Description of Functions
The transmitter RF Unit comes with an attached RF
antenna. The electric connection to the coding
electronics is done via Dubox connectors.
The radio module works on one of the 32 different
frequencies which are separated into two groups with
16 channels each. The groups are selected via a
soldered connection (J3) and the channels are
selected via the 10-pin Dubox connector and pin
jumpers.
NOTE:
Disconnect all power to the transmitter and
receiver before making any change to the frequency.
Setting the Frequency Channel
The frequency channel of the transmitter must be set to
the frequency channel of the receiver it is going to
control. Each Hetronic radio remote control system is
pre-set at the factory with the correct frequency
channel in the transmitter and receiver. The
frequencies may need to be changed if a transmitter,
receiver, or RF module of either unit has been
replaced. The frequencies of the transmitter and
receiver must be identical.
1. Remove the lower housing from the transmitter.
2. Locate the RF Module inside the transmitter.
3. Locate the Frequency Channel Jumper Block on
the RF module (shown below).
4. Find the correct chart for your RF Module (CS
458, CS 447, CS 434 or CS 402)
5. Set the frequency jumpers on D0, D1, D2, or D3
according to the chart.
• "ON" means that a jumper should be placed in
that position.
• "OFF" means that the position should be empty.
6. When finished, reinstall the lower housing onto
the transmitter.
The following diagrams show the transmitter RF
module, each channel/frequency and the positions of
the jumpers.
