NOTE: The Beltpac must be turned on. It is normal for the number of successes to be 1 less than
the number of sends, even with 0 retries. This happens when the test is stopped before the Beltpac
responds to the last send.
Subcarrier Receiver (Rx) Test
The Subcarrier Rx Test is used to simply verify the Base is receiving data from the Beltpacs. It would
normally only be used if the Subcarrier Tx Test fails.
To perform a Sub Carrier Receiver Test:
• Press simultaneously the Beltpac C and D buttons. The C and D LEDs will both light and
stay on.
• Press
Start Test button.
After completing the test, be sure to turn off the Beltpac. It will remain in the test mode until it is
turned off.
Tone Generator Tests
Use the tone generator to produce full-amplitude audio tones for testing or adjusting audio circuits or
connections. The test tone can be applied to any or all audio outputs, including the base transmitters
and the wired intercom system.
To operate the internal tone generator, use DSP Tone Test function:
• Select the waveform type in the Signal box (Off, Sine, Triangle, Square or Impulse)
• Select Frequency in the Frequency box (50, 100, 300, 400, 700, 1kHz, 3kHz, 4kHz, 7kHz,
10kHz or 12kHz). The impulse signal is unaffected by the frequency setting.
• Select Output in the Output box (Ch1, Ch2, Tx1, Tx2, Aux OUT, Page, HSR, HSL, All HS, All
Tx or All).
To turn off the internal DSP Tone generator, select Off in the Signal waveform type list.
NOTE: Due to the digital sampling approach, the triangle waveform will not be smooth above 1 kHz.
The square waveform will have jitter above 4 kHz and always has some ringing on the edges. Use
caution when sending a tone into the wired intercom system. Excessive levels could damage
headsets or user’s hearing.
