Binary Test Mode
The Binary test mode is similar to the Audio test, however, it is used for setting deviation for
signals from the digital modulation output. While at the normal idle prompt, press the B +
CLEAR keys to activate the digital circuitry tests. After pressing the two keys the prompt
“binArY” is displayed. The encoder will accept the keys shown in Table 4.

for selecting test functions. The keys can be pressed in any order and
repeated as many times as needed. Press the CLEAR key to exit this test and return to the
normal operating mode.

DTMF Output Test
While the DTMF tone pairs are generated by a different source than the rest of the analog
paging signals, they come out through the same final audio stages as the other analog signals
and their level is adjusted using the same control, R26. If the Audio test has been done
correctly, it is very likely that you will never need to test the DTMF tone pairs
independently. However, if you do need to fine tune the DTMF performance, this test makes
that possible.
The DTMF test mode is entered by first removing power from the encoder, and then holding
down the ENTER key while re-applying power. When you hear the DTMF tone, release the
ENTER key. The key pad is now live. As you press the keys, the encoder will display the
digit and send out the DTMF tone pair. All sixteen pairs are supported.
Press the CLEAR key to exit this test and return to the normal operating mode.
EXCEPTIONS
Zetron engineers are available for consultation on exceptional installation connections not
described above.
CABLE OPTIONS
Drawings for any option interface cables that were ordered with the encoder are included with
your order.
