In addition, the two optical sensors must be cleaned periodically. Use a cotton swab daubed in isopropyl
alcohol to wipe the inner wall area inside the first two inches of the coin slot.
If the unit malfunctions and a good cleaning does not solve the problem, reprogram the acceptor as
described in Programming the IDX Acceptor.
The unit comes equipped to accept either U.S. quarters or dollar coins. The unit will also accept site-
specific tokens.
In order to complete the programming you must have six of each of the tokens and coins you wish to
accept. It is very important that you follow these directions exactly. The IDX acceptor will average the
variances in these different sample coins during programming, and calculate a more accurate reference
model. Using less than six different coins will invalidate the average variance generated by this process.

Note:
The IDX can ONLY be programmed with the SentineI at the Test Devices - Test Coin Acceptor
screen. When inserting coins into the IDX, you must be sure to close the cover completely.
Please refer to the block diagrams shown below while programming the IDX coin acceptor.

You must answer the following questions before proceeding with the programming of the IDX coin
