Storing Patches
If you have edited (altered) a patch and turn the 508 off without storing the patch, the patch will revert to its old setting. To store an edited patch, use the following simple procedure.
Storing can be carried out in both Play mode and Edit mode. After you have edited the patch, press the STORE key. If the unit is currently in Play mode, release the key before 1 second has elapsed, otherwise the Direct Load function will be activated.
The display starts to flash. This condition is called the store standby condition. If you wish, you can abandon the store procedure at this point by pressing the EDIT key. If you press the STORE key once more, the contents of the patch are updated.
You can also change the patch number before storing, so that the edited patch will be stored in a different number.
In this case, the original patch that was used as a starting point for editing will not be changed.
(2) Press the STORE key. | (4) Press the STORE key once more. |
(Unit enters store standby mode.) | (Store process is completed.) |
A 1 | A 1 | b 4 | b 4 | b 4 |
(1) Edit the patch as desired. | (3) Select the patch for storing. |

Replacing the Battery
If the tuning indicator flashes while the unit is being powered from the battery, the battery is exhausted and should be replaced as described below.
Since the 508 has fairly high rated power consumption, use only a 6LR61 9 V (alkaline) battery. Using another kind of battery will result in shorter operation.
Cover
6LR61 9 V (alkaline) battery
Cable
1.Turn the 508 upside down and open the cover of the battery compartment. (Push the catch to unlock the cover, then lift it up.)
2.Remove the battery from the compartment and disconnect the battery cable. (Grasp the terminal strip and do not pull at the cable.)
3.Connect the battery cable to the new battery, taking care to observe correct polarity
4.Close the battery compartment cover, taking care not to pinch the cable. (Make sure that the cover is properly locked.)

Returning Patches to Factory Settings
The 508 comes with 24 predefined patches that have been programmed at the factory. Also after you have edited and stored your own patches, you can return to the factory default settings at any time. This process is called "recalling". Returning all 24 patches to the original contents and resetting the Bank Hold and Direct Load functions is called "all initialize".
The Recall mode is separate from the Play mode and Edit mode. You cannot switch directly to Recall mode from these modes. The Recall mode can only be activated by turning the unit on in a special way, as described below.
1.Turn the unit off by disconnecting the AC adapter or the guitar input cable.2.Keep the STORE key depressed and turn the unit on.3.The indication "AL" flashes on the display.4.To perform "all initialize", press the STORE key once more in this condition. The flashing rate increases and the initialization procedure is carried out. When it is completed, the unit automatically enters the Play mode.
5.When wishing to recall only a particular patch, select the patch number in step 3, using the same procedure as for normal patch selection.
6.When the desired patch has been selected, press the STORE key. The flashing rate increases and the contents of the selected patch are recalled.
7.Recalling of individual patches can be carried out continuously. When you wish to terminate the process, press the EDIT key. The unit then returns to the Play mode. Turning the unit off also terminates the recall condition.
