Plectron Paging
The Plectron paging feature requires a 4-digit prefix (capcode). 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 (Table 19) and Plectron Tone Group/Frequency Chart
(Table 20). 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
T
RANSMIT
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, according to the following
procedure:
1.
Locate the first two digits of the prefix (3 and 4 in this example) on Table 19.
2.
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 Table 19. Using the P number for the third digit of the prefix, determine
the correct tone group from the Table 20.
3.
Find the frequency of A tone (330.5 Hz) by locating the intersection of the tone group row with the
column headed by the third prefix digit (5 in this example).
4.
Find the frequency of the B tone is in the same manner by using the tone group for the fourth prefix
digit as listed in Table 19 below.
