power reduction. This series of events will continue until 20% of TPO is reached, at
which time the DAX transmitter will be faulted off.
If, at some time during the foldback process - but before the DAX is shut down, the
fault condition clears, the transmitter will begin a ramping up process. If the ON, OFF,
RAISE or LOWER buttons are pressed the foldback condition will clear.

Turn DAX On With No RF Power Output
Under certain conditions it may be desirable to turn the DAX on with high voltage on
but no RF power being output. This will allow for a slow ramp-up of power if
necessary.
STEP 1
From either an OFF or ON state, simultaneously press and hold both
RAISE and LOWER buttons for 5 seconds
STEP 2
Turn DAX transmitter ON, if OFF
STEP 3
Slowly ramp power back up with short presses of the RAISE button, as
needed

On-Air PA Module Service
IMPORTANT:
For normal PA module service, it is recommended that the transmitter be temporarily turned OFF before the module is reinserted.
If on-air service is required, follow the on-air module service procedure below to
mitigate risk of secondary transmitter damage (if blown fuses have been replaced with
new fuses but the underlying fault conditions still exist on the PA module, equipment
damage will result as the module is being inserted into a transmitter that is ON).
6.3.5.1
Mod Replacement: Spare PA Mod
DAX-1R and DAX-3: One PA module may be removed temporarily while the
transmitter is on-air. Once the key card is inserted a timer starts, allowing 5 minutes of
DAX operation. After 5 minutes it will be faulted OFF if a module is not reinserted and
the key card removed.
STEP 1
5/2/2013
A simple DC resistance check must be performed on PA modules prior
to insertion into a transmitter while the PA voltage is ON. With an
Ohmmeter, check resistance between the PA fuse, F1, and the drain of
FET (center pin). A slot is provided in the cover of the PA module to
access this point. Ensure resistance is greater than 5k Ohms.
