Press PTT then Y-State / 1300HZ Signal will be transmitted.Transmit Power will be 25W. 70 PRESS OK FSK:2100HZ LEVEL:050 DSC MOD 156.550 FSK + - 1. Press “FSK” softkey to change FSK signal to the B-state.2. Press PTT then B-State / 2100HZ Signal will be transmitted. Transmit Power will be 25W. 70 PRESS OK FSK:CONTINU LEVEL:050 DSC MOD 156.550 FSK + - 1. Press “FSK” softkey to change FSK signal to continuous mode.2. Press PTT then continuous signal will be transmitted. Transmit Power will be 25W. “FSK“ Soft Key Note: Please take a note for frequency set at test mode. CH70 frequency is set to 156.500MHz at test mode. CH70 frequency is 156.525 originally. We changed this frequency setting only for the test because there is possibility to interfere DSC communication at your area when you conduct this test longer time ( transmit longer time). Receiving frequency is set to 156.525. One of Japanese code less phone influenced DSC frequency recently in Japan and the unit is recalled. Therefore, we arranged as above for safety sake. But, DSC Tx frequency is set to correct frequency (156.525MHz) for actual DSC transmission.
