Omron RS4603

Postby afswift on Mon Sep 29, 2014 7:00 pm


I have just been given two Omron RS4603 cash registers which I wish to use in my pub.

Has anyone on here got a copy of the programming / user manual that they could e-mail to me?

Thanks in advance

I am in exactly the same position, my RS4603's were here when I bought my pub last year.
All I have found out so far is how to change the VAT rate.

Key to Program
SubTotal 1234 NoSale, Enter program mode
26 @ XXXX SubTotal NoSale, Set VAT rate XXXX = VAT %
SubTotal 0000 NoSAle, Exit program mode
Key to REG

I need to access reports etc and turn on Journal print

All help appreciated

the very best of luck to the pair of you!
not only are they as old as the hills but you also have to be a rocket scientist to understand the manual - should you be lucky enough to find one all for saving a few bob
but in the long run you are investing in a total nightmare!!! [ive been a till engineer for 35years and i wouldn't take on one of these! !dunce ]

The Omron RS46 range was a cracking bit of kit in the day, hence why large breweries and motorway service stations installed them. They were easy to fix, and easy to program once you understood the Omron principles of S and P mode. They were great machines.
The RS4603 was one of the last models from what I remember but would have been problematic if the ROM became corrupt and you did not have the facility to load the ROM back in using the specific Omron built FDK and the Rom on disk (That is as I remember it, but stand corrected)

Tills are still in daily use and so is the computer that came with them, they were installed by Greenalls Brewery (UK) back in 1995
The screws have fallen out of the display hinge on one till, can you remember if the top case is screwed or clipped together?.

Sorted Omrons and programmed them for years, any company like Omron who make medical equipment too in my book cant go wrong. Dont see many Casio or SPS life saving machines in hospital. thank God. I have still got Omrons out there 25 years old and still working.
