v WARNING:
Set the transceiver output power and linear ampli-
fier ALC output level referring to the linear amplifier
instruction manual.
The ALC input level must be in the range 0 V to –4
V, and the transceiver does not accept positive
voltage. Non-matched ALC and RF power settings
could cause a fire or ruin the linear amplifier.
☞ NOTE: The specifications for the SEND relay are
16 V DC/2 A. If this level is exceeded, a large ex-
