1. Turn on the Carrier switch
2. Check the following parameters from the Readings, Primary function list:
RF Power : RF Power varies by model:
29–33 watts for the FMX30
95–110 watts for the FMX100
250-275 watts for the FMX250
SWR : Standing wave ratio should be less than 1.1. A reading greater than 1.25 indicates
an antenna mismatch.
ALC : Automatic level control should be between 4.00 and 6.00 volts.
PA DC V : PA DC Volts varies by model, antenna match, power, and frequency.
Typical readings are:
26–30 volts for the FMX30
25–35 volts for the FMX100
37-52 volts for the FMX250
PA DC I : PA DC Amperes varies with model, antenna match, power, and frequency.
Typical readings are:
1.5–2.5 amps for the FMX30
3.04.5–6.5 amps for the FMX100
6.0–8.0 amps for the FMX250
PA Temp : PA Temperature should initially read 20–35 degrees C (room temperature).
After one hour the reading should be 35–50 degrees C. Maximum operating temperature
is 55 degrees C.
PS DC V : Supply DC volts varies by model. It should read 45 volts with the carrier on
and 50 volts with the carrier off for both the FMX30 and FMX100 products. For the
FMX250, the readings should be 65 volts with the carrier on and 75 volts with carrier off.
Voltmeter : This reading should be 0.0.
