TASCAM DR-40 25Powering the unitDR-40 can operate on three AA batteries, or through anoptional AC adapter (TASCAM PS-P515U) or USB cableprovided with the unit (USB bus power).Alkaline or Ni-MH batteries can be used.Using AA batteriesOpen the battery compartment cover on the back of theunit. Fit three AA batteries to the + and – marks shown in thecompartment, and close the battery compartment cover.When using AA batteries, set the type of battery in order toaccurately show the amount of power remaining and allowthe unit to accurately determine whether power is availablefor proper operation. (See “Setting the type of AA batteries” onpage 99.)NOTE• Manganese dry cell batteries (R6) cannot be used with thisunit.• This unit cannot recharge Ni-MH batteries. Use acommercially available recharger.• The included alkaline batteries are for confirming operationof the unit and might not last very long.• Before putting the bottom battery in, put the ribboninside the compartment first. Failure to do so could makeremoving the batteries difficult.• A great amount of power is required to provide phantompower to a condenser microphone. If you use a condensermicrophone while running the unit on AA batteries (Ni-MH rechargeable or alkaline), the operation time will begreatly shortened because of their low capacities. If youneed to operate the unit for a long time, use the AC adaptor(TASCAM PS-P515U) or the USB cable provided with theunit (USB bus power).3 – Preparation
