MaxPort FAQ


Q. I adjusted the brightness in my MaxPort glasses but the image on the TV is not affected. Is there something wrong with the MaxPort?

A. No. The brightness controls on the MaxPort control box only affect the image being viewed inside the MaxPort glasses. Any brightness adjustment needed when using the MaxPort with a TV needs to be made with the TV’s brightness control function.


Q. How long does my battery included with my MaxPort last per charge?

A. A 550 series battery is included with your MaxPort system. The 550 series battery will last approximately 2-1/2 hours per charge. If purchased, the 750 series battery will last approximately 4-1/2 hours.


Q. How long does it take to completely recharge my battery?

A. If you own a 550 series battery, it should be left to charge for a minimum of 3 hours. The 750 series battery should be charged for a minimum of 5-1/2 hours.


Q. If I use the provided A/C power supply with the battery still in the MaxPort control box, will it harm the battery? Can the battery be charged while in the control box?

A. No. The A/C power supply will override the battery if it is in the control box. Leaving the battery in place will not harm it. You can only charge the battery in the battery charger provided.
