TYPE OF BATTERIES TO USE - Pocket Amp 2 operates on two
rechargeable (1.2 Volt) AA sized batteries.You may use the Nickel
Cadmium (Ni-CAD) type, and they will work great. However, it is
recomended that Nickel Metal Hydride (NiMH) rechargeable batteries
are used if possible. Their higher energy capacity, and lack of memory
effect will result in longer operation times. Here is a great page
discussing more about the differences.

INSTALLING THE BATTERIES - The batteries should always be
installed, even if the amp is used with the AC adapter. To install the
batteries, simply remove the two screws located on the back of the
amplifier. You will need a small Phillips or "star" screwdriver to do this.
Turn the screws counterclockwise to remove them. Remove the amp's
lid and install the batteries, observing the polarity. After the batteries are
installed, replace the lid and be careful not to over tighten the screws.
Just a snug feel is fine.

RECHARGING THE BATTERIES - Once the batteries are
installed inside Pocket Amp 2, you will not have to open the amp up for
about 500 to 1000 recharging cycles, which should easily amount to
three or four years of normal use. Pocket Amp 2 has a built in
recharging circuit. When the AC adpater is plugged in, the batteries will
automaticaly begin to recharge, whether the amplifier is in the ON or
OFF position. If the AC adapter is connected, and the amp is ON and
being used, the batteries will not be overcharged. However, if the
amplifier is OFF, the AC adapter should not be plugged in for periods
longer than eight hours to avoid overcharging.

THE AC ADAPTER - The main purpose of the AC adapter is to recharge the
batteries inside the amplifier, and to power the amp when being used from an AC
source.
There are many different AC power systems around the world. If you ordered an
amplifier which did not include the 110 volt AC adapter the good news is that any
adapter with the following features can also be used:
Output Voltage: 3 Volts DC
Output Current: 200 Milliamps or greater
Plug Size: A 2.5mm male mono plug with a Negative Tip polarity.
A universal adapter such as the one pictured on the right, may also be used.

USING THE AMPLIFIER - Instead of
plugging your headphones directly into the source
device, you can now plug your headphones into
Pocket Amp 2's output jack (#6). Next, a
connection cord is used to feed the audio device's
output into Pocket Amp 2's input jack (#5).

Most portable music devices will have a 3.5mm (1/8") "mini" headphone jack. In this case, a 3.5mm (1/8") male-to-male cord
(sometimes called a "Patch Cord") is needed for the connection. If your music device has RCA outputs, then an RCA to
3.5mm (1/8") adapter would be needed. After your source device has been connected, It is best to set the volume level on
your source device to about 60% of the maximum level, but since each device is different, you may experiment to find the
setting you feel is the best. Use the volume knob on Pocket Amp 2 to control the sound level to your headphones.

VOLUME KNOB - The amp's volume knob is not permanently glued on so during shipment (or your own use) it may
somehow become stumped down. This can cause the knob to rub against a nut below with friction instead of rotating smoothly.
If this happens the knob can be gently pried back up from underneath with the help of a thin coin.
