs or other external indicators on these boards.

NOTE: For non fault tolerant systems (i.e. those fitted with only the main talkback and TDM controllers) we recommend that the 500-08-10 link is set to the “left” position.

The system controllers can be forced to left or right side operation. The default is Auto mode where the left controller is designated "main" and the right is "standby".
