SL1100 - SLT Recall button doesn't hold call?

[Lectrician]

As the title really - I have tried three standard SLT phones on the SLT extensions, and neither one will place a call on hold by pressing the recall button? V7.01. Going by the manuals, you use recall to place a call on hold and to transfer. Any ideas why this would be? I cannot find a flash/recall time setting to tweak?

Thanks.

I found 82-04, have tweaked, but still nothing. I am wondering if the system is perhaps faulty?

82-04 is where it all happens

See pic below for the settings which WORK!

The default settings do not work out the box - Tried a new system today, and it behaved in the same way.

The new one, out the box, no programming, none of my three SLT phones would place a call on hold. There an up to date CD-ROM with literature, and a small note in the envelope saying about SLT settings needing to be set. Made the changes exactly as documented, BOTH systems now work fine!

The critical timing is to make sure the Maximum Break Time is less than the Minimum Hook Flash Time. By default, they are not.
