F1 Crony

[The_Vigilante]

I recently purchased a used Crony F1 from one of the members of this forum. It worked without problems sans remote control. I recently purchased the Remote Control unit so I could get more information regarding my loads. I took it out this AM to check some reloads. What happens is after I get thru shooting a string I press the button on the remote and first reading is Sn-I release the button and the next reading is 1-everything OK so far. When I press the button again I get a display of brackets "[ ]". If I press the button again it goes back to Sn. The company is closed today so can't contact them until Monday. Anyone here have any ideas as to what is going on? What I might be doing wrong? Or maybe it is the Crony or Remote Display unit? Thanks in advance.
