2.4.1 500-08 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".
