LED is normally on and will switch off when the level exceeds 100 Set the volume of the radio connected to the ADS SR1 so that the green LED flickers in response to your voice without the red LED dimming noticeably Setting the transmit audio level is a two step process First the range can be set roughly using DIP switches 1 and 2 The audio level will be lowest with both switches off and highest with both switches on When set properly the transmitted audio should sound natural and not distorted or clipped without being excessively quiet The 98 command will cause the unit to transmit a 1 kHz tone at full amplitude for several seconds to help with adjustment If you can t find a combination of DIP switch settings that yields a comfortable audio level it can be further adjusted using a DTMF command detailed below Operation When repeater mode is enabled as it is by default the ADS SRI listens for activity and automatically starts recording when audio is detected If the red light does not come on in response to radio activity check that the volume level of the radio is set correctly A period of silence initially set to two seconds tells the ADS SR1 that the transmission is finished and it then keys the radio and retransmits the message Many mobile radios provide a squelch COR COS or busy signal that can be used with the ADS SR1 s squelch input This allows the VOX delay to be eliminated See the sectio
