NLG Home Game Change | Enabling DBV | Determining your SP and SS chip | Installing a Bell | Game Types

Replace your Slot Machine Glass pieces with the new ones that were sent to you in the kit. Some game kits only require 1 piece of glass.

Start with the top piece of glass and remove it by opening the machines main door and carefully lifting the old glass holder up and out of the cabinet frame. Install the new upper glass.

The Reels will be numbered in the order that they are installed in the reels from left to right.

Lay out the new strips on a flat surface and take a comparison look at the strips different symbols. If they are all the same and all the symbols line up with each other then you do not need to be concerned with which strip goes to which reel. If however, any strips are different from each other than you will need to install them in a particular order depending on the game.

 

Your new reel strips have small notches cut in them at the bottom. There is also a matching notch on each reel basket. The notches on both the reel strips and the reel baskets must
be installed so that their notches are aligned to together in the correct positions in their reel baskets. - In addition most (Not all) strips will be numbered either at the very bottom or on the back top side of the strip. Generally the lowest number strip will be installed in the left reel, usually marked as #1 and the next higher # strip will go to the middle reel and the last one installed at the most right side reel. – There is an exception to this rule that being if your reel strip set has different symbols, you will install the odd number strip in the middle or right side depending on your game.


The easiest way to locate the notches in the reel baskets is to place a reel strip into the left side groove of the basket that it is to be installed into and hold the strip at a 45 degree angle to the basket with one hand and use the other hand to rotate the basket slowly until you feel it catch on the notch. Then, proceed to roll the strip around the back side of the basket and as you do tuck both sides into the grooves of the basket until you come back around to where you started.
At this time you want to make sure that  the end of the reel strip overlaps the other end of the strip and that they are seated together with the self adhesive sticky surface on the inside of the strip. (You may have to use clear scotch tape to secure the strip to itself. If you did this correctly, you will not be able to see the notches in the strips after you are finished and the reel should spin straight and true numbers on the bottoms or back sides of the strips so that they are installed in the correct reel.

 

NOTE: - MOST GAME CHANGES ONLY REQUIRE THE "REEL" EPROM TO BE CHANGED. DO NOT REMOVE/CHANGE YOUR "GAME" EPROM, UNLESS YOUR NEW GAME SPECIFICALLY REQUIRES IT TO BE CHANGED. (If you do change the "Game" Eprom chip you will loose the operational function of your Bill Validator and it will require a special Set Chip to re-activate it) - Because of this, most Game Kits will not include the Game Eprom.  

 

Changing the Reel chip

 

Remove Coin Tray, hopper and tray.

Remove coin tray by pulling up on the black round tray knob, once it "unlocks" pull the tray towards you.

 

Locate the chip clearly marked as the "REEL PROM" on the main board and using a small flat blade screwdriver, gently pry up one side of the chip by carefully inserting the blade end of your screwdriver between the chip and its holding socket. - You will start at one end and then go to the other end and gently pry up on that side, then return to the side you started on until the chip is dislodged evenly from its holding socket. Try to pull it out as evenly and straight as you can so you don't damage or bend any of the chips 28 pin legs. If you do you can straighten them out again but just try to be as careful as you can.


 

 

Install the new "REEL" chip included with your game kit in the same direction as the old one that you just removed. This means the notch in the chip must install in the same direction. Use caution when installing the chip so that you do not fold over any of the chips pins .Go slowly and re-check all the legs as you go and again afterwards. If one or more of the legs do get bent, you must straighten it before proceeding. Next, push down on the top of the chip firmly until the chip is seated all the way in its holding socket.  


 

Initializing the new game

 

After installing the main system board, install the hopper and turn the power switch on. The machine should come to life and you should see a "61" displayed in the winner paid window. - You may see a 65, 66 or 67 in the window instead. See the below illustrations and pictures to see what you need to do for each code displayed

 

If you see a "65, 66, or 67"code after making a chip change - Power off the machine, then back on. You should then see a 61 displayed in the winner paid window.


 

When you get a 61 press and hold the white test button next to the power switch until you hear a "Ding"

 


Once you get a 61 1 close door completely and turn the jackpot reset key one time

 

Note: - A Common problem that occurs after a game change is that you will see a 61- 1 code  after you hold the test button in and hear the "Ding" but you close the door and turn the reset key and nothing happens. This is usually caused by an open door to the cash storage container or a misaligned Bill validator. - Check all your doors to be certain they are completely closed before closing the main machine door.
