Line Cord and Fuse Warnings
13. The AC line cord is removable. Use a grounded 3-prong line cord that is appropriate for your
region. Your dealer can provide you with the correct line cord.
14. Do not defeat the purpose of the grounded power plug. The ground prong is provided for your
safety. When a 3-prong outlet is not available, please consult an electrician for replacement of
the obsolete outlet. Do not use 2-prong to 3-prong adapters. Do not attempt to solve AC hum
problems by lifting the AC safety ground!
15. Unplug this apparatus during lightning storms or when unused for long periods of time.
16. This apparatus is equipped with an auto-ranging power supply. There is no internal voltage
selection switch - do not attempt to open the unit. Operating voltage ranges are 100 to 120 Vac
+/- 10%, and 220 to 240 Vac +/- 10%. Operating frequency is 50 to 60 Hz. All operating
voltages use the same fuse size.
17. For continued fire and shock protection always replace the fuses with the correct size and type
(T 8A H 250V, 5x20mm), (T = time lag, 8A = eight Amps, H = high breaking capacity, 250V =
voltage rating, 5x20mm = cartridge size). High-breaking fuses use a ceramic body. Use Bel
Fuse 5HT 8-R, or Schurter 0001.2513, or an exact equivalent. The fuse drawer includes two
fuses. Always replace both fuses at the same time.
