Take a spare radio receiver from case 13 | Spare pack and connect it. Make sure the cables of the radio receiver are connected correctly as shown in
the diagram below and wait for the radio receiver to connect. It may take up to 5 minutes for the radio receiver to start up.

Go to the Maintenance tab and turn off the radio receiver that has been removed from the system and turn on the deployed spare radio receiver.
Please contact local supplier for instructions.

Re-measure the system according to the instructions in Training Field Survey. The radio receivers must be measured in numerical order. E.g. spare radio
receiver 10 replaces radio receiver 2, then measurements are taken in the following order: 1-3-4-5-6-7-8-10.
