This function is for changing the tones and beacon 
settings for the MX Symphoni sounders and AVBase 
devices. The function will be greyed out on the Test 
Functions menu unless a supported MX device is 
connected.
On the main change tones screen that appears as shown 
in Figure 25, 1Hz and ½ Hz options are for changing the 
ash rate of the built-in beacon. VOL LOW and VOL 
HIGH change the volume of the tone. RESET will reset 
the settings back to the factory default. The current 
settings are highlighted in green.

Pressing TONES will bring up another screen shown 
in Figure 26 that allows the particular tone type to be 
selected. Temp 3 (Temporal 3) is the standards compliant 
tone for Australia.

For sensors that aren’t present in the MX device or don’t 
support self test, N/A will be shown as the value for that 
sensor. Many detectors support self test on only one of 
their sensors, and some don’t support self test on any 
sensors at all.
Entering the SELF TEST function performs a self test of 
the supported sensors of a detector.
Initially PLEASE WAIT… will show on screen, then the 
results will appear as shown in Figure 24. The overall 
result of the self test across all supported sensors will 
be shown at the bottom of the screen – in this case, 
PASSED.
