Ricoh Ft 4118 need to adjust exposure amd vsg

[Papo]

Cant find any documentation on this model need to darken up exposure and adjust vsg how do i get into sim mode ? What code should i use?
Any help would be apreciated!

There is 2 ways of getting in the SP modes

1. Press "All clear" (Yellow Button), "Stop Button" (Red Button) and then "#"
In this mode you have to press "." and then "#" to enter a value

2. Remove the back cover and set Dip Sw 4 on mainboard to on.

SP 48 = Exposure Lamp Adjustment.
SP 54 = Is Vsg. (To adjust the Vsg adjust the POD on the mainboard. Think
its the top one. VR101 or something. Memory is letting me
down)
SP 55 = Vsg & Vsp (If i remember correctly you hold in "0" to get the VSp)

Hope this helps.
