Common 3000 / 5000 Series (EM 3732 / SR 3254 / SKM 5200 / EM 3532) errors & problems

AF Peak warning on EM 3732 / distorted audio
Likely cause: Overmodulation clips in the transmitter before RF; receiver output level only fixes distortion downstream of the RF link.
- Step-by-step fixGet the fix →
check frequency on SKM 5200 without transmitting
Likely cause: Lets you verify/change channel mid-show without blasting RF on a wrong frequency.
- Step-by-step fixGet the fix →
daisy chain antennas between 3732 receivers
Likely cause: The integrated splitter is unity gain (0 dB ±0.5 dB) so chained units share one antenna pair without extra loss.
- Step-by-step fixGet the fix →
EM 3732 shows MUTE and red LED, no audio
Likely cause: The receiver mutes audio whenever RF on both diversity branches is under the squelch threshold, so a too-high squelch or a dead path gives silence even with a live transmitter.
- Step-by-step fixGet the fix →
intermod in big multichannel 5000 series rig
Likely cause: LoI mode is designed for high intermod immunity in dense multichannel use.
- Step-by-step fixGet the fix →
IR sync not working SKM 5200 to EM 3732
Likely cause: IR sync only transfers settings between matched range variants on the HiDyn plus (HDP) compander path.
- Step-by-step fixGet the fix →
no RF on EM 3732 with active antennas / booster LED off
Likely cause: Active antennas need DC on the coax; a shorted cable or connector drops the booster and kills gain on that branch.
- Step-by-step fixGet the fix →
SKM 5200 battery life short / low batt
Likely cause: RF power setting roughly halves runtime between 10 mW and 50 mW.
- Step-by-step fixGet the fix →
SKM 5200 won't turn off / buttons not working
Likely cause: Autolock is a designed anti-tamper feature, not a fault.
- Step-by-step fixGet the fix →
wireless mic noisy / hiss, low level
Likely cause: Under-modulating the link raises the relative noise floor of the compander system; correct gain staging at the transmitter gives full SNR (typ.
