I don't doubt this has been addressed before, but I can't seem to locate the topic in a search.  My apologies if this is repeating a topic.  The manual for the multifunction head seems to have ass-backwards instructions regarding the use of an external power supply.

As shown in the picture below, the manual identifies the upper hole as Aux Power and the lower as DC Power.

 
It says Aux is to power other devices and DC power is the place to put external power from a battery or a AC adapter.  It gives a very grave warning (beside a bomb with a lit fuse!) to NEVER plug external power into Aux or the batteries may go BOOM.  So, the instructions are clearly telling me to put any external power into the LOWER hole.

However, on my head, the upper hole is labeled IN and the lower OUT.  If I look at the downloadable manual for the newer GOTO version of the head, the photo in it shows the holes labeled the same as mine and even points them out as DC IN and DC OUT.  See below. 


The GOTO mount's manual goes on to say:

If you are using a portable battery like the Orion Dynamo
Pro, use the Dynamo’s supplied 12V DC power cable (cigarette
lighter plug on one end, standard 12V DC power plug
on the other end) to connect the battery to the 12V “DC IN”
(Figure 4b) power jack on the side of the mount. Make sure
the Dynamo’s power switch is in the “off” position when connecting
cables. Power the TeleTrack AZ-G on by pressing the
red on/off switch to the “on” position
AC Adapter
In addition, the mount can be powered by an optional AC
adapter rated at 12V DC, 1000mA, tip positive. Plug the adapter
cord into the “DC IN” power jack for operation. Power the
TeleTrack AZ-G on by pressing the red on/off switch to the “on”
position.
Power Output
Unlike many mounts in its class, the TeleTrack AZ-G Mount
will provide power output for accessories like digital cameras
or camcorders. It accepts a DC power plug (tip positive) and
provides 12V DC power output. To power a 12V accessory
with the TeleTrack AZ-G, simply plug the accessory’s 12V DC
power cable into the “DC OUT” (Figure 4b) jack on the side of
the mount.
Caution: Never plug an external power supply cord into
the “12V DC OUT” jack accidentally. This may damage the
AA batteries inside the battery compartment, and possibly
damage the mount itself.

This is exactly the opposite of what is in the manual that came with my head.

Should I believe the manual that came with my head?  Or should I believe my common sense, which matches up with the description in the OTHER head's manual?  If the manual is that FUBAR about something that can potentially KILL the head, can i believe anything else it says??
