MAINTENANCE

WARNING

The following instructions are for use by qualified personnel only. To avoid electrical shock, do not perform any servicing other than contained in the operating instructions unless you are qualified to do so.

FUSE REPLACEMENT

If the fuse blows, the LED indicator will not light and the power supply will not operate. The fuse should not normally open unless a problem has developed in the unit. Try to determine and correct the cause of the blown fuse, then replace only with a fuse of the correct rating. For 110 or 120V operation a 1.6A, 250 V, 3AG fuse should be used and for 220 or 240V operation a 0.75A, 250V, 3AG fuse should be used. The fuse is located on the rear panel (see Fig. 2).
