HOW TO REDUCE RANGE
To reduce the receive range, set the RSSI jumper to
ON
and adjust
VR1
to
the required reduced range. The procedure is as follows:
1.
Adjust VR1 position to the point where the LED1 just turns off.
NOTE
: To aid in this adjustment the SFR-200 Receiver's audible beep
can be used. Each time a Cansec SmartFob transmitter is decoded
correctly the SFR-200 receiver will beep.
2.
Adjust VR1 toward the (
-
) or reduced range.
3.
Back away from the receiver and press the SmartFob transmitter. If no
audible beep is heard, the range has been exceeded.
4.
Repeat this procedure until the required range is found.
NOTE
: It is important to test more than one SmartFob transmitter to verify
this reduced range. It is also important to test the area of reception from all
different angles to the SFR-200 receiver.
