What would cause a 7-Level Communication Builder to be inconsistent in the play back mode, playing only a portion of the message or not playing the message at all?
Most likely the problem is caused by weak or rechargeable batteries. We recommend a good alkaline battery like Duracell or Energizer. Rechargeable batteries are inappropriate for use because they do not provide enough power to run the units. Also, do not mix batteries from different manufacturers. A new set of alkaline batteries should solve the problem. Under normal daily use, you should get 3 to 4 weeks use from a new set of batteries.
