1. Turn the 504 II over and open
the cover of the battery
compartment on the bottom.
Press the latch to release it and
then raise the cover.
2. Insert four fresh IEC R6
(size AA) batteries into the
battery compartment.
3. Close the cover of the battery compartment.
Close the cover of the battery compartment.
Push the cover in until the latch audibly snaps into place.

Using
the
unit
on
batteries
Use four IEC R6 (size AA) batteries.
When the batteries are getting low, a dot (.) in the bottom section of the
display starts to flash.
NOTE
While not using the 504 II, you should disconnect the cable plugged
into the INPUT jack, to prevent draining the batteries.
Play mode/edit mode
The internal status of the 504 II is referred to as the operation mode. The
two major modes are play mode, in which you can select patches and use
them for playing your instrument, and edit mode, in which you can modify
the effects. The [PLAY/EDIT] selector serves for switching between the
play mode and edit mode.
Global parameters
Normally, effect parameter settings are stored individually for each patch,
but some effect parameters affect all patches. Such parameters are called
global parameters. The global parameter settings do not change also when
the patch is switched.
This section explains some important terms that are used throughout the
504 II documentation.
Effect parameter
The effects of the 504 II consist of a succession of modules that determine
the sound. These individual modules are called the effect parameters. As
shown in the following illustration, the 504 II has 10 different effect
parameters. Changing the setting of an effect parameter is like turning the
control knob on a compact effect, leading to a change in the sound.
Effect type
Some effect parameters comprise several different effects which are
referred to as effect types. For example, the DLY&REV parameter has the
four effect types LARGE, SMALL, DELAY, and DLY+REV. Only one of
these can be selected at a time.
Patch
In the 504 II, effects are stored and called up in units referred to as patches.
A patch comprises information about the setting and on/off status of effect
parameters. The memory of the 504 II holds up to 36 patches.
Bank
A group of six patches is called a bank. The 504 II manages a total of six
banks, labelled A through F. The patches within each bank are numbered 1
through 6. To specify a patch, the 504 II uses the following format: "A1".
This means that patch number 1 from bank A is selected. Therefore "b6"
would refer to patch 6 from bank b.
