1.3.0 HOW TO ACTIVATE THE AU9 WHEN IT IS ARMED-READY
To start full power transmission the following operations have to take place:
1.3.1 When the unit is ARMED the user firmly presses the round rubber button on the front of the unit
(no 10). The unit will now transmit continuously until switched off by moving the side Arming Switch
(no. 11) UP until it positively clicks.

1.3.2 Alternatively for automatic activation the user enters the water, after 5 seconds of continuous
immersion the unit will self activate and transmit continuously until switched off by moving the side
Arming Switch (no. 11) UP until it clicks, the unit will ‘BEEP’ and stop transmitting after a few seconds.

NOTE – The unit has two waterpin sensors, (no. 3 & 9), both these sensors have to be continuously
immersed for a period of not less than 5 seconds to allow the unit to wake up and auto-activate, this
prevents inadvertent activation by spray, rain, splash.
