4. Set the gain for -25 to +25 dB on each channel for a maximum output level of +10 dBm for each
channel. (See Section 2.5 Menu Settings).
5. Be sure DS6 (green, DC Power) is on and DS2 (red, Alarm) is off (Figure 2.3).
6. To insure that CH1 and CH2 amplifiers are not being overloaded check that CH1 PEAK and CH2
PEAK LEDs, DS3 and DS1, are off (Figure 2.3).
7. AC Fuse - The fuse is a 5 mm X 20 mm, 2 amp slow blow (Type T) and is inserted in the far slot in the
drawer below the AC input as shown in Figure 2.4. There is a spare fuse in the near slot. If a fuse
continues to open, the power supply is most likely defective.
