Teejet Matrix not retaining date and time

[Northdowns Martin]

My Matrix 840 has stopped retaining the date and time after being switched off. It defaults back to 1/1/1970. Is there a battery I can replace or is a case of sending off to an electronics expert?

Probably is a backup lithium type coin cell or similar to keep the Real Time Clock (RTC) alive. Sometimes they’re user replaceable and sometimes soldered directly to the board, so bit more of a fiddle to replace.

If you're not comfortable cracking it open to take a look, I’d have a chat with Dave King Electronics.

Have you updated to latest software? I was having the same issue before updating.

Thats probably the answer as currently running V2.04 which looks well out of date. Been on to Teejet website they don't appear to support the Pro G software any more only the newer Pro GS.
