Q What is Listen Technologies product warranty?
A Click for Listen's product warranty.
Q How long do we need to charge the rechargeable batteries when we first get them?
A Charge the batteries two full cycles (13 hours each) before use.
Q Does Listen offer case for more than 16 units?
A Yes. There is a configurable case (LA-320) for up to 20 units. This case does not have charging capabilities.
Q Can you ship the case without packaging it up
A No, shipping cases without external packaging, the cases can be easily damaged and equipment lost. Always use additional packaging when shipping cases.
Q Will a LA-311 fit into a standard 19" rack drawer?
A The LA-311 16 unit charge/carry case width is too wide to fit in a standard 19 inch rack drawer. The 18.5" dimension is wider than the inside of the mounting rails on a standard 19" rack. However, It will fit on a wide rack shelf such as a WUSS series from Middle Atlantic if there are no rails and an open space is above the shelf ( 4 total rack units) or alternatively on a deep shelf and the LA-311 is placed in sideways.
Q Do the earpieces fit into the case?
A Not all the earpieces fit. The ear buds and the ear speakers will fit nicely.
