[. . . ] In this example, the A tone number entered by the console operator is 4, which corresponds to 1251. 4 Hz. The second digit of the number from chart B (2 in this example) also corresponds to a number under Tone Group Frequency Chart Group #, and indicates which row of frequencies on chart will be used for the B tone. In this example, the B tone number entered by the console operator is 3, which corresponds to 669. 9 Hz. The previous example involves the console operator being required to enter two digits from the keypad (programming the number of 2-Tone digits accepted from the user on the selected channel to 2). However, if all three digits were required from the console operator (programming the number of 2-Tone digits accepted from the user on the selected channel to 3), the procedure for finding the frequencies from the Tone Group Frequency Chart would be the same, except that the most significant digit of the prefix would be the first digit entered from the keypad. If no digits were required from the operator (programming the number of 2-Tone digits accepted from the user on the selected channel to 0) both the A and B tone frequencies would be predetermined through programming and the same tone sequence would be sent every time a 2-Tone page is generated on this particular channel. Group Call A group call occurs when both tones of a 2-Tone paging sequence are the same frequency. If the console is programmed to allow 8-second group calls on a particular channel, then whenever a paging sequence is generated that consists of two tones of the same frequency, the page consists of an 8-second burst of that tone frequency. However, 8-second group calls do not apply when the GE code plan has been selected. In the GE system, a "diagonal" tone of 742. 5 Hz is inserted in place of the first tone if that tone is the same as the second tone. 06/10 26 IPE2500A and IPE2500A-MLS Paging Encoder/Desktop Controller Operation Example 2 Suppose the number of 2-Tone keypad digits accepted from the user on the selected channel is 2 and the GE code plan has been selected. Therefore, if the operator entered 55 as the paging digits and pressed the TRANSMIT button, the console would send the 2-Tone sequence A = 742. 5 Hz, B = 907. 5 Hz. This would alert a pager with a GE capcode of 455. Important NOTE: The 1st digit indicates Chart A Group # Source for the A tone, and the 2nd digit indicates Chart A Group # Source for B Tone.

Like 2-Tone paging, the capcode and code plan will determine at what frequency the paging tones will be transmitted. Plectron paging uses the Plectron Code Plan Chart and Plectron Tone Group/Frequency Chart. Refer to the example below and the tables to determine the capcodes you need. Plectron Paging Example Suppose the number of Plectron keypad digits accepted from the user on the selected channel is 0 and the capcode has been programmed to 3456. The A tone length is 1 second and the B tone length is 2 seconds. If the console operator were to press the TRANSMIT button, the console would send an A tone of 330. 5 Hz for 1 second, and then a B tone of 564. 7 Hz for 2 seconds. The frequencies for the A and B tones are determined from the charts that follow, according to the following procedure: 1. Locate the first two digits of the prefix (3 and 4 in this example) on the Plectron Page Code Plan Chart below. In the column beneath this two-digit number, there are two P numbers (P5 and P6 in this example) that correspond to tone groups on Plectron Page Code Plan Chart. Using the P number for the third digit of the prefix, determine the correct tone group from the Plectron Tone Group/Frequency Chart on page 30. [. . . ] No, low, or distorted transmit audio. If the receive audio is derived from a detector or discriminator, continuous noise is heard unless the receiving unit has an internal squelch circuit. Ensure that the microphone sensitivity is properly adjusted for the microphone in use. Ensure that the line output level is properly adjusted. Ensure that the microphone compressor is enabled.
