Replacing the battery
If the standby LED (4) and the LED (6) in the tip of the receiver (contact-free voltage display)
flash simultaneously, the battery voltage is in a critical state.
If the battery voltage of the receiver is too low, the standby LED (4) will not illuminate.
In both cases, replace the 9 V block battery.
To this end, open the battery compartment (5) by pulling down the cover (see arrow symbol on
the cover).
