and used in accordance with the instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off and on, the user
is encouraged to try to correct the interference's by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected
• Consult the dealer or an experienced radio/TV technician for help.
Changes or modications not expressly approved by Sauermann could voice the user’s authority to operate the
equipment.
This device complies with part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference received, including interference that may cause undesired operation.
2.2 Canadian standard
This device contains licence-exempt transmitter(s)/receiver(s) that comply with innovation, Science and Economic
Development Canada’s licence-exempt RSS(s). Operation is subject to the following two conditions:

Trend indicator:Trend indicator: on the screen, a trend indicator represented by a rising arrow, a going down arrow or a stable ar-
row is displayed on the left of the measurement unit. It means the calculation of a moving average on the last hour
(M1) to compare with a moving average on the last 5 minutes (M2):
• If M1 = M2, the trend is stable.
• If M1 < M2, the trend is upwards.
• If M1 > M2, the trend is downward.
This trend indicator is displayed after 5 minutes.
Alarm pictogram: on the screen, an alarm pictogram is displayed for each channel. Two different pictograms can
be displayed:

Mounting 9
4. Mounting
The transmitter must be mounted before any wire connections.
The transmitter must not be powered before mounting it.
To install the transmitter on a wall:
• Fix the stainless steel plate to the wall (drilling: Ø 8 mm, screws and wall-plugs supplied).
• Insert the transmitter on the plate (see A on the drawing below) by aligning it at 30°.
• Rotate the housing in clockwise direction until you heard a “click” which conrms that the transmitter is cor-
rectly installed.
• Open the housing, lock the clamping system of the housing on the plate with the screw (see photo below).
The xing screw is in a plastic bag into the box of the C320. type of screw: Cruciform screw Ø 3.5x12 mm
