RP250GDS Only:
The audio should remain as white noise.
If the signal is higher, this indicates that interference may be present.
Interference can be generated by nearby electronic equipment. If the
interference is from a nearby telemetry system then an alternative frequency
for the final installation may be necessary.
Should interference be detected and the origin cannot be found then
advanced interference detection equipment will have to be used, e.g a radio
frequency spectrum analyser. Refer to Eltek.
Before installation a survey should be conducted.

Preparing the transmitter and repeater for the survey
10.5.1
Prepare the transmitter
Set the transmitter's transmit interval to 1 second:
-
Connect the survey transmitter to the PC with the cable supplied.
-
In RxConfig, open Transmitter Setup
-
Enter the correct COM port and click OK / Connect.
-
Enter 1 second as the Tx Interval and click Set Tx Interval.
10.5.2
Prepare the repeater
-
Ensure the battery in the RP250GD/RP250GDS is fully charged. From
fully drained, the battery takes 3-4 days to charge.
-
Power on the repeater by briefly connecting the mains supply or by
using the concealed button on the back.
-
When a valid transmitter signal is received by the
RP250GD/RP250GDS repeater, the transmitter serial number and RSSI
(signal strength) will be displayed on the repeater's LCD display.
-
If using an RP250GDS, the loudspeaker audio will be change from
white noise to a short bark or croak. If the signal is strong the bark is
clean and as the signal weakens the bark will become dominated by
the white noise.
