Trouble Shooting
AS608/AS608e does not turn on:
Using External Power Supply:
The power cable must be correctly connected to the mains.
The mains switch must be "on", and the power switch on
the external power supply must also be "on".
If still nothing happens a fuse in the external power supply
may be blown. Replace fuses with exactly the same type.
Using Batteries:
The batteries might need to be changed - an indication on
the top right corner of the display will be provided and the
operator prompted on the status via a flashing screen.
External Power Cable connected to AS608/AS608e will
disconnect batteries - unplug cable for battery operation.
No tones in the DD45 headphone:
Left (F1) or Right (F2) ear must be selected.
The Attenuator (2) must be turned up.
The “Tone” presentation signal
(A) must be activated by
touching the Tone Switch.
If still no sound appears check that the headphone is
correctly connected to the “phone” outputs.
