The AXC25/35 comes with the Auto Power Down feature enabled to save energy and extend the life of the unit by powering down automatically whilst not in use.
You can enable or disable the unit's APD setting by pressing and holding the Power button until the LED flashes in sequence.
The two options below show which option is selected:
Standby flashes 5 times - APD disabled
Standby flashes 10 times - APD enabled
Please note: Make sure the unit is On, before attempting to make changes to the APD function.
