Inserting/Replacing The Batteries - Conrad Electronic Soundlevel-Calibrator 326 Bedienungsanleitung

Inserting/replacing the batteries

1. Carry out the following quick test in order to make sure that the
device works properly and that the battery is not exhausted:
Set the selector switch in position 114 dB. If the device works
properly, you can hear a 1000-Hz whistle and the LED lights
green (Power ON). If there is no whistle to be heard and the LED
lights red (Low Battery), replace the batteries.
2. Open the battery compartment on the back of the device by
means of an appropriate slotted screwdriver, click a new 9V block
battery (alkaline) onto the battery clip and close the battery
compartment. Always ensure correct polarity of the battery.
Wrong polarity might destroy the sound level calibrator. Carry out
the quick test again.
