checking line module setting for 110V / 220V

 

Hi folks,

mayby I'm stupid, but I need guidance.
I want to make sure my HP85101 is set for 220V before connecting it to mains and powering it up.
The line module seems pretty much standard across the HP equipment of that age.
A lever next to the mains socket removes the fuse. Below the lever there is a little pcb plug that allows to change the voltage setting.
Is there a trick to remove that card? It seems to be stuck. Is there a locking mechanism or do I just not pull hard enough?
I don't want to break anything.

Thanks, Tom

As I recall, there should be a little hole in the small PC Board. Hook it with a Small Screwdriver or anything else you can hook it with, and pull.

there is small hole on card
use a hook and pull, swinging the card from side to side
There is no locking except fuse lever

Tom,

Give it a tug - they’re in there pretty tight! I just pulled one to be sure and unless someone has damaged something it should pull straight out.?

Most of my (many) items of HP gear arrived in the UK from the USA so I've met this issue a few times, what I do is:
Check that nothing is bent/twisted, take a pair of thin(ish) nosed pliers - with serrated jaws - grasp the back edge of board in the centre and with a silent prayer to the Gods of Incredibly Thin PCBs pull straight and firmly and out it will come!

I used a little hook like the ones you can buy at a hardware store and glued it into a small plastic rod

Many thanks for your great feedback.
It gave me enough courage to pull the little card out.
I found I had a pair of pincers with a hook on the tip.
No idea what it was originally for, but worked great.
:-)

Best regards,
Tom
