Vehicular Repeater This manual is intended for use by qualified technicians and includes all necessary information pertaining to the SVR-200 operation, circuit design and maintenance. Changes that occur after date of printing will be incorporated in supplemental service publications. RF Exposure W arning: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
Do not operate the SVR-200 while refueling the vehicle or in the presence of explosive fumes. • Do not operate the SVR-200 with persons standing closer than 2 feet from the mobile or repeater antenna. FCC information The SVR-200 complies with the FCC rules parts 90 and 22 for radio frequency transmitters. The user must apply for a license to operate the SVR-200 transmitter pursuant to parts 90.243 and 90.247.
The SVR-200 has a fixed 3 minute time out timer for base to handheld transmissions. If the mobile COR is active for more than 3 minutes (and the SVR-200 is the priority unit) it will send a double blip and cease transmission until the mobile COR is inactive.
The user then keys their handheld to speak on the voice channel. If the user does not key up within the 2 second period, the SVR-200 will unkey the mobile and send intercept tone as before.
J3 Used for testing the SVR-200 receiver and setting the lock tone deviation transmit level. If JP3 is shorted at power up, the SVR-200 receiver will be active all of the time and receiver audio will be heard at the speaker regardless of the repeater squelch setting or CTCSS tone decoded.

COR line as active low. The input from pin 7 is high impedance and does not have to go rail to rail. The SVR-200 uses a voltage comparator as a COR threshold detector. RV1 sets the mobile COR threshold level and should be set for half way between the mute and unmute levels at pin 7.
