CONFIGURATION
4.1 Introduction
The radio is commonly configured to parameters provided by the cus-
tomer at the time the order was placed. Even so, there are some param-

steps summarize the initial set-up of a LEDR radio link. If this is your
first installation of a LEDR radio system, it is recommended the equip-
ment be set up on a test bench.
4.2 STEP 1—Power up the LEDR Radios

the unit will start the radio operating. After a short self-test, a “default

NOTE:
The LEDR radio is normally keyed continuously, and the radio
will transmit whenever power is applied. Ensure there is a suit-
able load on the antenna connector before connecting power.
