calibration mode.
Press and hold the [LOW] button, and then press the [LOW] button.
2) Full
The RF signal generator turned to the same frequency, set the generator for +/-3.5 kHz deviation with
1kHz tone modulation,and set the output level for +20dBu at the antenna jack.
Press and hold the [LOW] button, and then press the [LOW] button.
Squelch Threshold Calibration
The RF signal generator turned to 146.100MHz, set the generator for +/-3.5 kHz deviation with 1kHz
tone modulation,and set the output level for –15dBu at the antenna jack.
Tune the dail knob and select [SQL], then press the [MHz] key. The radio now is in the squelch
calibration mode.
1) Threshold
Press and hold the [LOW] button, and then press the [LOW] button.
2) Tight
The RF signal generator turned to the same frequency, set the generator for +/-3.5 kHz deviation with
1kHz tone modulation,and set the output level for -4dBu at the antenna jack.
Press and hold the [LOW] button, and then press the [LOW] button.
Sensitivity
Tune the dail knob and select [RX TUN], then press the [MHz] key. The radio now is in the squelch
calibration mode.
Adjust the dail knob for optimum SINAD,reducing the signal generator output level as necessary for
proper meter deflection.
After the previous step, the final signal generator level should be less -9 dBu for 12 dB SINAD.
