Meta 357 Alarm Help - It's Stopped Sounding!

[Amber Phoenix]

I have an '03 Fazer 600, with a Meta 357Tv2 alarm/immobiliser. For some reason the alarm has stopped it's familiar beeps when it armed/disarmed. Indicators still flash correctly and immobiliser still kicks in when armed. Just no beeps.

Not checked if it sounds when trigged yet.

Any ideas what's up? Have I inadvertently triggered some funny quiet mode? Just been over the manual, but I can't find any reference to such a mode that has no beeping.

In the manual, does it mention 'winter mode'?

That's what my bike is on now, it basically still functions, but arm disarm is silent and it draws very little power from the battery.
