When necessary, you can enable the SQE test using the Heartbeat switch located
on the Printed Circuit Board (PCB) inside the transceiver body. This must be done
without the tap body installed in the transceiver.
Checking and setting the SQE/Heartbeat switch
1. If the tap body is not installed in the transceiver (for models AT-205 and
AT-206), skip to step 3.
2. To remove the tap body from the transceiver, remove the two panhead
screws and slide the tap body out.
3. Locate the PCB inside the tap body opening. See Figure 1. With the
transceiver facing you, the SQE/Heartbeat switch is on the right side of the
circuit board. Set the switch to the desired setting (“1” = SQE enabled;
“0” = SQE disabled).
4. Install the tap body.
