Page 21: Advanced Muting Function
Advanced muting function This receiver also features AMF (Advanced Muting Function). This special electronic feature comes into effect when an RF signal drops by about 40 dB in a short time. The reception is then muted for at least three seconds. AMF thus suppresses the annoying switch-off click when a transmitter is switched off. -
Page 22: Automatic Transmitter Search Tuning - Scan Function
Automatic transmitter search tuning – Scan function The EM 3532 receiver features a scan function to scan the frequency range of the tuner for a transmitter. For some countries, this menu is locked via a special configuration program, since not all tunable receiving frequencies are approved in these countries. - Page 23 If no transmitter is found, the search tuning stops at the upper or lower limit of the 24 MHz frequency window. The display then indicates: If a transmitter with a strong enough RF signal (higher than the squelch level, but at least 5 μV) is found, this frequency is indicated on the display.
