Deactivating The Signal Functions - Weinmann OXYMAT 3 Servicing And Repair Instructions

The signal patterns for the buzzer consist of 2 identical pulse sequences, repeated every 10 seconds. Each
pulse sequence consists of 5 individual pulses (see Table of Signal Patterns).

6.1.3 Deactivating the signal functions

The signal functions can be deactivated by means of the switches
board. To see where the switches are located on the PCB, consult the illustrations in Section "10.1 Arrange-
ment of the PCBs" on page 76.
