Sennheiser 3000 series Instruction Manual page 5

To open the battery cover you must squeeze the catches on
either side and move towards the hinge, as shown by the
small arrows on the diagram, on the left.
When they have reached the end of their travel you can
hinge the cover open. This gives access to change the battery
set of 2 x MN2400 (AAA). Please check for polarity when
inserting.
Open this cover to give access to the controls etc as below.
Close the cover when you have finished. It will close with a
click as the catches engage. This arrangement prevents
accidental access to the controls, but the LED (2) is still
visible.

When the On/Off switch (6) is moved to the ON position, the LED (2) lights. The LED
will start to blink about 30 mins before operation will cease. The rate of blinking will
increase as the battery life diminshes.
Screwdriver switch (4) is used to adjust the input gain. We test at a setting of 3, and
find this level suits most applications. If the input is overloaded the LED (2) will flash
brightly.
This is a particularly small transmitter, with a case size of 53 x 60 x 17 mm.
