Batteries
The DR-T40 and DR-T45 require 2 AA size batteries.
• DR-T40 Handheld Transmitter: Turn clockwise until
loose and slide down, exposing the battery holder.
Insert 2 fresh AA batteries according to the correct
polarity (indicated on the transmitter body). Screw
the battery cover back onto the microphone, making
sure it is securely tightened.
• DR-T45 Body Pack Transmitter: Open the battery
compartment cover by gently pressing the two latches
centered on the side of the unit, and gently pull the
latching door open. Insert the batteries, noting that
+terminal aligns with the metal tab, and the –terminal
aligns with the spring.
Fresh alkaline batteries can last up to 8–10 hours
of operation. To ensure optimum performance, we
recommend you replace batteries after 6–8 hours of
use. The battery meter has 5 bars to indicate battery
strength. As the batteries weaken, fewer bars will show
until the BATT icon begins to flash. To preserve battery
life, turn the transmitter off when not in use.
