Remember, only a 1/2 to 3/4 of a turn are needed to losen
the screws for the battery door to come loose. And only a
gentle snug should be applied to re-tighten the screws.

NOTE: Please remove the batteries from your headphone amp
if you know your are not going to be using it for more than
a week. All you need is for one of those eight batteries to
go bad and start leaking to make your headphone amp unusable.

In addition, buy a quality name brand of battery like Duracell
or Energizer or even Ray-o-vac, but don't be lured into a cheapo
off brand kind because of the cheaper price, unless you don't
like using your prized Rockman headphone amp.

If you do find that a battery has leaked in your prized Rockman
headphone amp it is important to clean it up immediately as the
leakage can damage the battery contacts beyond repair requiring
them to be replaced. A bad leak can even cause corrosion on
the PCB and electronics components of your prized unit that can
render your headphone amp DOA.

Here’s how to clean up a battery leak.

1. The first thing to do is to choose a well-ventilated area.
In the garage or outside your house is an ideal place to clean
up the leakage since you won't get your ladies knickers in a
twist for stinking up the house or ruining some chair fabric
or carpet with battery acid.

2. Next thing to do is to put rubber gloves and protective eye
wear. Please dont skip this step, Obviously, this is to protect
your hand and eyes from getting battery acid on/in them. Remember
you are working with little battery contact springs, and these
springs tend to flick things, like battery acid, in all directions
when cleaning them.

3. We will now make a cleaning solution for alkaline batteries.

A. Pour 1/2 teaspoon of vinegar or lemon juice into a bowl.
B. Mix in 1 1/2 teaspoons of water.

4. Now its time to clean up the battery leakage. Get a few Q-tip
cotton swabs and slightly dip them in your solution then gently
rub it on the surface of the springs trying not to drip any
solution that could run under the springs and onto the PCB or
components inside. Repeat as necessary to get the corrosion off as
much as possible. Remember easy does it when applying the solution.
You probably won't get all of the corrosion off, but your solution
will neutralize the acid and stop its corrosive effect.

REMEMBER...
Remove the batteries when you know that you will not be using your
unit for more than a week. Change the batteries when they become
weak. AND when buying new batteries, select a good brand of battery.

TIP 1: I use rechargeable batteries in my gear. Yes the initial cash
layout is more, but you will save money in the long run, AND you
will have longer usage/play time due to the fact that rechargeable
batteries have longer power curves before they run out of juice. I
always have a recharged set waiting in my gig bag.

TIP 2: Invest in a small inexpensive ~$3.00 battery checker and check
your batteries often. Like before you play a gig! Usually only weak
batteries will leak unless they have external physical damage.

Rockman ON!
