Try changing the feed horn position (forward/back) and polarisation (angle of the
receiver in the holder) to increase the pointer defl ection as well.
Repeat this procedure until no signal improvement is possible anymore. Attach all setting screws
of the receiver system reliably.
After successful setting, switch off the entire system, remove the connection cable and the sat
fi nder and connect the cable from the satellite receiver to the receiver unit. When connecting
the cables, ensure suffi cient weather and moisture protection. Ingressing water oxidises the
contacts, which may cause system failure sooner or later!

11. MAINTENANCE AND CLEANING

a) General Information
To ensure accuracy of the multimeter over an extended period of time, it should be calibrated
once a year.
Notes on replacing the battery are provided below.
Regularly check the technical safety of the device and measuring lines, e.g. check for
damage to the casing or squeezing, etc.
b) Cleaning
Always observe the following safety information before cleaning the device:
Live components may be exposed if covers are opened or parts are removed
(unless this can be done without tools).
The connected lines must be disconnected from all measuring objects before the device is
cleaned or repaired.
Do not use any carbon-containing cleaning agents or petrol, alcohol or the like to clean the
product. They will damage the surface of the meter. Furthermore, the fumes are hazardous to
your health and explosive. Also do not use any sharp-edged tools, screwdrivers, metal brushes,
etc. for cleaning.
Use a clean, lint-free, antistatic, dry cloth for cleaning the device or the display and the measur-
ing lines.
