3.9 Test Cable
The alignment procedure is optimized through the use of the provided test cable. This
test cable is designed for use with a digital voltmeter (not provided) to read the Link
Quality and Receive Signal Level (RSL) voltage generated by the radio’s receiver.
1. To read the RSL value of the radio, insert GND (ground) and RSL banana plugs
into the voltmeter. Note the RSL voltage. The voltage may be fluctuating; in this
case, note the maximum value seen.
