2. Check and clean the fans regularly to ensure that they always operate properly.
3. Clean the touchscreen as follows:
a) Apply a small amount of standard screen cleaner to a soft cloth.
b) Wipe the screen gently with the moist, but not wet, cloth.
c) If necessary, remove any excess moisture with a dry, soft cloth.
16.2 Storing and Packing
The storage temperature range of the instrument is given in the data sheet. If the
instrument is to be stored for a longer period of time, it must be protected against dust.
Repack the instrument as it was originally packed when transporting or shipping. The
two protective foam plastic parts prevent the control elements and connectors from
being damaged. The antistatic packing foil avoids any undesired electrostatic charging
to occur.
If you do not use the original packaging, use a sturdy cardboard box of suitable size
and provide for sufficient padding to prevent the instrument from slipping inside the
package. Wrap antistatic packing foil around the instrument to protect it from electro-
static charging.
16.3 Replacing the Fuses
The instrument is protected by a fuse. You can find it on the rear panel between the
main power switch and AC power supply.
Type of fuse: Size 5x20 mm, 250V~, T2.5H (slow-blow), IEC60127-2/5
Risk of electric shock
The fuse is part of the main power supply. Therefore, handling the fuse while power is
on can lead to electric shock. Before opening the fuse holder, make sure that the
instrument is switched off and disconnected from all power supplies.
Always use fuses supplied by Rohde & Schwarz as spare parts, or fuses of the same
type and rating.
1. Pull the fuse holder out of its slot on the rear panel.
2. Exchange the fuse.
3. Insert the fuse holder carefully back in its slot until it latches.
