Tascam DR-40 Owner's Manual

DR-40 can operate on three AA batteries, or through an 
optional AC adapter (TASCAM PS-P515U) or USB cable 
provided with the unit (USB bus power). 
Alkaline or Ni-MH batteries can be used.

Open the battery compartment cover on the back of the 
unit. Fit three AA batteries to the + and – marks shown in the 
compartment, and close the battery compartment cover.

When using AA batteries, set the type of battery in order to 
accurately show the amount of power remaining and allow 
the unit to accurately determine whether power is available 
for proper operation. (See “Setting the type of AA batteries” on 
page 102.)

Manganese dry cell batteries (R6) cannot be used with this 

• 

unit.
This unit cannot recharge Ni-MH batteries. Use a 

• 

commercially available recharger.
The included alkaline batteries are for confirming operation 

• 

of the unit and might not last very long.
Before putting the bottom battery in, put the ribbon 

• 

inside the compartment first. Failure to do so could make 
removing the batteries difficult.
A great amount of power is required to provide phantom 

• 

power to a condenser microphone. If you use a condenser 
microphone while running the unit on AA batteries (Ni-
MH rechargeable or alkaline), the operation time will be 
greatly shortened because of their low capacities. If you 
need to operate the unit for a long time, use the AC adaptor 
(TASCAM PS-P515U) or the USB cable provided with the 
unit (USB bus power).
