Note that the time setting must be a valid one for the clock to receive it. For example, a time setting of 10 minutes for one player and zero minutes for the other won’t be accepted by the clock. When programming the ZMF Tap N Set™ clock with a cellphone, the phone will vibrate and the clock’s LED indicators will momentarily blink to indicate that the operation was successful. The location of the NFC antenna in a cellphone can vary depending on model. The best way to find out where the antenna is located is to try tapping the cellphone against the clock using the bottom, middle, or top part of the phone until it connects.
