Testing
WARNING
Failure to test your Slugbuster coin acceptor according to these instructions may result in
conditions which can cause property damage, bodily injury and/or death.
Test the selectivity adjustment and crediting function
1. Be sure the power to the unit is turned OFF
2. Insert a sample of the coin or token you want the unit to accept (see ‘Inserting Coin’ below). If you’re using something other than
a US quarter, also see Adjusting Selectivity on page 2.
3. Hook up a 24-volt AC power supply and a coin counter or 24-volt AC pilot light.
4. Turn the power ON
5. Insert a batch of coins into the top of the coin chute. You will need to repeat this several times, watching for the events listed
below. Include batches of ‘good coins’ (coins matching the samples in your Slugbuster) and some slugs common to your area.
- As each good coin is inserted, the indicator light will flash once, or the counter will count up one. All good coins should be
accepted and credited, as indicated by the light flashes or coin counts.
- All slugs should be rejected. Be sure to remove the rejected coins from the return cup, or they may jam the unit.

Inserting Sample Coin or Token
Read this section carefully before purchasing tokens or attempting to change the sample coins.
For proper operation, there must be a sample of the coin you want the unit to accept in the sample holder.
All changes to the type of sample coins accepted must be approved by Parker Engineering and Manufacturing. For example, the Su-
san B. Anthony dollar coin is not currently compatible with P-55 Slugbuster models. Please call us for details at 800-752-0762.
- Do not use a US quarter dated 1965 or 1974 as a sample.
- The 70/30 copper/zinc alloy token is not recommended since it is widely used in video games.
- Do not use aluminum tokens, as scrap aluminum is widely available and cannot be tuned out with selectivity adjustments.
- Copper/nickel alloy tokens are not suitable for use. Given their production variations, they cannot be reliably distinguished from
nickels.
Before investing in tokens for your Slugbuster I, check your local area to be sure there are
no other operators using similar size tokens of the same alloy.

Inserting Sample Coin or Token
(continued…)
To insert or change the sample coin:
1. Locate the sensing coil on your unit
2. Slide it in the direction of the arrow on the label, against the
Coin Slide Rail

spring tension and remove the existing sample
3. Insert a new sample coin or token into the sensing coil and
allow the spring tension to tighten the sensing coin against
the sample. The sample must be centered under the sensing
coil and firmly seated between it and the coin slide rail, as shown.

Adjusting Selectivity
Adjusting Sensitivity
Do not adjust the selectivity unless your unit malfunctions as described in ‘Testing’ on page 1.
Your Slugbuster has been factory pre-set to accept US quarters and reject common slugs. If you wish to use a sample other than a
US quarter, first insert your sample (see ‘Inserting Samples’ above). Then check the unit’s performance as described in ‘Testing’ on
page 1 to determine if you need to readjust the selectivity for your sample.
Use caution when adjusting the selectivity trim pot (potentiometer). It is extremely sensitive and very little movement will cause a
change in performance. The full range of movement is 240°, or less than one turn. If you turn it too far either way, it will break and
void your warranty. Turn the trim pot counter-clockwise (ACCEPT) to accept more borderline coins or tokens; turn clockwise
(REJECT) to accept fewer kinds of slugs. NOTE: the unit must be powered up to make these adjustments.
For best results, use this procedure to adjust the selectivity:
1. Locate the sensing coil on your Slugbuster. There must be a sample coin or token in the sensing coil;
check to be sure the sample is centered in the sensing coil and properly seated and secured.
2. Remove the plug from the lower right corner of the electronic box lid, exposing the selectivity trim pot.
3. Using a plastic stylus, turn the selectivity trim pot fully clockwise (REJECT). This should make the unit
reject all coins, tokens and slugs.
4. Begin dropping your good coins into the unit, slowly turning the trim pot counter-clockwise until your
Slugbuster begins to accept them. Turn the pot an additional 2-5 degrees counter-clockwise and stop.
5. Replace the plug in the trim pot. This completes the adjustment.
If the unit is accepting incorrect coins, turn pot counter-clockwise;
If the unit is rejecting good coins, turn pot clockwise
.
After Completing the Selectivity Adjustment, repeat the Testing Procedure on page 1.
When you are satisfied that you have the unit adjusted properly, be sure to REPLACE THE PLUG to protect the
electronics from dirt and water damage.
Installing the unit without the plug in place may void your warranty.
Cleaning Your Slugbuster
Clean your Slugbuster with a soft cloth and warm water. DO NOT use oil or other corrosive liquids.
