Question: How to do a fast calibration of the bridge dealer with only 4 cards? (Basic)
A 4 card calibration is done if you insert 5, 7, Jack, and Queen of Heart as the first four cards of the deck of 52 cards the dealer read and deals.
When do you need a calibration – if you experience an increasing number of card read errors or for example if the dealer read red cards better than blue cards?
Please notice you can do a fast 4 card calibration (on each deck) or a thorough calibration of the bridge dealer’s UV readers with 2 * 52 cards – see more here. In most cases, 4 cards calibration would be adequate.
Please – before you start a calibration please control that the bridge dealer does not have dirt in the UV readers. Please blow gently to remove any dirt or remove it with a rubber blower. Please do not use a sharp device or anything that can harm the UV readers or transmitters.

A 4 card calibration is done if you insert 5, 7, Jack, and Queen of Heart as the first four cards of the deck of 52 cards the dealer read and deals and is recommended at the start of each game.
You can repeat the 4 card calibration as often as you like during a game
