Hard reset on V985?

[Telkar]

Does anyone remember how to do this? My V985's volt meter is way, way off. I'm hoping a hard reset will fix it, unless the volt meter is adjusted via an adjustable pot. If it is, would anyone happen to know which? I have no issues with cracking it open.

It's on page 8.

I have no clue how I missed that.....gah. Thanks. It's on page 10 for the reset by the way. If it doesn't work...I'll be asking how to crack this old case open. I've never opened any of my old style bel's. never had to.

No dice...Can someone tell me how to pop the front off of these old style cases before I take a shotgun to an otherwise perfectly good 985?

First unscrew the two case screws under the unit. Now put the unit upside down on a table edge and put quite a bit of pressure on the front of the display and the back of the detector, like you are trying to break it in half. The front plastic should pop free. Just do not put pressure on the buttons or you will need to replace them too.

I don't think there is a pot for the voltage display though

EscortRadar, thank you for your prompt and very helpful reply. Seems to be a cold solder on the pcb, but everything else is still working as normal so I'm not even going to attempt trace it down right now.

There are no pots in the unit. The voltage measurement is done via a simple resistor voltage divider circuit that feeds an ADC (analog to digital conversion) input on the microprocessor.
