Following are step-by-step instructions for changing the mains voltage of the MPL 1640.

WARNING: Before carrying out this operation, remove the power cord!

110

110 220

1:Insert a small screwdriv- er into the hook beneath the fuse sled and pull it out from its retaining clip. Hold the hook with your fingers and gently pull the sled out.

2: Remove fuse sled.

3: Use a small pair of needlenose pliers to gently pull out the mains jumper.

110	220
220	110

4:Use the needlenose pliers to turn the mains jumper upside down so that the other voltage value is right side up, then reinsert the mains jumper. Reinsert the fuse sled by gently pushing it back in until you hear a click and snap the hook back beneath its retaining clip.

Note that the fuse sled carries two fuses—one for 115 volt operation (actually 105 - 120 volts) and another for 230 volt operation (actually 220 - 240 volts). The position of the two fuses in the sled as well as the fuse ratings must be maintained for adequate protection. Fuse ratings for the MPL 1640 are: 1 amp for 115 VAC and .5 amp for 230 VAC.
